Key Technological Concepts and Features Covered

Stair Layout and Dimensions

• Setting stair height relative to a beam and ground level.
• Calculating rise and run based on standard American building codes (maximum rise approximately 7 inches).
• Using division and adjustment to find the correct number of steps (e.g., 16, 17, 18 steps).
• Defining tread going (11–12 inches) and adjusting step dimensions interactively.

Drawing and Modeling Stairs

• Using lines and arrays to create treads and stringers.
• Inserting a concrete slab to visualize stair placement.
• Adjusting stair start and end points, avoiding common mistakes such as picking the first tread as the start.

Advance Steel Stair Macros

• Using the stair macro for automatic stair creation.
• Modifying stair properties such as landing profiles, stringer sizes, and nosing.
• Customizing profiles for stringers and landings (e.g., changing channel sizes).
• Managing weld types (shop weld vs. site weld) and bolt connections.
• Adjusting step types (e.g., bent pans with carriers) and weld details.

Angle and Geometry Checks

• Verifying stair angle using measurement tools and manual line drawing.
• Calculating the exact stair angle (example given: 8.5 degrees).
• Adjusting bending angles for step pans and nosing to match calculated angles.
• Ensuring no clashes occur between stairs and structural elements.

Connection Details

• Adding stair anchors and miscellaneous connections like angle brackets.
• Adjusting cutbacks and plate thicknesses to avoid clashes.
• Setting anchor reference points aligned with stair fronts.
• Using UCS (User Coordinate System) settings for precise feature placement.
• Copying connections and verifying identical parts using the output difference tool.

Practical Tips and Workflow Advice

• Importance of checking and adjusting dimensions iteratively.
• Using 2D wireframe mode for moving and aligning stairs.
• Avoiding overcomplication by manually adding plates or connections outside macros.
• Saving stair configurations as templates for reuse (e.g., saving as “ASBEG Concrete”).
• Recognizing when to eyeball certain dimensions like tread bending due to manufacturing tolerances.
