When you insert a corner window, you can change the opening width measure from the Properties palette to:
- Inside of Opening. Measure the corner window from one wall end to the inside (shorter side) of the wall corner.
- Outside of Opening. Measure the corner window from one wall end to the outside (longer side) of the wall corner.
- Center of Opening. Measure the corner window from one wall end to the intersection of both walls at the wall corner.
