Q: I have two identical floor plans, one for lighting and one for power. I inserted all my rooms on one of the floor plans. How do I insert them on the other?
A: Use the DM Electrical->Building Definition->Insert Room Outlines on this Drawing command.
If the floor plans are on the same drawing, use the DM Electrical->Alignment Points->Insert Alignment Point command to insert an alignment point and draw a box around the second floor plan.
