I am trying to create a mechanism with moving parts, and would like to see how it works (whether it even works) before printing it.

For example, there's a servo with a bracket, and I would like to see how far can the bracket move before colliding with other objects.

enter image description here

Unfortunately I cannot find any information on how to set pivot points and rotate objects around these points in FreeCAD. Is this even possible?

freeCad has a draft rotate function in DRAFT workbench:

  1. Select an object;
  2. Press the Draft Rotate button, then;
  3. Click to set the rotating point and rotate.

You will get used to that after a few trails.

There is a step by step guide on freeCad site.

There is also a short demo of the function here.

I would also like to take a look at the A2plus Workbench (Freecad Addon). There you can define constraints which can help with this problem. As far as I know, parts cannot be moved with the mouse pointer, but angle parameters can be entered.
