The Floor Corner Drawer 2 cabinet has a left and right internal End which fit at an angle between the carcass Ends and Back.
A V groove is placed in the Ends and Back to slot in the internal Ends instead of cutting off their corners..
The ability to control the presence of the V grooves in the inside of the carcass Backs is now independently controllable from the carcass Ends.


The following shows the Top of the cabinet in Machining Editor mode where each Slot is shown in green (i.e. DXF Colour 3)
