[cgma-dev] Facet/Cholla engine

[David Thompson]

Hi Jane,

> ... Other than sending facet group separately to make individual surfaces, I understand it's the most accurate approach, can you try to give an feature_angle and set split_surfaces=true to see if, first of all, it gives 4 surfaces?

I tried using feature_angle+split_surfaces but always get a single surface back.

	Thanks,
	David

Among other things, I need to attach attributes (ToolData) to portions of a shell, not an entire shell at a time. Is there another way to do that?
