When I draw a box ( 130 cm width) and make the top overlap to the left and right by 2 cm polyboard 6 will keep its overall width 130 cm.
if I open this cabinet on polyboard 7 , it will automatically switch to 134 overall widths.
I found that, if I change the external zones to outer this problem will be solved. but I do have a lot of files from polyboard 6, can i make the default external zone outer? or is there any other option?
