Hi.
Normally when you put up inside walls in groundplan module, you let them just connect to other walls. And then a inside wall that is standing perpendicular to another inside wall, will cut through the boards layers.
In this case, I wanted to let the gypsum boards (fibre gypsum) go through and the perpendicular wall will just be connected at the outside of the gypsum. So I adjusted the perpendicular walls to the outline of the first wall. The boards outline, was still split at the points of the perpendicular walls. Then I adjusted the perpendicular walls to 1 1nd then 2 mm from the first wall. The boards outline, was still split at the points of the perpendicular walls. Then I moved the first wall 10 mm away, then the boards outlines where not split. Then I can place my boards and move the wall 10 mm back again.
But why is it not enough to adjust the perpendicular walls to the outline of the first wall or to 1 or 2 mm away??
