  1. Chapter 9 Stairs and Railings

  2. 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

  4. Create Stair Construct

  5. Display of Stair in View Drawings

  11. Stair Shapes

  12. Turn Types

  13. Insert U-shaped Stair Flight start point or: (Select p1) Flight end point or: (Select p2) Flight start point or: Escape

  14. Setting Stair Dimensions • A-Width-specifies total width of the stair • B-Height-specify finish floor to finish floor distance • Justify-specify the handle to insert the stair • Calculation Rules button opens the Calculation Rules dialog box to control A-Stair Length, B-Riser Count, C-Riser, and D-Tread. • Calculation Rules can be set to Automatic or Manual

  15. Terminate with Options

  16. Top Offset

  17. Calculation Rules

  18. Flight Height • Minimum and maximum limits can be set for a stair flight. • Control of stair flight based upon: • Height of flight • Number of Risers • Landing is placed in stair when flight exceeds maximum flight

  19. Interference • Specify a headroom distance, walls and other AEC objects cut to provide headroom. • Left/Right Clearance value cuts AEC objects around the four sides of the stair

  20. Worksheets • Components and Landing Extension buttons opens the Stair Components and Landing Extensions dialog boxes • Dialog boxes are inactive if Allow Each Stair to Vary is toggled OFF in the Stair Style

  22. Worksheets-Landing Extensions

  23. Multi-landing Stair • Flight start point or: (Select point p1 as shown above.) • Flight end point or: ( Select point p2 as shown above.) • Flight start point or: (Select point p3 as shown above.) • Flight end point or: (Selectp4 as shown above.)

  24. Counter-clockwise Horizontal Oriented U-Shaped Stair

  25. Winder U-shaped Stair

  26. Placing a Spiral Stair • Select center of stair and start point to place spiral stair • Horizontal orientation- clockwise or counterclockwise • Arc Constraint-free, total degrees, or degrees per tread • Arc angle-total angle of stair sweep

  27. Grips of the Straight Stair

  28. Edit Edges Grips • Flight taper grip • Flight width • Vertex • Edge • Landing Width

  29. Grips of Multi-landingEdit Edges toggled Off • Lengthen Flight • Flight Start • Move Flight • Turn Point • Lengthen Stair • Move Multi-landing

  30. Customizing Edge of Stair • Use StairOffset to Offset edge of stair a specified distance • Project edge of stair to a wall or polyline, shown at left • Remove Customization of an edge • Generate a polyline from the edge
