And thanks again, @thomas-neemann : here is a suggestion https://www.youtube.com/watch?v=5jGeNHqmi-o Ah, nice - the technique with "3D diagonals" at both reference object, and target compound, and aligning versus the centers of those lines, should work fine for rectangular shapes! Many tha...

Many thanks, @Roy_043: For a parametric solution use this expression for the Position of the Compound: Box.Shape.CenterOfGravity - .Shape.CenterOfGravity + .Placement.Base See Expressions for more information. Excellent, thanks a lot; that seems to work fine - I was a bit puzzled where the expressio...

Many thanks, @thomas-neemann: I would do it this way https://www.youtube.com/watch?v=k2kVe4SCcEU Pretty neat, thanks! Since the GUI in the video is in German, I'll try to rewrite the procedure here: Open Arch workbench Click on the Line tool Draw a "diagonal" line from one extreme point (o...

Many thanks @wmayer: In order to remove an object tmp. from the document you must open a transaction, remove the object(s) and commit the transaction. After having saved the document just call undo. ... But you must be care between opening and undoing a transaction not to call any other function tha...

Many thanks, @wmayer: The easiest would be: Gui.runCommand("Std_Copy") Gui.runCommand("Std_Cut") Gui.runCommand("Std_Paste") .... that is what I was looking for! :) EDIT: Note that in either of these cases, the calls to Copy/Cut/Paste are asynchronous, that is, calls li...

I really hope there is something better than the approach I'll list below - if there is, I'd love to hear about it. I just realized, it is possible to do copy/paste in FreeCAD Python, - by emulating keypresses with PySide (see also https://www.freecadweb.org/wiki/PySide_Advanced_Examples ) - here so...
