This is not really a problem but something interesting.
I launched PreForm (2.5) and loaded a couple stl’s. The pieces looked weird so I zoomed in and realized that the software is showing the laser path instead of the skin of the 3D model. I can’t find any information about this and seems that I can’t repeat it either. Unfortunately I don’t have screen grabs because at the moment I though it’s a new feature.
Your thoughts?
