"Hi Federico, the second material is a that for inactive elements which is added by default. If you plug a panel into the 'def. Model'-plug of the ModelView it tells you there are two models? Best, Clemens"

ModelView is doubling my geometries

HI, I am testing the deformations in a beam flat structure that is supported in 4 points near the center. I have been working with various BeamsIDs si I can distribute material properties differentially but I started getting 2 sets of beams when I use the ViewModel component. No I simplified my definition and I am only using one type of beam and one type of material and I still get this strange error. I tried flattening the list of support points to no avail. As you can see on the screenshot, I…See More

CurveBrepIntersect problem in GH Python

HISO I am trying to group a large set of polylines depending on if they intersect or not a section of a surface. I did manage to do this in rhino python succesfully but now I am trying to take the script to Grasshopper python. It seems that the command CurveBrepIntersect is insisting that ALL the polylines are always intersecting each section of the surface, which is wrong. From the grasshopper, one of my inputs is a list of untrimmed (or trimmed) breps (or Surfaces) and I intersect all the…See More

Grasshopper/Python data tree output with polylines

Hi,A couple of friends and I have been trying to output a nested list of geometries ( polylines) from the Grasshopper/python editor to grasshopper keeping the data structure. I know I have to work with GH_Path to create Data trees but the problem seems to be that the type of geometries dont match.I get this error:Runtime error (ArgumentTypeException): expected Polyline, got Guidevent though the GUID object comes from a rs.AddPolyline command.I have stated that the type of geometry in the GH…See More

"okay thanks for clarifying, so you applied different materials to every beam in the model for changing the e-modulus? i guess shells could also be handy for that of course. but a good approximation (and a faster one) also might be representing a…"
