As demonstrated in the attached video, I had to use the line tool and draw a 2d rectangle, then right click on it to intersect faces, then make one side of the ‘split’ object a group, and then move that new group aside.
Repeat the first few steps again, then newly created split group is deleted, since I wanted to make the corner brace 1mm shorter (10mm scaled). To do the opposite (e.g. extra 5mm), it seems I would select the move tool, then do ctrl c, then use the mouse to move it up.
Edit: there’s no need to redraw the 2d rectangle, just use the move tool, and move it down the desired amount.
Scaling is not an option since the hole size would change, and so would the ‘thickness’ of the corner brace.
Also, is it possible to reposition or resize the hole on the brace, without the deleting the old one? I’d appreciate a demonstration if possible.
Edit: Yes it possible to do both, the scale tool seemed to work, and the move tool, after highlight the circle/hole area.
