How can I make a diamond shaped window - essentially a square window turned 90 degrees? There is no turn handle on windows. In the Transform/Replicate tool Rotate is grayed out when in a window. If I open it and go to shape or arch there is no arch that is applicable and in shape there's no way to rotate it either. I can't find a diamond window in Andersen or Marvin or in the Chief Architect Library. I know there has got to be a way and I'm sure it is simple and staring me in the face. Than
