Nice story of perseverance and very well embellished by Stalinist propaganda :lol:

And now? Is there also a solution to my problem of wanting to display all edges rounded, as asked in the first post?

My comment to "Lokomofeile" was meant more in a way of senseless work regarding the "C" piece.

Sure, you can get those 90° chamfer corners with a metal file, but you shouldn't. Not if you want to crank out a couple thousand pieces for 0,15€ each in a short amount of time with the same predictable quality. You mill the chamfers and don't touch it afterwards, except for packaging.

There are many uses for 3D design files, and FreeCAD does not care or know why one needs a file.

The only part of FreeCAD that deals with machining is the Path WB. With proper knowledge and care one can create various tool operations. Whether those operations make sense or whether they are possible is up to the user to decide.

FreeCAD is not your mother. :o

You want something like that?

If so you just need to do fillets in other order, ones you've done should be last, that which failed should be first, or do them all in one step.
Also if radius differ than not all combinations are allowed.

So we need to know the smallest diameter of the filleting/chamfering tool which defines the smallest radius for the cut-out edges/corners.

If the cout-out corners should stay quite sharp, I would do it like this:

Hello Batucada, greetings to the Community!
Well, there is no doubt that 3D modeling and practical realization in the workshop are two things "a little" different.
I wanted to try, without using the "Path" Wb, to simulate the machining of machine tools to create what has been designed / modeled with FC, the result in the animated gif.
A discreetly equipped workshop would have no problem.
