"I have a question related to the ColorBySlope command you attached here.  Is it possible to take the gradient you generate and use that to limit where, say, a curve (or set of curves) would be projected onto a surface?  For example, if you…"

"Thanks Andrew, that works very well.  It is still a bit mysterious to me since I have not worked much with sets at this level, but I see what the definition is doing in principle.  I'll have to study it more!  Thanks again for…"

"You were on the right track. Here is my approach:   Get the center point of each face Project that center point back to the base surface, and get its UV coordinates Round off the UV coordinates to avoid slight inaccuracies use "Create…"

"Hi All, I though I would put this question back in the queue.  I have attached an updated definition in which I am trying to compare the overlapping surfaces with a shared XYZ point (similar to using the centroid for sorting duplicate…"

### Cull smaller (area) of two coplanar surfaces

Hi, I am trying to compare two coplanar surfaces based on area and cull the smaller of the surfaces.  The surfaces are shared walls of adjacent extruded cubes.  The cubes are extruded at varied heights.  I want to keep the larger wall between each cube and delete the smaller overlapping wall from the data structure.  If there are two surfaces of equal area, I want to cull one of them.  (In others words, I only want one wall between each cube cell.)  I want to do this because I plan to render…See More

"The ColourBySlope def has been very helpful. Is the output from the F(x) component in degrees (slope) or does the Z normal need to be converted into degrees?"

### Diva for Grasshopper

"Does anyone know how I could download DIVA v1.9 or later as referenced on the wiki?  I am only finding redirects to versions 1.1f or 1.2 beta.  The problem I am having is that when replacing the grasshopper component for the latest…"

"Hi, I have just installed DIVA and I'm noticing that I have a different toolbar for DIVA in grasshopper than the one shown in Jeff's install tutorial video.  My DIVA toolbar for grasshopper only has the "Analysis" and…"

### DIVA for Rhino

DIVA-for-Rhino is a plugin which runs thermal, daylight, solar radiation, and glare simulations. Our goal is to bring validated environmental simulations directly to the conceptual design environments of Rhino and Grasshopper.See More

"Danny and David, Thanks for your replies. Both of these definitions are very helpful (and increased my understanding of angle and area functions). Cheers, Matthew"

"Attached two files, one for assigning colours based on slope, the other for removing facets based on slope. I also changed your slope calculation to work directly on the z-component of the facet normal vector. I operate on the Absolute of the…"
