Could you explain this is a bit more detail?
To elaborate on my problem - the object I'm working on is a STL file of an organ (image below). To implement the kinematic constraint I can need to give certain displacement constraints at a few nodes. These nodes are located depending on the way the mesh is created. Since I can only select nodes on the surface of the object - the likely hood that the points would form a 90-degree L-shape (rules of kinematic constraint) is highly unlikely. I tried to use the "skin surface" option on SpaceClaim to get split the entire object into 2 halves based on the lines drawn but no luck there (see image 2 - the lines are perpendicular and almost meet at the surface of the organ)
Is it possible to create a few points/nodes on the surface of the object about which the mesh is created?
