Set drawer-fascia reductions
Shrink drawer fascias from the drawer's construction settings and create gaps next to fillers.
Drawer fascias can be shrunk from the drawer's construction settings: select the drawer and, in its Construction tab, use Reduction > Side with its Left, Right, Top and Bottom values, which accept a number or a formula; a positive value reduces that side of the drawer front.
Drawer reductions, however, must be applied individually rather than in bulk.
To create a gap between a drawer fascia and a filler, you can also use the drawer system's Left / Right Filler Gap, found under Construction > Left / Right Filler > Properties & Panel Visibility, which sets the gap between the filler and the drawers.
For drawer fascias, the reduction value entered for each side is taken off that side of the drawer front, so entering 1 mm on the left and 1 mm on the right reduces the drawer front by 1 mm on each of those sides.
