This is a new idea for AutoCAD but it happens a lot working in Civil 3D: my drawing is being regenetated a lot of times, for example if I have to select an assembly in a particular area of the model space to assign it to a corridor region.
I mean, i have to zoom IN and zoom OUT to select objects.
This is the cause why the drawing is regenerating continuosly.
Please, add a system var to show it in the OPTIONS dialog box, to enable/disable auto Regen. In fact, we could have a auto-Regen timer to call the command Regen, similar than the auto-save document timer.
I don't know if we can lock the area in the model space to apply zoom IN and OUT.
