I would like to be able to create sketch blocks within a drawing, the reason being that I often create complete rooms of fitted joinery and need to show room doors and windows drawn by a different company. Being able to copy and paste from their AutoCAD drawings and then convert the pasted geometry into a sketch block would make it a lot easier to constrain the door or window to the drawing without altering the door or window itself. As an example the current room door I'm trying to accurately position so I can dimension to it has 5000 constraints missing making it tough to constrain into position without altering its original profiles.
