I have some Structural Columns which I have joined to walls (12mm Plaster - 100mm Concrete Block - 12mm Plaster). This shows the walls cut out to correctly show the structural column.
When I place a door into the wall the wall plan changes to show 12mm plaster - 50mm Concrete Block - 62mm plaster.
Any ideas?
