As residential houses, apartments and commercial buildings can be constructed in multiple floors, the program provides the function to add and edit multiple layers.

 

To Add New Layer: right-click over the Main Floor tab at the bottom of the program window, select Add Layer, and then enter the new layer name, check on “Is the layer visible to other layer(s)” if you want to view the grayed out room shapes of this layer from other layers.

 

 

 

Switch between Layers: Click on the new Second Floor tab to switch to the layer. One may view the grayed out rooms of the first Main Floor layer. Now you may start drawing the rooms into this layer.

 

 

Edit the Layers: Right-click over the tab, select Edit Layer

 

Delete Layer: First, switch to a layer other than the one to be deleted, and then right-click over the one to be deleted, select Delete Layer.
