Dynamic window component that reports back a tag right into LayOut. Tolerance must be set to 1" increments to report back a clean tag. If your rough opening is not modeled to a clean dimension, the window will resize itself based on the tolerance. By default the tolderance is set to the max of .0000001, so it will snap to any opening. If your opening is not a clean round dimension, the tag will not work. It's best to model your rough openings to clean dimensions, then snap your window to 1" tolerances, to adhere to standard window sizes.
