Analyze the individual sections of every sides.

[NiRu-hub]

Hi,

I am new to trimesh and just a beginner with it. I have a problem where I have an stl object and i would like to analyze individual section of the parts and slice / crop them in 3D. For ex: 3D object of a car door panel and i would like to slice only the part where there is nuts / bolts in them. I have couple of questions related to that please.

1. Is there any direct / easy method to analyze every sides and their individual sections of the panel after applying the mesh ?
2. How to crop / slice the portion on each section of the sides, where there is a screw & nuts

Regards,
Rudy
