Many firms use the curtain wall tool to model storefronts. These generally have a corner post rather than a diagonal frame.
When using the polygon method to create a Curtain Wall which turns a corner, graphically in 2D and the 3D the representation is not what you expect. This occurs at both the top and bottom where the boundary frame meets the corner frame and by default cuts at 45 degrees. The workaround is extensive.
You have to do this one by one in Edit mode: Select one of the affected boundary frames and navigate to Cutting Planes and change the Cutting Plane from Automatic to Manual. This will change the cut end to 90 degrees. If it changes the wrong end, you have to undo and change Cutting at Top to Cutting at Bottom or vice versa. After this you still have to stretch the elements to the edge of the post - which only has a node in the center, so guidelines are needed to do this accurately.
You should be given the option kn the Scheme Settings to make the default cut 90 degrees - or even better - have a "post" option instead of a corner frame, with an associated 90 degree cut.
