I know that there will be a better way than this, but I like to throw out ideas to see if it will inspire other ideas.
(Plus I think someone might be able to do a macro for this . . .)
My thought is to pick/create a plane to use to "slice" the part, duplicate the plane for your set interval -
Use Split Line (Intersect) to use the planes to get "profiles" from the stl-files, and grab your information from the split lines.
Just trying to give others some ideas . . .
