arches
(A door.) Location: 04 Masonry

Make it Flat or not. If it's arched, you can set either the Spring Height or the Arch Height, and the other dimension will change to maintain the overall height.

You can show Joint Lines representing the stones, and set a Stone Max Width. The lines use the Joint Pen. (The lines on the old arch broke in AC10.)

Turn the keystone off by setting the Keystone Height to zero. The Key Base Width controls the width of the keystone. (At this time, the flat arch can't have a keystone.)

Jambs of two arches
Plan: The nice thing about this arch is that it can show a proper jamb in plan, using the Plan Veneer Thickness. You can set the Fill and the Separator Pen (for the line between the jamb fill and the wall proper). The background color of the fill comes from the wall.

The overhead lines (Cased Op Lines) can be switched off individually.
