Show All Floors
Displays all floors on the selected 2D view.
Show Active Floor
Displays the active floor on the selected 2D view. The active floor, or "input floor", is the floor highlighted on the 2D Plan Filter.
Add Walls
Opens the Create New Floor dialog, which gives you the following options:
Click on the down-arrow on the Floor drop-down list. Select a floor from which to copy walls. Use the radio-buttons to choose whether you want to copy all walls, perimeter walls, or perimeter walls with a user-defined offset (type the offset in the "Overhang offset" text box).
You can also make an exact copy of the selected floor, including spaces, windows, and shades.
When copying perimeter walls, you have the option to merge walls (checkbox). If a wall is intersected by another wall then a node, or wall divide, is added at the point of intersection. When copying only the perimeter walls, any divides can be deleted or merged, provided the same building element exists either side of the divide.
The Add Walls button is greyed out for those floors that already contain walls.
Click on the down-arrow on the title bar to open a context menu and select "Auto Hide" or "Hide".
