> “Thickness” is not a very well defined term for models (surface meshes), but for shell-like meshes it is probably not too difficult to estimate it robustly and accurately. Potential approaches: A. Extract medial surface and estimate thickness as 2x of distance from medial surface. There are various ways of computing these in Slicer. One possible workflow: Compute medial surface using Simple Filters module - BinaryThinningImageFilter. Compute distance map using Simple Filters module - Daniels…
