Building Worlds
• Visible in Wireframe Views to show the object after you create it. (See “Showing and
hiding objects” on page 38.)
• Hide in Browser View to create a hidden object, such as a hidden luminous object. (See
“Creating hidden luminous objects” on page 54.)
• Locked to lock the object. (See “Locking objects” on page 37.)
• Subtractive to use the object to cut through another object. (See “Creating openings in
objects” on page 26.)
• Thickness to specify the thickness of the slab in feet.
3 Click in the document window. If you’re working in Top view or Isometric view, click
where you want to locate the center of the slab edge. If you’re working in Side view, click
where you want to locate the midpoint of the slab thickness (or height). Hold down the
mouse button and drag to reposition the object.
To change the slope of a slab:
1 Select Side view. Although you can change the slope in Isometric view, the slope of the
slab is easier to see if you work in Side view.
2 Select the select tool ().
3 Do one of the following:
• Select the connectors on the side of the slab that you want to adjust. Drag the connectors
up or down to the desired elevation. For information on selecting multiple connectors, see
“Using the select tools” on page 30.
• If the slab is connected to another object, such as a wall, drag that object up or down.
Note: Depending on the position of its connectors, a slab can become non-planar. (A non-
planar slab is one in which no single plane can be positioned through all of its connectors.) In
this case, Atmosphere automatically breaks the slab into two triangular slabs. If the slab
becomes planar again, the break is automatically removed and a single planar slab is restored.
