Hi, Mr. Lasso! Sorry to reopen this question, I recently met the same problem. I have a head model and a bone model, I want to make the relative position of the two models in the 3D view same with the real world(The bone is tracked). This is my hierarchy in Slicer.

The main question of mine is how do I compute the

`F4ToTool`

transform?(The “F4” is a bone model and I have its 3D model in real world.)
How do I collect points? I use the `StylusTipToStylus`

Transform point to the markpoint on the bone in the real world and click "place ‘from’ ", then mark the corresponding points on the bone model in Slicer, but the computed transform is not right for me. I also use the same method but the real world points is the “To” list, it is also not work for me.

Could you give me some detailed guidance? Really Thanks!

If what I ask is not clear, please let me know.
