A questions about project()

@z3dev
When I use project() to try to project the .stl model onto a 2d plane, the console prompts:

But the 3d model can be displayed normally.

This problem does not appear in all .stl models, only complex .stl models will appear in this problem.

I debugged and found that the cause of this problem was that poly3.toPoints() returned an empty array.

Should the empty array be filtered before calling poly3.toPoints()？

Ok, I have submitted an issue on github.

@jess-yan this could be a bug, but again many STL meshes are full of holes and incomplete.

It would be best to open a new issue at GitHub. And attach one of those ‘bad’ STL files.
