Objectives

• Use the Stair command (StairAdd) to create
  Straight, Multi-landing, U-shaped, 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.

3
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
