"I made some functional changes to the file and override the ClearData() method. It's all untested.  I also made some syntactic changes that reflect my own personal programming mantras. You do not have to subscribe to the same set of rules…"

David Rutten replied to Martin Manegold's discussion Custom Component Custom Preview stays when disabeling the component
"I think the problem is that the input is disconnected but it's not an optional input. Grasshopper will not even call the SolveInstance method in this case which means you never erase your display caches. The best place to erase your caches is…"

Andrew Heumann replied to Martin Manegold's discussion Boolean Difference Doesn't work
"It would be helpful to see your grasshopper document with the script to troubleshoot. When I use the following script:  private void RunScript(Brep x, Brep y, ref object A) { A = Brep.CreateBooleanDifference(x, y, 0.1); } The boolean is created…"

David Rutten replied to Martin Manegold's discussion Creating Lightweight Extrusions
"Grasshopper currently has no native datatype for extrusions. I've been meaning to add this secretly to the Brep parameter as extrusions are primarily a memory/computational optimization, not so much a user feature. However I haven't looked…"

Negative Index in Mesh Ray Intersection Result

Hi Everyone,while DebugingRhino.Geometry.Intersect.Intersection.MeshRay(BaseMesh, ray, out faceIndicies);I got a result I didn't understand. How can a Face Index be negative? Later in the Code I get an exception when trying to retrieve the face byBaseMesh.Faces[index](With "index" being -1)Thanks- MartinSee More
