Have you have inserted a series of members, as an example joists, and then need to make all of them longer or shorter? Select one of them, then right click and select Select All Similar, to select all joists, now right click again and select Lengthen to Fence. Left click twice to draw a line where you want the members to now end. The members will lengthen or shorten to that new point. Hope that makes your Envisioneer work, one step easier!
