• To make the top and bottom steps a different width, drag each of the connectors at the
top or bottom step. Atmosphere Builder automatically adjusts the width of each step
between the top and bottom step.
To change the shape of a stairs object:
1 Select Top view or Isometric view. Although you can change the shape of a stairs object
in any view, a twisted shape is easier to see if you work in Top view or Isometric view.
2 Select the select tool ().
3 Select one connector at the end of the stairs object you want to twist.
4 Drag the selected connector in the direction you want to move it.
Combining objects
With the constructive solid geometry features in Atmosphere Builder, you can combine
two or more objects to create a new object. There are three modes for combining objects:
Union Creates a composite object. This is the default mode for combining objects.
Intersection Creates an object from the junction of two or more objects.
Subtraction Creates openings in objects.
Creating an object from a union
By selecting the Connect Objects option in the Tool Inspector palette, overlapping objects
can be combined to create a composite object. For example, you can combine a column,
cone, and floor object to create an airplane. The resulting object has a smooth surface, as
if a skin has been stretched over it.
Creating an object from an intersection
You can create a new object based on the intersecting area of two or more objects in a
group. You start by creating a composite object and grouping it together. Then, you select
the Junction option for the group. For example, you can create an elliptical-shaped object
by intersecting two columns.
