Lets say that in the draft workbench I create a rectangle wire and I draw a circle wire in its center.
Is there a way that I can extrude both in a similar way to sketching so that the circle gets interpreted as a hole?
I came across the post of someone that selecting both wires, upgrading (creating a compound) and extruding would do that, but it doesn't, it instead extrudes both as solids.

Why don't you do it in Sketcher?

Re: Extruding Multiple Wires Together
To be entirely honest, the fact that I have to be adding tens of constraints every time seems problematic to me.
I totally understand the benefits of it but it's time consuming.

Re: Extruding Multiple Wires Together
So don't add constraints.
Your model won't be parametric...but, then it won't be in Draft workbench either.

Re: Extruding Multiple Wires Together
I don't know what you want to model, but precision takes its time. Either by using such things as constraints or by doing some math outside of FreeCAD.

Re: Extruding Multiple Wires Together
I am coming from code-based CAD tools where making designs parametric was a piece of cake, so I am exploring my options for different use cases.
Re: Extruding Multiple Wires Together
extrusions are done per face,
so if you make your rectangle and circle with the property "make face" set to true it becomes quite clear why fc does 2 extrusions from the compound (even more clear if you downgrade that compound).
now the question is, how does one make a face with a hole in it?
2 different ways:
draft/rectangle + draft/circle -> part/cut
draft/rectangle + draft/circle -> draft/upgrade (now a compound) -> part/bool xor
ps: when you are tinkering around in draft you are at the same time automatically learning a bit of the lower levels of fc, and how things work in terms of building different geometries, that learning will always be useful also somewhere else - so keep going your own way - but there might be a time when you yourself come to the conclusion that doing this in sketcher is best for you - but then at least it is your own finding, and not someone else's.
