algorithmic modeling for Rhino
Boolean Bug
Please check this:
Draw a triangle and offset inwards for some distance. Then use either Region Difference or Solid Difference to get the subtracted result of their extruded geometry.
What happens is that it looks correct in GH until this geometry is baked. When baked to Rhino its upper surface becomes untrimmed again and the opening is gone.
See the attached image and you can try this on your own. If this is a bug please fix it because I'm using this as part of my current project for work...Appreciate it!

This is a bug in Rhino itself not Grasshopper's baking. The geometry is correct but the rendering mesh is not. Play around with the mesh settings in Rhino I think un-ticking simple planes cures it. (I could be wrong)

Thank you! So I suppose if I export this it will also be correct using other programs? Say for 3D print?
