Newbie at blender - I am an anthropologist working on my dissertation. Seeking someone to help me develop a reliable (read: CONSISTENT) way to find the volume of this incomplete space on the distal femur. The space I reference is between the two round parts called condyles. I have tried this by making a convex hull, and through various means solidifying it & finding the volume of that object on Meshmixer but get different numbers each time I repeat this on the same 3D model. Unsure if I need to add an edge detection method or something. Can anyone help me with a more reliable method? Will give authorship credit on ALL future publications utilizing your method(s). I can provide .obj file(s) upon request. TIA
Edit - in regards to where the notch/fossa parameters are: there is a ridge along the inside of each condyle and the upper and lower aspect that I have attempted to outline. What I was hoping was there might be some way to have Blender fill in a mesh within this loop (similar to the grid fill function) that I might be able to get it to project points downwards to the actual bone scan which I then could solidify and take the volume of. However, I am not sure if this could feasibly work in Blender or if this is even feasible.
