Note: when placing a window or a door with a preset, hover the element over the Arch Wall, and wait for the element to rotate so that it is parallel to that wall. Aim for the bottom edge of the wall, and use the Sill height
to adjust the distance from the floor. If this is difficult, use the Draft Near snapping mode of the Draft Snap toolbar to insert the element anywhere on the face of the wall, and then adjust its DataPosition manually as described above. Having many Draft Snap modes active at the same time may cause issues with placing the element, so try with only one option at a time.
