Introduction to Grasshopper Videos by David Rutten.
Wondering how to get started with Grasshopper? Look no further. Spend an some time with the creator of Grasshopper, David Rutten, to learn the
utput. A typical parametric analysis involves either toggling input parameters while observing an output response in a cyclic trial and error feedback loop, or by adopting an optimisation approach to search for the 'best' output value based on some target of interest (e.g. in parametric simulation analysis studies).
Either-way, it remains cognitively difficult to keep track of input-output relationships, especially in multi-input parameter scenarios. Furthermore, optimisation outcomes are one-off outcomes that do not provide insight into the underlying input-output causality that is responsible for generating the output in the first place. As a result, it becomes challenging to control the computational workflow intuitively.
Inference Lab is a plug-in that overcomes such challenges by introducing bi-directionality between inputs and outputs, within Grasshopper. In other words, Inference Lab facilitates both forward and inverse computations. An inverse computation implies the ability to set a target output value of interest and instantly reveal the input distributions that are likely to cause the set target. This facilitates an instant cross-section of the input-output mapping. Inference Lab enables interaction with the input and output distributions to explore the cause and effect bi-directionally.
The following demo video illustrates the potential of Inference Lab for a structural design scenario. Given a typical parametric FEA simulation set up, Inference Lab was used to identify 1) how the design parameters influence the maximum deflection and the weight of the cantilever truss structure, and 2) identify the parameter ranges that satisfy specified targets on max deflection and weight.
Under the hood, Inference Lab builds a statistical representation of the input-output workflow from data that is generated automatically from the parametric definition within Grasshopper. The statistical representation takes advantage of a marriage between machine learning and Bayesian inference (a classic technique from probability theory).
More literature about the research underlying Inference Lab can be found here.
Inference Lab is presently composed of four main components: 1) PSlider, 2)POutput, 3)DataGenerator, 4)Model Builder.
Notes:
Inference Lab is a by-product of my very recent PhD work so please forgive me for the lack of information. I intend to update this page with structured tutorials explaining the potential of Inference Lab in various scenarios.
The Inference Lab plug-in is not yet available for download as I am in the process of ironing out a few minor issues. I hope to share an alpha version very soon. …

Computational couture looks at the creation of exclusive custom-fitted clothing (typical of haute couture) through the lens of a systemic approach, extending the sartorial techniques with 3D modeling and computation-based approaches developed in Rhinoceros and the visual programming environment Grasshopper.
Aim of the workshop is to exert, infuse and expand the sartorial sensibilities to body proportions and dress making into an algorithmic approach that loops through design and fabrication by means of laser cutting and 3d printing for the design and production of a garment. Participants will be divided in teams focusing on specific aspects of the garment related to the production technique (laser cutting or 3D printing).

large scale prototyping techniques. The programme continues to build on its expertise on complex architectural design and fabrication processes, relying heavily on materiality and performance. Autumn DLAB brings together a range of experts – tutors and lecturers – from internationally acclaimed academic institutions and practices, Architectural Association, Zaha Hadid Architects, among others.
The research generated at Autumn DLAB has been published in international media – ArchDaily, Archinect, Bustler – and peer-reviewed conference papers, including SimAUD (Simulation in Architecture and Urban Design), eCAADe (Education and research in Computer Aided Architectural Design in Europe).
Autumn DLAB investigates on the correlations between form, material, and structure through the rigorous implementation of computational methods for design, analysis, and fabrication, coupled with analog modes of physical experimentation and prototype making. Each cycle of the programme devises custom-made architectural processes through the creation of novel associations between conventional and contemporary design and fabrication techniques. The research culminates in the design and fabrication of a one-to-one scale prototype realized by the use of robotic fabrication techniques, with the aim of integrating of form-finding, material computation, and structural performance.
The programme is structured in two stages:
PART 1 – participants are introduced to core concepts of material processes, computational methods and digital fabrication techniques. Basic and advanced tutorials on computational design and analysis tools are provided. The programme performs as a team-based workshop promoting collaboration, research and ‘learning-by-experimentation’.
PART 2 – participants propose design interventions based on the skills and knowledge gained during phase 1 and supported by scaled study models and prototypes. The fabrication and assembly of a full-scale architectural intervention with the use of robotic fabrication techniques will then unify the design goals of the programme.

pproach that will hopefully work. There's still the last part of putting it all together, but I figured I'd post my progress so you could play around with it if you wanted. This is kind of a lucky situation since its only single face breps and simple trims that are being worked with.
I've attached 3 definitions to this post. The first is my reorganization of your original definition, which creates the surfaces from the point grid and culls out any surfaces that are not "on" the surface so that we don't have to deal with them later down the line. This is done through a small VB component which determines whether any of the corner points lie on the surface. If it does it keeps the surface, if not, then it doesn't. The only issue with this is that in your example file, there are some surfaces which the corner points do not lie on the surface, yet the surface that they create spans the underlying surface. At this point I'm not worrying about those. You mentioned that you only want the surfaces that lie at the edge...this can be done by testing whether all 4 corner points lie on the trimmed surface or not.
The second definition is a coded version of the project function. In the example it will project to all the breps supplied, yet in the final version this probably won't be desired. Also, the direction (z axis) is hard code...this could be swapped out if desired.
The third definition is an shot at trimming a surface with an input curve (that curve happens to be projected). I tried this many ways, but found that the function RhinoCutUpSurface seamed to work alright. The other attempts at doing this directly with through functions available for OnBrep were unsuccessful and very complex. Luckily because the underlying brep is an single, untrimmed surface this function works well for us, but in situations where we have a trimmed or multiface brep we'd be up a creek with out a paddle. The function creates an array of breps, but in our case it will create essentially the same surface split by our curve and joined together as a single brep with two (possibly more) faces. All we have to do is find out which face we want to keep and duplicate that into a separate brep and pass it out of the component. In the example file I'm determining which on to keep based off of the distance from a test point to the centroid of each face.
The other option here, which would trump the need for projection or trimming, would be to extrude the edge curves through the surface in question, and use the BrepSplit function which requires two breps. There would still be the need to sort out what to keep, but if this approach were used, all the split pieces would be separate breps.
So, all the pieces are pretty much working separately, all that I have left to do is put them all together in the base definition. The only thing that is really the hump with that is determining exactly which face to keep. My idea at the moment is to find out which corner of the surface does not like on the base surface and use that to determine which face will be thrown out. This might be one of the easier ways, but will not be rock solid. The other option is to pull a test point that's on one of the faces to the base surface and the other face, then use the distance from test point to the point on the base surface and the distance to the pulled point on the other face to the base surface to figure out which one to keep.
As to sectioning off parts of the solution, you could do this in a number of ways, but here's two simple ones. In a scripting component just add a boolean value to the inputs and put the whole script inside of an if statement that looks at that boolean value. With components just add a boolean gate or a null pattern componet anywhere you want in the stream. Again, hook in a boolean toggle value, and that will stop the info from going to components that are downstream.…
