There is a separate Stairs Extension that contains tools for drawing stairs, landings, and railings of different sorts. Downloading and installing this Extension will add two separate component tabs to CET Designer: Commercial Stairs with components suitable for office and home environments, and Industrial Stairs with stairs for industry and storage sectors.
Items from the Commercial Stairs tab Items from the Industrial Stairs tab
For both categories, you can either insert custom stairs or stairs that follow building code standards, such as IBC, OSHA, and ISO.
To use these components, simply left click on one and release the mouse button. Then move the cursor to the drawing area and click to place the the component. During placement, a green properties box appears where you can edit settings. You can also select the stairs, landing, or railing after placement and edit settings in the green properties box. Altering these settings allows you to create stairs of different styles, with or without stringer. Here are some examples:
Railings are automatically added to Industrial Stairs that follow building codes while custom stairs place without railings.
Multiple stairs can be attached to the same side of a landing.
