When you create a device on a schematic drawing in connectCAD you can already add information about the physical piece of equipment it represents.
One simple menu command Update Layout adds any new device to the rack elevation layer where you can set up the actual locations of equipment in the real world.
We model physical equipment in connectCAD using the EquipItem smart object. On floor plans EquipItem is a true 3D object that you can position precisely within your model. While on the Rack Elevation layer it draws in 2D front view for easy drag-drop positioning. It "knows" where it is in relation to rooms, rack and rack frames feeding that information back to the schematic layer as you move it around. EquipItem displays its name and make/model data regardless of size and shape.
It just works.
