Parametric doors and windows

[3dfever]

It would be great to have a parametric door and window creation tool where libraries of common door and window types could be modified.  This would include: frame types that retain the ability to automatically extend to the opposite wall surface, libraries of interior and exterior casing profiles, sill profiles, sash frame dimensions, vertical and horizontal muntins counts, offsets, etc - all elements with dimension inputs.  Best if diagrams could clearly illustrate which part of the window/door component is being prompted for dimensional input. Perhaps someone has already produced an extension or script for this but I cannot find.  Any thoughts welcome!
