Changing the Horizontal Direction of a Spiral or U-Shaped Stair

Use this procedure to change the orientation of a spiral stair.
1 Select a spiral or U-shaped stair.
2 Specify the horizontal orientation of the stair:
If you want to
draw the spiral or U-shaped stair in a counterclockwise
direction
draw the spiral or U-shaped stair in a clockwise direction
NOTE This is equivalent to selecting the Flip grip that mirrors the stair around its start point.

Changing the Constraints of a Spiral Stair

Use this procedure to control what constrains the spiral stair by specifying the total degrees or the number of degrees
per tread to use. These fields are available only when you select a spiral-shaped stair to modify.
1 Select a spiral stair.
2 Specify the arc constraint:
If you want to
display the spiral stair with no constraint
