You hit it, spot on.
Most of my drawing is done in the early development phase, the phase where the drawing itself is a jumble of assembly and part views, cross sections etc; when shapes, sizes and distances are not yet fully defined and often need tweeking by 0.1mm or so (I develop small machinery, largest part sofar is a 'gripper rail' measuring 17mm dia, 84mm long; M3 is a BIG
screw to use, M4 is already humongous).
I know, this sort of tweaking is easy enough with the command line (mv @0.1,0 and the like) but I like to drag stuff to see if it really fits there (not to mention use the snap functionality).
Since the shape is not yet fully defined there is no block to move, and selecting objects can be quite tedious with all the zooming back and forth. And in complete accordance with Murphy's Law you tend to forget one or two of them...
Once I get the jumble to look and fit right I start exporting bits and pieces to the individual drawings for the manufacturing of the parts, that's where the final dimensioning takes place.
Only after that I create the correct assembly drawings (that to some extent look just like the jumble I started with
) and material lists...
