STRETCH in 3D
I find it hard to believe there's no Stretch-like possibility in 3D Brics.
In 2D I can select ends (or grips) of any number of elements by leftward-box, hit STRETCH - and stretch (or shrink) the ends of all those elements in any desired direction, without altering the topology of the drawing.
Can't that happen in 3D? For example a window - can't I leftward-box to enclose the top ends of the window's verticals, and the whole of its top horizontal, and STRETCH (or similar) to make the window 100mm taller but topology unchanged?
I can do it by selecting all the faces that would be moved complete, one by one, then DMMOVE. I guess what I'm after is to select a whole bunch of such faces by rightward box, instead of one by one.
If not, why is it technically impossible, and what's the recommended way to achieve that? Please don't say 'make everything parametric!
