One line devices, including panels, are treated differently than other devices in Design Master Electrical. It is possible to insert them on more than one drawing. This feature is typically used to show them on the lighting and power plans.
If you have inserted the panel on one drawing, you can use the DM Electrical->One Line Devices->Insert Plan View Blocks in Another Area or Drawing command to insert them in the other drawing.
Once you have done this, if you move the panel on one drawing, it will automatically move on the other drawing. It is important that the alignment point be in the same relative location on both drawings. Otherwise, it will appear that the panel is being move to the wrong location by our software. If this is the case, moving the alignment point in one of the drawings typically will solve the problem.
If you want to remove the panel from one drawing and place it on another, erase it from the first and insert it on the other. When you erase the panel, it will remove it from the drawing but not from the database. This is different from other types of devices, where erasing it from the drawing removes it from the database.
It is not possible to copy-and-paste panels. Instead, you will want to use one of the two methods described above to duplicate the panel on a second drawing.
