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…

Creating a 3D modelled "mold over" an imported object

Let's say I've made a 3D scan of my face and managed to get that into FreeCAD. How might I then create an object (it's a mask, okay?) that conforms to the shape of my face, with a given thickness, such that I can export and 3D-print that part…

OpenSCAD / FreeCAD splitting, hollowing and threading model

I had a thought the other day that it's 100 % waste to have either a solid or hollow 3D-printed model in relation to utilizing the space inside of it for different modules, e.g. secret compartments, modules like salt/pepper shakers, etc. So I…

FreeCAD: Scene doesn't look 3D

I finished a 3D object for 4 wheels, but something seems wrong with the final scene to me: The nearer wheels (#1 and #2) appear smaller than the far one (#3 and #4), and the distance between wheel #3 an #4 seems longer than between (1) and (2), like…
