Idea logged by Autodesk Customer Support for German customer Ladislaus Wichert:
When dimensioning a wall, wall openings can be included in the dimension line with the openings height and width parameter.
Doors and windows have however more parameters related to their dimensions. There are rough height and width parameters in window/door families in order to specify raw building dimensions of the construction.
Please, enable Revit users to specify which parameters should be read by the dimension lines regarding wall openings.
Please, also enable to display those dimensions with a prefix or suffix.
