It would be nice to be able to create wall styles. Revit and Architectural Desktop have had these for years.
Currently the wall command simply draws 2 lines in top view.
An example of a wall style would be a brick cavity wall complete with brick hatching. Another would be a timber framed wall with studs and separate linings for interior and exterior.
It would take the form of selecting the wall command as is current but a drop down menu showing a list of preset wall styles.
It should include the ability to create custom styles.
