Hi!

I have just started on using FreeCAD, I am really liking what I have seen so far!

I have some prior experience in 3D CAD (learned Solidworks and autoCAD over 25 years ago), so I think I understand the basics, but I have some trouble understanding how I should go about to model my project.

I am trying to model a slightly fancier version of a screwdriver holder, like this.

In Part design have modeled the 'slot' for a single screwdriver. I used the diameter of the screwdriver shaft as a base for the other parameters. So if I increase the diameter, the related dimension change accordingly. So far no issues.

My thinking was, as a second step, to create a base cube and substract the slots for each screwdriver (with various diameters and heights) from this.

I am not sure how to do this. Is this even possible? Or am I trying to do things in the wrong order?

Any help to get me in the right direction would be greatly appreciated! I am not too lazy to read documenation, but for now I don't know where to start!
