Position/Positioning of cursor/marker on object

1. A concise explanation of the problem you’re experiencing.

I’m discussing if it is a possibility to set a marker/cursor on an object - so I would not change the view, but I would like to move the cursor/marker in the model/scene.

Any experience/ideas ?
