Comment on: Topic 'Crenellation pattern trough a set of points': rella - Revit/AECOSim etc etc) then scripting is the only way to do business. In fact Dynamo/Generative Components would be your main parametric app ... but GH can offer a thing or two as well. Other than that here's a very brief explanation upon the "steps": 1. Using connectivity trees (faces to edges, edges to faces, faces to faces) ... 2. ... Find the "internal" edges (meaning edges that are connected to more than ONE face) and store them in a tree. Doing this find the smallest edge as well (for defining the "module" of the pts divisions minus the start/end offset). Used an object type tree since I store the indices of the adjacent faces as well (an object type is a "general" container that can hold cats, dogs, numbers, bananas etc etc ... with the cost of un-boxing when an item is to be used [Note: un-boxing costs time but in this very simple case we can afford the "luxury"]). NOTE: if you observe the paths on that tree you'll notice that they correspond 1:1 to the indices of the related edges in the EList List (of type Curve). 3. Loop withing the "interior" edges and define the coplanar vectors per edge related with the 2 adjacent faces. These vectors are the Cross Product (Google that) between the edge direction and the normal per face (at u/v: 0,0). Divide the edge (taking into account the start offset AND the ratio of the edge length/ minEdge [as derived from phase 2 as above]). Using these points create a "zing-zag" polyline and store it in the same path as the OEM edge. NOTE: The polyline is not planar since each teeth is laying to the corresponding adjacent face plane (if the Brep Faces are not planar more "smart" stuff is required). From this point (not included in V1): 4. Using Face to Edge connectivity data: IF a path exists (in the polyline tree as in 3 above) with the given index sample this polyline as Curve ... if not get the OEM Curve (case: "boundary"/perimeter Brep Faces). Join the Curves (take provision to report failures) and project them to the corresponding Brep Face plane (case: planar face) or ... to some suitable "mean" plane. Define a planar Brep out of the newly created closed planar Curve and extrude it (actually the Brep Face of it) both sides at once for doing a "solid". If Brep Faces are not planar ... well things are a bit more complicated (not nuclear science ... just another approach is required). In fact ... is a bit more challenging than that since there's assembly tolerance AND clash issues around ... but this is the "general" idea anyway. …; Added by peter fotiadis at 1:00am on January 19, 2017

Topic: Best language to learn for beginners and is it worth it?: need custom scripting. I've always been a self taught sort of person. When I was younger I did simple html. Just recently I taught myself very basic python scripting. My guess would be probably what a first term student would learn. Just enough to copy and paste code for a visualization program my client used. I had some basic question for you computer science majors. First and foremost I would like to say I am always humbled by the skill set and high level understanding of math you guys posses. I would like to thank anyone who takes the time to read and respond to my post. What is the best language for nurb based design? I rarely use meshes. The main problems I have, are usually about trimming, surface transition, curvature and stitching for 3d printing and manufacturing. How long would it take me to understand and write my own code? I have no delusions on how hard it is to get to that level. I do not think it's easy, I do not think it will take me a couple months to wrap my head around. I know if I were to embark in this journey, it would take me a very very long time. I am in no hurry. Is it even worth it? I have my own company. I work around 70 hours a week. I know class A Nurb modeling, polygon based modeling, photorealistic cpu and gpu based rendering, it's coming to the point where I feel I might be spreading myself too thin. Whats the usual rate for a programmer who knows what he is doing? I know theirs always cheaper people who might get my problem solved, but I believe that talent is expensive because it is worth every penny in the long run. I do contracting work too. I always have to tell my clients how the previous contractor did such a horrible job, I would have to start from scratch. Where do I start? I don't like classes. I like books, tutorials and google. Regardless if it makes financial sense for me to start, I believe in education for the sake of self improvement. I also think computer science forces your brain to understand complex concepts and that, in turn, makes you a smarter person. Thanks again and I hope you guys have a good day. …; Added by Raymundo Burgueno at 12:23pm on December 3, 2014

Comment on: Topic 'rotate 3d': input orientation of the objects. I can see that you've already done this with Vec2pt. Doing it with a sun vector is a little easier, because you are working with one vector, not a bunch of different vectors. you probably know a lot of this already, but I wanted to write a comment that is helpful to anyone coming across the discussion, because it is a common design task. To orient a bunch objects towards a sun vector: 1. you need a vector to represent the sun's rays. You can either use an existing definition from the web (definitely look at Ted Ngai's amazing work on this), or just make a single adjustable vector as a stand in. I've often simply made a vector using azimuth and altitude angles as inputs, since those are common ways of describing the location of the sun, and makes it easy to look up a sun angle and put it in to your definition. 2. assuming you have some vector to represent the sun's rays, make a plane that is perpendicular to this vector. But Why, Precisely?, you're already familiar with some of the quirks of making a plane perpendicular to a vector, just keep those quirks in mind. 3. next, create reference planes for your panels. If your panels are flat (i.e. planar) this is really simple, just make a list of their planes, using whatever you like (check planarity, evaluate surface, whatever). If your panels are not planar, then you need to decide on a plane you can make from each one that you would like to use as a reference plane. plane from 3 points might be a good method here. 4.take your single plane that is perpendicular to your single sun vector, and place it at the origins of all of your reference planes. Now you have a sun-oriented plane for each panel. 5. Using the orient component, input your reference planes as the reference planes, and input your sun-oriented planes as the target planes, and input your panels as the geometry to transform. You should now have a bunch of panels oriented to the sun vector. 6. In this method, I've assumed that you want your panels perpendicular to a solar vector, to face the vector, but if you want a different relationship to the sun vector, you just need to change the relationship of that single first sun-oriented plane to whatever relationship you would like to make. One thing to think of when designing for sun angles is just that at any given point in time, for any given point on the earth's surface, the rays of the sun are basically parallel. the angle of these rays changes over time, but at any other time, the rays are still parallel to each other, and can therefore be described by a single vector for each moment in time.…; Added by Benjamin Golder at 1:29pm on December 10, 2009

Comment on: Topic 'Forum Bug: Posts are Posted Multiple Times': o my work, not just as a portfolio but as a visual index reference for myself to find things in my "online notebook." Otherwise my notes are scattered on various devices. I've also been locked out of Discourse.McNeel.com for weeks going on months, even with a new email address, even from different IP addresses, "temporarily." I'd rather hit refresh and delete duplicate submissions than be locked out completely. Just fix this forum so the comment button works instead of hangs. How will you include the astonishingly useful Grasshopper component reference on a text-based site like Discourse? "Leave it to computer programmers to screw things up, they always will." - Motto of our age. ARE YOU KIDDING ME?! Look at this low information bandwidth page, and you *want* that? The 1990s are calling, just like Rhino itself is being overtaken by Autodesk in general, this is just embarrassing. Another user is calling to delay and censor gallery content. It takes ten minutes to see a year's worth of image uploads here. It takes forever to see them on Discourse, since there is no gallery at all. If you moderate image uploading, I will stop uploading them at all too, on and off one of this forums most active contributors. If you abandonware this forum into obscurity, as some old archive site, you are destroying my professional portfolio that I use to find work and find clients. I will likely just switch to Dynamo if you ruin this forum with Soviet worthy aesthetics. YOU JUST NEED TO FIX A SUBMIT BUTTON. That's all. Otherwise you are a big boss shutting down the coal mine because you couldn't fix a switch. Computer programmers should not be dictating forum interfaces! Since this site will have to remain the reference page, my seeing nothing like them on Discourse, a text-interface site, that means Grasshopper will then have two homes, greatly confusing to young and old alike. If you want to switch forums, you need to build a serious site with a modern web interface, and migrate Discourse.McNeel.com over to that, not abandon the most valuable community McNeel has, and it's not Discourse, it's *this* creative forum. You should also migrate completely, if so, to move our galleries over to the new site. And, no don't CENSOR the damn galleries, just look at the visual version of ZBrush forums, etc. where users upvote image, so you can view the galleries by popularity.…; Added by Nik Willmore at 11:57am on October 11, 2017

Topic: Low light levels produced from IES files Honeybee: I have the IES files from the manufacturers. I am able to get the IES files to load and run in Honeybee. However the light levels being produced are low and very localized to the light source. I am trying to determine if it’s some scaling, etc that needs to be modified. Within Honeybee there is a “CandelaMultiplier” which allows me to increase the values, but I don’t want to do it arbitrarily nor am I sure this is truly solving my problem. If anyone has any insight as to importing IES files into Honeybee and things that need to be factored and considered that would be appreciated. I'm experiencing the situation with other IES files as well. Thank you!
