Window sill appearance in elevation

[Scott Newland]

I am using a standard ArchiCAD Library 14 window (W1 Casement 14) and am getting inconsistent results between the plan and elevation. I've set the exterior casing to 2-1/2" wide, but I can't get the sill overhangs to extend to or beyond this. Oddly, it shows up fine in the plan view, but the elevation shows the sill short of the casing on each side. In the dialog box, the Sill Overhang boxes are greyed out at 2". I can't seem to access them to increase the number to, say 3".

You have placed this window in a brick veneer wall. Turn ON the BRICK SILL option then the grayed out side dimensions will be available.
