Wall appears behind window in the Drawing View how to prevent the wall from showing?
Adjust the window's sense distance. The default is 1.0 but this value can be decreased so that anything beyond that point wont be visible, in this case the wall behind the windows.
If this refers to a wall being visible behind GLASS in a window in a FACADE I think it is a bad solution you are suggesting.
Glass should have a degree of transparency in renderings, but NOT in facades on drawings.
Unfortunately the delivered dataset has seeds for sections and facades with Display Styles with TRANSPARENCY THRESHOLD ticked. This means that elements with glass Part becomes transparent in drawings - which they should not be.
Untick TRANSPARENCY THRESHOLD in the seed Display Style - and you are done for as long as you use that Dataset.
