A2Plus: Simple fusion using imported Cubes fails (to recompute)

[drmacro]

I do not understand how it helps to overcome the error of the "fusion"-command, if the shapes are imported by A2Plus.
A2Plus-hierarchy is creating the headaches.

That was what I was getting at earlier.

An assembly workbench is not a modelling tool (i.e. for cutting with imported solids).

The assembly workbenches are for assembling completed components.

Typically, you'd use link to the cutting objects.

Got it ... what a pity, because the modelling works regarding cutout/drill-holes and meet my (wrong) expectations nicely.

Hmmm ... maybe the import itself is the issue (https://forum.freecadweb.org/viewtopic. ... 70#p534370).
Do you know where the enums are defined?
The test in the CPP against a magic 33 is somehow surprising.

I'm still fighting for a solution.

Regarding mount/import/assembly/<your_modelling_operation> ... it is a chick-egg-issue.
The new drill hole positons (holes/cut-out) can be made just after the object(s) has been placed on the baseplate and the locations for the fasteners are given. I do not see a possibility to work other way around.
