Wall Height

The default height of walls when creating building levels in the Structure Input form. Each newly-created level will have this height (not the height of the first level entered).

Wall display Thickness

This does not affect the design in any way; it is here to allow you to adjust the thickness of the walls that are displayed in Plan View. Using the actual wall thickness (4" – 6") usually results in a reasonably proportioned diagram.

Floor/Ceiling Depth

The default size of the floor joists (and flooring thickness) when creating building levels in the Structure Input form. Joist depth affects the elevation offset, which is entered in terms of joist depths, and the overall height of the building for wind and seismic load generation.

Note that the upper ceiling depth always defaults to zero, as it is rare for roof joists to be placed on top of ceiling rim boards. Make sure you set a value in Structure Input Form for the case of flat roofs.

Opening Height

The height of the very first opening in your project. Created by dragging the mouse in plan view. After that, openings will have the same height as the last one created. The opening heights can then be changed in the Opening Input Form.

Opening Bottom Offset

The distance from the bottom of the wall to the bottom of the very first opening in your project created by dragging the mouse in Plan View. After that, new openings will have the same dimensions as the last one created. The opening offsets can then be changed in the Opening Input Form. The bottom offset does not affect design.
