Indeed. Its not only a toy example, but something real and seems like real cases get difficult...straight line to link it to... but you have picked a somwhat difficult example
I played a bit with drawings. They are so to say a snapshot at a given time as far as i have seen. -> changing the 3d structure, the drawings will not follow.
It would be cool to have the process of drawing stored as process (project this object seen from there to 2D), which could later automatically be re-executed. If one would have then drawing internal linked dimensioning, everything could be really parametric...
Is there a way to project a body including the dimensions into a drawing?
I did not yet get my nonlinked linear dimension together with the body into the drawing...
