Size tandem drawers and box drawers
Let the tandem brand/model specification set the bottom and back panel sizes, and know where drawer depth is editable.
The bottom and back panel sizes of a tandem drawer are taken from the selected tandem brand/model's specification, so the designer does not need to enter or check them; this applies to internal tandems as well as standard tandems.

In box drawer construction the drawer depth is an editable value (Default Drawer Depth).

In normal construction the depth is taken from the wardrobe/system and is not freely set.

A channel or tandem item that declares its own depth can also fix the drawer depth.

When a tandem drawer system is applied to a drawer whose current construction does not match the tandem's requirement, the software shows a popup warning that the tandem requires a different drawer construction. Accepting the prompt automatically changes the size of the drawer's bottom and back panel to the dimensions defined in the hardware catalogue. This is why selecting the correct tandem model matters.
