AEC Window Header Height Properties Doesn't Work Correctly

#1
When I insert a new window into a wall, it inserts with a standard header height of 6'-8".

When I change the window height in the properties, the header adjusts down.

  • A. The header height is mutually exclusive from window height. When I change the window height, the header height should remain static.
  • B. I cannot edit the header height to correct this. If I enter in the original header height (or any other header height) into the header height property, it reverts back to the calculated header height after changing the window height property. The only way to change the header height is to drag a stretch handle in an isometric view.
