Hi Ben,

This is normal as the door in the middle has on both sides a shared panel edge with the left and right door. 

Let’s calculate.

You have a slack value of 1.5mm on the doors 

The doors cover the left and right side panels by 18-1.5 = 16.5mm. 

On the other side of these doors is the shared edge with the middle door. There, the cover value is 18/2 = 9 mm -1.5 slack = 7.5mm

For the middle door it is the same value on both sides. For the left and right doors, there is a value of 16.5 on the outside. So 16.5-7.5=9mm.

The door on the left and right side will be 9mm larger than the door in the middle. 

If you want to have equal doors, select all doors by holding down the ctrl and shift key. When selected, right-click and select ” equalize doors and drawers size”.

PolyBoard will now recalculate the position of the uprights to reach equal doors. The result here is that the panels will no longer be evenly spaced, but this is normal.

Regards
