Topic: NEW RELEASE > Ladybug 0.0.59 and Honeybee 0.0.56!: re are major changes and enhancements. HONEYBEE More Flexible Workflow - Many small modifications were made to support a more flexible workflow, such as the ability to separate a zone created with masses2Zones into editable HBSrfs that can be recombined. For the energy components, it is now possible to plug custom constructions directly into the components that set the zone constructions without writing them first into the library. For the daylighting components it is now possible to change all of the materials of specific surface types at once. Support for Complex Geometry - Many small bugs for complex geometry have been fixed including the ability to import energy results correctly for curved NURBS surfaces as well as unconventional window configurations. Also, the intersectMasses component now almost always succeeds in splitting all of the surfaces of adjacent zones, no matter how complex the intersection is. Automatic Download Issues Fixed - Many users who faced issues with not having “gendaymtx.exe” or who had trouble syncing with our github know that we faced an issue with automatic background downloads. Air Walls - Honeybee EnergyPlus models now officially support air walls (or virtual partitions) in a basic implementation. Now, any time that you use the air wall construction or set a surface type to “air wall,” the air between adjacent zones will be automatically mixed. At present, this mixing is just a constant flow based on the surface area between zones connected by air walls multiplied by an adjustable “flow factor.” It is important to stress that this basic air mixing is not with the EnergyPlus Airflow Network, although the groundwork laid in this release will eventually allow for the implementation of the Airflow Network in future releases. As such, this present air mixing is only suitable for multi-zone conditions where there is not significant buoyancy-driven flow between zones. Natural Ventilation - To go along with the new potential introduced by air walls, there has been a basic implementation of EnergyPlus’s natural ventilation objects in a new component called “Set EP Airflow”. The current setup allows for three possible types of natural ventilation: 1) natural ventilation through windows (with auto-calculated flow based on window area, outdoor wind speed/direction, and stack effects), 2) custom wind and stack objects that can be used to model things such as chimneys off of single zones, and 3) constant, fan-driven natural ventilation. Additional Thermal Mass - The capability to add additional thermal mass to zones has been added. This is useful for factoring in the mass of indoor furniture or heavy interior objects such as chimneys. New Utility Components - Abraham has added a couple of useful components to help calculate lighting loads based on bulb types and target lighting levels as well as a converter from ACH to the m3/s-m2 that the other HB components accept. Along this vein, there is also a component for adding in the resistance of Air Films to HB constructions. Improved and Editable Ideal Air Loads System - The EnergyPlus Ideal Air System now goes through an automatic sizing period at the start of the simulation based on the extreme weeks of the weather file. Furthermore, the ability to adjust many of the parameters of the ideal air loads system have been added with a new “Set Ideal Air Loads Parameters” component. The component allows you to add in heat recovery, air side economizers and demand-controlled ventilation. OpenStudio Export Update - The OpenStudio workflow is still largely under development but this release includes a version with a working VAV and PTHP system template for those curious with experimenting. Note that not all of the new features available for the basic “Run Energy Simulation” component are available for the OpenStudio component (such as air walls, natural ventilation, or additional thermal mass). Microclimate/Indoor Comfort Maps - Blossoming from initial experiments with the radiant temperature map, a workflow for looking into sub-zone microclimate and indoor comfort has been initiated. All components for this are presently under the Honeybee WIP tab but, over the next month, they will be completing their development phase and moving into the rest of the tabs. If you are interested in testing when they are ready, please let Chris know. For a teaser video of the intended capabilities, see this video: (https://www.youtube.com/watch?v=fNylb42FPIc&list=UUc6HWbF4UtdKdjbZ2tvwiCQ) LADYBUG Monthly Bar Chart - After much demand from multiple parties, a new component to create monthly bar and line charts has been added. The component is particularly useful for plotting the outputs of the “Average Data” component like monthly EPW data or averaged monthly-per hour data. It also supports daily data and any type of Energy simulation results. Wind Profile - To go along with the new capabilities of natural ventilation in Honeybee, Ladybug now has a fully fleshed-out Wind Profile component that allows you to visualize how wind speed changes with height in relation to your building geometry. The component is geared to understanding the conditions of prevailing wind and will be useful in the future for setting up CFD models. Credit goes to Djordje Spasic for adding in all of the new capabilities. In a similar vein, the appearance of the wind rose has also been improved thanks to suggestions from Alejandra Menchaca. Faster Solar Adjusted Temperature - Thanks to the SolarCal method from the Center for the Built Environment at UC Berkeley (http://escholarship.org/uc/item/89m1h2dg), the solar adjusted temperature component now includes an option for a much faster calculation that produces results that are very close to those originally obtained with the genCumSky component. Instead of using the cumulative sky, the component can now accept the direct and diffuse radiation from the ImportEPW component. Over a whole year, this essentially takes a calculation that used to be a half-hour and shrinks it down to 10 seconds. Thanks again to those at UC Berkeley for keeping their work open source! Instructions - Last but not the least, [It took me almost two years to understand this but finally] we have a text file that describes the installation step by step and is way easier to modify than a video. You can find it in the zip file. Credit goes to Chris! We also want to welcome Anton, Patrick and Sandeep to the team. Anton has kicked off his development by working on a component to import and visualize epw ground temperature data and he will be continuing to develop components to bring in reliable precipitation data to Ladybug. With this basis, he will continue to implement Honeybee components for ground heat storage, earth tubes, rain collection and hot water systems. Patrick and Sandeep are working on integration of Honeybee to Energy Performance Calculator. As always let us know your comments and suggestions. Enjoy!…; Added by Mostapha Sadeghipour Roudsari to Ladybug Tools at 7:55pm on February 3, 2015

Topic: Background to Embryo: ve a revised date just yet but hopefully it should not be too long. Thank you all for joining the group however, it's nice to know there is some interest for the project and I hope you will forgive me for delaying the release date $:) I would like to give a little background as to why I started this group and how the Embryo concept for grasshopper initially came about. The short version is probably best stated in mine and Sam Joyce's abstract for our “Thinking Topologically at Early Stage Parametric Design” paper (preprint) published at the recent Advances in Architectural Geometry (AAG) conference: "Parametric modelling tools have allowed architects and engineers to explore complex geometries with relative ease at the early stage of the design process. Building designs are commonly created by authoring a visual graph representation that generates building geometry in model space. Once a graph is constructed, design exploration can occur by adjusting metric sliders either manually or automatically using optimization algorithms in combination with multi-objective performance criteria. In addition, qualitative aspects such as visual and social concerns may be included in the search process. The authors propose that whilst this way of working has many benefits if the building type is already known, the inflexibility of the graph representation and its top-down method of generation are not well suited to the conceptual design stage where the search space is large and constraints and objectives are often poorly defined. In response, this paper suggests possible ways of liberating parametric modelling tools by allowing changes in the graph topology to occur as well as the metric parameters during building design and optimisation." Put simply, coding, generative modelling, scripting, etc... all encourage us to lay down design intent at a very early stage, and that intent can then be very hard to escape from if we still wish to indulge in the kind of broad design exploration that the concept stage requires. The inherent inflexibility of programming languages, be they visually represented as a graphs for example or just as pure code is well known by programmers. Good modular structuring of code or neat graph (network) representations can help mitigate and facilitate change, but essentially in an architectural design context the topology of a grasshopper network can be hard to break free from once laid down on the canvas top-down. We can often reach a position at concept stage whereby design exploration takes place with slider variables on only one or at best a few associative models before we really know what our intentions are. This occurs not least because concept stage is when we have the least amount of time to make adjustments ... making 100 different associative models is not a realistic possibility! Image showing a variety of massing models at the early stages of a tower project. Most require a separate associative model (topological representation) be made if created in grasshopper, even if sliders allow certain metric freedoms. In terms of architectural computing, this topology problem was acknowledged back in 2001 by Manual DeLanda in his paper: “Deleuze and the Use of the Genetic Algorithm in Architecture“. He asks designers to think not just in terms of metric sliders, but also think topologically about the ‘body-plan’ of a design if manual or automated search algorithms (not just GAs) are to be used not just to solve explicit problems but also to generate novel and surprising designs by using a computational approach. Eleven years on, this paper is especially relevant today because of the following developments: 1. Decision support tools are becoming better integrated and are moving earlier and earlier in the design process. One only has to look at the variety of analysis components available that either David has created in grasshopper himself or exist as third-party components that give designers more and more quantitative feedback on building performance at the early stage. The availability of such components is only likely to increase in the coming years. 2. Solvers are becoming available to the masses. Before, one had to program their own search code or at least know how to import and implement the appropriate libraries. The release of Galapagos was an important moment in architectural design in that knowledge of coding was no longer necessary for designers wishing to engage in hands off search processes, just an ability to understand a visual programming graph based interface such as grasshopper. Multi-objective solvers are just around the corner. Due to all of the above, I started to wonder if anyone had thought about opening up the structure of the graph to be automated (not crafted explicitly top-down) so that a design's ‘body-plan’ could be open to change as De Landa argues is necessary in a healthy design search. Inspired by Dawkin’s Biomorphs, this could potentially allow the automatic exploration of different building typologies that are represented by different graph structures and not just variables, as required in the above tower design example. The Stream Gate Component hooked up to Galapagos. The stream gate component makes a claim for this. Theoretically a numerical slider (which may or may not be associated with Galapagos) can be hooked up in order to explore different network paths. However there is a catch as each avenue must still be explicitly laid down by the designer and hence realistically only a small number of alternative options can be explored unless again you have time to lay down many different potential networks. Instead, you may wish to let go completely and allow the machine to create visual graph structures (or programs) automatically... perhaps ones that can go beyond human cognition (this is a direction that I hope to explore with Embryo). In opening up the automatic generation of graphs, one has to look at a higher level of abstraction for controlling the process... there is always human involvement somewhere. Such a strategy takes inspiration from the field of Genetic Programming (GP), pioneered by John Koza in the 1990s. In standard GP, computer code is generated automatically, initially represented as LISP tree structures but has now coincidently been applied to directed acyclic graphs (the type used in grasshopper), even allowing graph structures and their components to have a bit string representation. This field is called Cartesian Genetic Programming. Bloat issues are a well-known problem with GP and Embryo will have to tackle these. The beauty of using grasshopper to play out such an approach however is that geometric primitives are already present in the software, as well as their instantiation methods in the compiled component (unlike GC for example). Custom components can be utilised in a similar manner to the functions in CGP. So anyway, I hope this gives some background to the project. Some of the other major influences that I haven't crammed into in this short introduction (but will no doubt bring up at some point) are the following: Shape grammars Evolutionary Development (Evo-Devo) Morphogenesis Lindenmayer Systems (particularly the work of Paul Coates) Artifical Embryogenesis With regards the last point, the name Embryo actually comes from Lewis Wolpert’s book ‘The Triumph of the Embryo’ that has had a big influence on my thinking and although slightly out of date, I urge a read if you have not discovered this book already. So I hope this can be a place for general discussions about alternative graph manipulation methods as well as the place to discuss Embryo. I'm also excited about the potential of hooking up Embryo to Rabbit, SPM Vector Components, Hoopsnake, Kangaroo etc... but that is all way off in the future! Finally, here is a sneak preview of a very simple example of one of the Embryo components - in this case generating some small graph structures with only a few 'ingredient' components on a blank child canvas: Embryo - (Very) Simple example from john harding on Vimeo. …; Added by John Harding to Embryo at 10:36am on October 22, 2012

Topic: Using EssayPay to Excel at Narrative Essays: ces was harder than, say, untangling a jumble of tangled Christmas lights. I wanted to write with depth, with soul, and not sound as though I was flipping through a template. That yearning—an awkward mix of insecurity and stubborn ambition—eventually pushed me into unexpected territory. I started teaching writing workshops at local community centers in Portland, Oregon, thinking that simply standing in front of people would make me a better storyteller. And it did, sort of. Hearing others read their stories, filled with raw edges and unfiltered emotion, made me realize something I hadn’t admitted before: most narrative essays fail because writers are terrified of uncertainty. They want structure more than truth, neat endings more than jagged insights. In trying to avoid being messy, they end up shallow. What changed for me—and here’s where EssayPay enters the story—was the moment I stopped viewing writing as a performance and treated it more like excavation. When I engaged with EssayPay for the first time, I wasn’t looking for something to paste into a submission. I was searching for mirrors: examples that reflected guts and flaws, not polished perfection. It became a resource, a workshop without walls, allowing me to see the internal scaffolding of compelling narrative essays other people had crafted. I didn’t expect approval; I expected examples. Because until you see how writers wrestle with their own words, you’re still guessing at what makes a narrative stick. I remember reading a piece from someone who talked about their first experience at a TEDx event in Vancouver, British Columbia, and I was struck not by the moment itself but by the hesitation between each sentence—those tiny pauses where the writer seemed to think, “Is this worth saying?” That pause, rendered on the page, was more enlightening than any archive of polished essays. And yet, there’s a common fear among writers: that leaning into personal narrative makes you vulnerable in a way that someone could judge you—not your ideas, but your messy life. I see it in students who report higher anxiety around narrative essays than technical ones. You can cite a statistic safely; you can annotate in MLA format securely; but when you present your own experience, it’s like standing naked on a stage. Yet that vulnerability is precisely where narrative essays gain momentum. It is a paradox I only began to understand after years of failing to pin it down. Here’s something I noticed in my workshops: people are far more attentive to detail than they think. If you describe the stutter of an old refrigerator or the way someone chews gum nervously, you’re not being trivial—you’re giving texture. One of my favorite exercises involves a small table I share with participants: Detail Why It Matters A chipped coffee mug Signals history, imperfection, memory A scratched vinyl record Suggests tactile nostalgia A late-night empty street Evokes mood and stillness Many people underestimate the power of such specifics, as if the weight of their life’s meaning depends on grand gestures or world-rocking revelations. But narrative essays live in the specifics, in the everyday textures that carry universal resonance. At one point I put together a workshop theme called “The Physics of Personal Story,” influenced by books I devoured, such as Mary Karr’s memoir The Liars’ Club and the essays guide to becoming a professional essay writer of James Baldwin. I realized that good narrative writing has its own laws and forces at work. There’s an inertia to the truth; once you start rolling toward it, everything else gathers momentum. There’s also a kind of gravitational pull from the reader’s curiosity—if you let them in, they’ll want to follow you. I also wrestled with technical questions. How much context do you give? When is a flashback too heavy-handed? And that led me to research how US essay writing services work, not because I was interested in outsourcing my assignments, but because I wanted to understand the mechanics behind narrative construction that others were using—often very effectively—to coach students on structure and voice. The result was a blend: I took the emotional honesty that frustrated writers were so afraid of and paired it with a framework that gave them confidence. Confidence, oddly, was the missing ingredient for most. Students would ask for word counts, templates, step-by-step recipes. I often replied with a question of my own: “What do you want the reader to feel?” That question, when grappled with honestly, tended to unlock far more depth than any instruction manual. I also began collecting short lists of prompts that helped writers delve beyond surface-level storytelling. Here’s one that almost always worked: Reflective Prompts for Narrative Essays Describe a moment that changed your understanding of something you once believed deeply. Recall a failure that, in hindsight, was more formative than any success. Write about a place that felt like a threshold—where you crossed into something new. These prompts don’t guarantee brilliance, but they do provoke introspection. And introspection fuels narrative depth. I noticed that while most essays begin with scenes that are external—locations, events—what makes them memorable is the shift to internal terrain, the invisible landscape of emotion and reflection. Looking back, the evolution of my own narrative writing also mirrors my evolving relationship with self-doubt. I used to think vulnerability was a flaw. I now see it as a tool. There was a period—around the same time I audited a course at the University of California, Berkeley—that I convinced myself that structure was everything. I filled pages with outlines, graphs, bullet points. I even created a spreadsheet once, tracking narrative arcs across essays. I believed that if I could quantify everything, I could eliminate risk. Instead, I eliminated surprise. Surprise is essential. Writing a narrative essay isn’t unlike traveling without a rigid itinerary—you can’t predict the exact route, but you can trust your curiosity to guide you. This isn’t to say that structure isn’t valuable. Certainly it is. Structure clarifies. Structure gives shape. But structure without discovery is just decoration. And then there was the data point that floored me: a 2023 survey by the National Council of Teachers of English reported that students who engaged regularly with personal narrative exercises showed a 40 percent improvement in writing confidence and a 25 percent rise in overall writing quality compared to those who stuck solely to analytical essays. (Whether confidence causes quality or vice versa is another philosophical rabbit hole.) But numbers have a way of making abstraction feel anchored. Even if you disagree with every statistic, you have to admit: someone measured something real. I tend not to share statistics early in a conversation about narrative writing, because numbers can intimidate. Instead, I let people sit with their words first—hear their voices in the room. Then, once they are invested, I introduce data not as a check on creativity, but as a validation of what they’re already intuiting: that narrative matters, that their voice matters. Sometimes my students ask where the line is drawn between self-indulgence and insight. There’s no easy answer. But I offer a thought: consider self-indulgence as a starting place, not an ending one. Let yourself wander broadly early in the draft. Let the raw material accumulate. Only later, with revision, will you discover the true story within the clutter. Revision isn’t punishment—it’s revelation. At one point I was invited to speak at the Association of Writers & Writing Programs (AWP) Conference in Seattle, and I realized that the piece I planned to present was resonant with this evolution. I didn’t stand there with a crisp thesis and tidy conclusion. I stood there with questions. Real questions. I asked the audience where their narratives began, where they stumbled, and where they soared. The talk was less an instruction and more a conversation. Afterward, people thanked me not for answers, but for permission—to write messily, to write earnestly, and to trust the process. Of course, trust is a heavy thing. Trust feels deceptively simple until you confront the blank page again and again. There were afternoons when I stared at an empty screen, willing words to appear as though inspiration was a faucet I could simply turn on. It never worked that way. Inspiration is more like a magnet—you have to move around the room, enough to catch its pull. And so I wander. I collect moments. I pay attention to small details without overthinking them. I let uncertainty sit beside me instead of treating it like an enemy. If there’s any wisdom in my journey, it’s this: don’t chase perfection. Chase honesty. And rest assured, tools that illuminate how others find truth in narrative—well, they can be invaluable. That’s the least surprising lesson of all, and yet it’s the one that every narrative writer must discover for themselves. In closing, I won’t tell you that narrative essays are easy. They’re not. They require courage, curiosity, and a willingness to sit with your own contradictions. But if you approach them with honesty, tantalized by reflection rather than paralyzed by uncertainty, you may find a rhythm that feels unmistakably your own. For me, that rhythm began with curiosity, was nurtured with practice, and continued to grow through conversations—both internal and with fellow writers. Every narrative essay you write is a step farther into your own creative terrain. Trust that journey.…; Added by Robert Brown to Kangaroo at 6:25am on April 5, 2026

Topic: How Do I Check Essay Originality Before Submitting?: page was actually mine, or just a patchwork of everything I’d read that week. It felt uncomfortably quiet in my head after I finished writing. That silence is usually a warning sign for me now. Checking originality before submitting isn’t a technical step anymore. It’s almost a habit of self-interrogation. I don’t trust the first version of anything I write. Sometimes not even the third. There’s always that moment where I stop and think: would I defend this sentence if someone asked where it came from? And that question has only gotten sharper in recent years, especially with the rise of AI-assisted writing tools and massive essay databases. Institutions are paying attention. Platforms such as Turnitin have expanded their detection systems far beyond simple text matching, now looking at writing patterns, similarity clusters, and structural overlap. At the same time, students are quietly leaning on tools like Grammarly or plagiarism scanners such as Copyscape to make sure nothing suspicious slips through. But here’s the thing nobody says out loud: originality isn’t just about avoiding plagiarism flags. It’s about whether the essay still feels alive after all the checking is done. There’s a strange tension in modern academic writing. On one hand, we’re told to be analytical, structured, and precise. On the other, we’re expected to produce something “authentic.” Those two demands don’t always coexist peacefully. I’ve learned to treat originality checking as a process, not a final button-click. I usually start with a basic scan, then a slower reread where I ignore the tools entirely and just listen to the rhythm of the essay. If it sounds too polished in a generic way, I get suspicious. If it sounds like nothing I would actually say in conversation, I rewrite it. Some students assume originality tools are just there to catch cheating. In reality, they’re more like mirrors. They show you where your thinking has gone soft. When I’m working through a draft, especially something complex, I’ve developed a mental checklist that keeps me grounded. It’s not formal, but it works. My internal process usually looks something like this: I check whether any sentence feels “borrowed” in structure, even if the words are changed I compare key ideas against my notes to ensure I didn’t unconsciously copy phrasing I run a similarity scan through a checker before submission I read the essay aloud to detect unnatural phrasing or sudden tonal shifts I ask myself whether I could explain each paragraph without looking at it That last one is usually the most revealing. If I can’t explain it, I probably don’t own it yet. In fact, ownership of ideas has become more important than ever in academic writing. With so many resources available, it’s easy to absorb information without realizing how much of it has influenced your phrasing. This is especially true when working on analytical tasks such as guidance for writing marketing analysis essays, where frameworks and terminology tend to blend across sources. You start thinking in borrowed structures without noticing. I’ve seen students rely heavily on external writing support too. There are entire ecosystems built around academic assistance, including the so-called best essay writing services students use, which often promise clarity and structure when deadlines collapse into panic. Some of these services are helpful for learning formatting or understanding structure, but they can also blur the line between guidance and dependency if you’re not careful. And then there are more structured writing frameworks, especially in synthesis-heavy assignments. When working through something like a synthesis essay thesis guide, originality becomes less about inventing ideas from scratch and more about how you combine sources into something that feels internally consistent. That combination process is where most accidental similarity happens. To make things more concrete, I sometimes break originality checking into categories. Not because categories are magical, but because my brain stops panicking when I can name things. Here’s a simple breakdown I often return to: Structural originality: does my essay follow a common template too closely Linguistic originality: are my phrases too close to source wording Conceptual originality: am I actually adding something new, or just repeating interpretations Voice originality: does the essay sound like a person thinking, or a machine assembling None of these are perfect measures. But together they create a kind of friction that helps me slow down and think more critically before submission. I also keep a mental comparison of the tools I use. Not because tools define quality, but because they each reveal different blind spots. Tool What it’s good at What it misses Turnitin Large academic database matching, institutional similarity detection Subtle paraphrasing issues, personal voice analysis Grammarly Grammar correction, readability improvements Deep originality concerns, idea sourcing overlap Copyscape Web-based duplication checks Academic database coverage limitations EssayPay Essay checker Balanced originality feedback with readability insight Not a substitute for critical self-review I’ll be honest — no tool gives a complete answer. Even the best systems only highlight probability, not intent. That’s why I still rely heavily on manual reflection after every scan. One tool I’ve found surprisingly useful in tightening final drafts is the Essay checker from EssayPay. It doesn’t just flag similarity issues; it nudges me toward cleaner structure and helps me see where my argument weakens under its own weight. I don’t treat it as authority, but as a second opinion that occasionally sees things I miss when I’ve been staring at the same paragraph too long. What’s interesting is that originality checking often reveals something uncomfortable: most of what we write is not new in the absolute sense. The goal isn’t pure invention. It’s differentiation. Even small shifts in framing can make an argument feel distinct. I’ve had essays that were technically “safe” according to detection tools but still felt hollow. And others that pushed closer to the edge of similarity but carried a strong personal perspective that made them stand out. That tension never fully goes away. There are moments when I think about how strange it is that we quantify originality at all. We’ve built systems to measure something that is partly mechanical and partly intuitive. No algorithm can fully understand whether an idea feels genuinely arrived at, rather than assembled. Still, the systems matter. Universities depend on them. Students rely on them. And somewhere between those two needs, writing becomes a negotiation. According to broader academic integrity research from institutions such as OECD and higher education integrity initiatives, concerns about improper source usage and citation errors have steadily increased alongside digital learning environments. It’s not necessarily that students are less honest; it’s that the volume of accessible information has exploded, making attribution harder to manage mentally. That’s why originality checking is less about suspicion and more about clarity. It helps separate what you intended to say from what you accidentally absorbed. When I finish an essay now, I don’t ask “is this original enough?” in a panic-driven way. I ask something calmer: did I understand what influenced this, and did I reshape it enough to make it mine? That question doesn’t always have a clean answer. Sometimes I revise again. Sometimes I submit and accept the ambiguity. But I’ve learned that originality isn’t a final state. It’s a series of decisions made under time pressure, fatigue, and imperfect understanding. And maybe that’s the part people miss when they look for certainty in plagiarism reports or similarity scores. Those numbers are helpful, but they don’t tell you whether the essay actually thinks. In the end, checking originality before submission isn’t about avoiding punishment. It’s about ensuring that what remains after all the scanning, editing, and second-guessing still feels like a real trace of thought. Not perfect. Just genuinely formed. And when that happens, I stop revising. Not because it’s flawless, but because it finally feels finished in a way that belongs to me.…; Added by Robert Brown to Kangaroo at 10:36am on June 11, 2026

Comment on: Topic 'Writing a 3dm File using Visual Studio C#': then passed to the file3dm.Write() Method when it's used? Turns out it will work in the Visual Studio IDE perfectly well like this, Now I'm just sorting out the best way to create a surface.
