Use the Stair command (StairAdd) to create Straight, Multi-landing, Ushaped, U-shaped Winder, and Spiral stairs.
Create a stair tower in a project and a custom stair.
Constrain the number of risers, tread size, riser size, and run of a stair
using Calculation Rules.
Edit the style, shape, turn type, width, height, and justification to create
stairs.
Identify the purpose of grips located on various stair shapes.
Create, edit, import, and export stair and railing styles using the Style
Manager or Content Browser.
Control the visibility of the lower or upper portions of stairs using the
display properties.
Modify the stair edge with the following Customize Edge options: Offset,
Project, Remove Customization, and Generate Polyline.
Anchor an isolated stair to a stair landing and anchor a railing to an AEC
object.
Use the Railing command (RailingAdd) to create railings that are
freestanding, attached to stairs, and attached to stair flights.
Create railing styles.
Creating a Stair Construct
• Create the stair in a construct drawing that
spans multiple levels
• Attach floor plans as reference to the stair
construct
• Stair is displayed in the view drawings for each
floor served by the stair
• Create the stair construct drawing in the Project
Navigator
