Stair

You can create straight stairs, curved stairs, long stairs, stairs with a lot of steps, wide stairs, and stairs without side polygons.

You can customize the shape of your stairs with these shape properties:

Property:	Description:
Steps	Set the number of steps to define on the stairs. The default value is 6. Valid values range from 2 to 64.
Build Sides	Enable this option to draw polygons on the sides of the stairs. This is enabled by default. You can disable this option if the sides of your stairs are not visible to the camera (for example, if your stairs are built into a wall).
Curvature	Set the degree of curvature on the stairs in degrees, where 0 makes straight stairs and 360 makes stairs in a complete circle. Keep in mind that you might need to increase the number of stairs to compensate as you increase this value. The default value is 0. Valid values range from 0 to 360.
Width or X	Set the width (dimensions in the x-axis) of the stairs in meters. You can use the Width slider or enter an exact value in the X text box. The default value is 2. Valid values range from 0.01 to 10.
Height or Y	Set the height (dimensions in the y-axis) of the stairs in meters. You can use the Height slider or enter an exact value in the Y text box. The default value is 2.5. Keep in mind that you may need to increase the number of stairs to compensate as you increase this value. Valid values range from 0.01 to 10.
Depth or Z	Set the depth (dimensions in the z-axis) of the stairs in meters. You can use the Depth slider or enter an exact value in the Z text box. Keep in mind that you may need to increase the number of stairs to compensate as you increase this value. The default value is 4. Valid values range from 0.01 to 10.
