title: Calculating thickness of 3D geometry of a model
body: <p>I am doing finite element modelling. I have a geometry which does not have a uniform thickness and I want to calculate the thickness of that in 4 distinct nodes and compare it with another model. Is there any method to calculate the thickness of the 3D model? (the 3D model can be exported in the format of .stl,.obj,.wrl,.feb.geo and some other formats )</p>
