I Can't find this anywhere in LibreCAD (2.1.3 or 2.2.0(124)):
Are "Smart Dimensions" included in the current release or planned for a future release?
By "Smart Dimensions" I mean the dimensioning of objects by selection of an edge; this instantly generates a dimension line parallel to the edge, much the same as a diameter or radius is generated by selecting a circle, rather than having to select the two endpoints of an edge with the horizontal, vertical or aligned tool.
I would also really like to see 'Smart Dimensions' or something similar implemented in LibreCAD. It is one of the best features of Solidworks and really speeds up the drawing process. For those unfamiliar with it, the big advantage over 'the ordinary way' of dimensioning is that you can go back at any time after object creation and edit the dimension, and the object size will change accordingly without having to delete the object and redraw.
