A problem about HB Shade

Hi,everyone,I have met a problem when I tried to create a shade.The problem is as fallows When the size of shade is less than 0.015 m. But my research requires me to create a smaller shade. Is there any way to solve it? Thanks very much.
“1. Solution exception:There must be at least 3 vertices for a Face3D boundary. Got 2”


Try checking the tolerance value in Rhino-Units.
Then recompute the GH.

Hi,friend,thank you very much.This method is very useful.Hope you have a good day.
