FreeCAD to design moving parts

  • 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?


    If the user manual doesn't mention it, it's probably not a feature available in FreeCAD. You may have to consider some more powerful (not free) tool.

    Fusian 360 is free for most use cases and includes moving joints as well as animations of those joints.

    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.


    Because... links die, but content typed in here will be archived and searchable.

    I suppose that's as far as I can get with FreeCAD... Not as comfortable as in Blender, but kinda solves the task :

    The link says that three different clicks are required (center point, reference point and rotation point - 5 steps in all). Whilst you do give the main overview, I think that (maybe in this case), a full reproduction of the five steps could be more useful :-) Admittedly, the video may be harder to explain in text (but it probably is doable)
