Probar 2D is a powerful AutoCAD add-on designed for Structural Engineers and Drafters, to create reinforced concrete detailed drawings. It enhances productivity, ensures compliance with local standards and smoothly integrates with other Prokon Software Modules.

Step-by-Step Guide to Detailing Staircase

• Setting a new Project in AutoCAD
  • Launch AutoCAD
  • Open an empty drawing
  • Ensure you are working in Model space
  • Annotation Scale should be 1:1 for the model space.

• Creating a Staircase layout
  • Import a PDF Drawing (in this case)
    • Drag the staircase PDF drawing into AutoCAD. AutoCAD will prompt you to enter the page number to import (enter “1” if only one page exists).
    • Specify:
      • Insertion Point.
      • Scale Factor: Use 1 (can be rescaled later).
      • Rotation: Enter 0°.

• Enable Snapping for Tracing
  • Select the PDF.
  • In the Properties panel:
    • Enable “Show Underlay” to view the imported PDF.
    • Enable “Enable Snapping” to trace over the staircase edges.

•  Rescale the PDF to Match Actual Dimensions

• Use SC (scale) command
• Select the base point
• Specify scale factor or use reference, in this case reference
• Specify the reference length on screen
• Enter the actual length 4785, the drawing will be scaled.
• Adjust dimension styles to a suitable drawing scale (e.g., 1:25).

• Drawing over the staircase layout
  • go to the home tab
  • use drawing tools (e.g. rectangle) to trace over the stair profile.
  • Copy the traced staircases to an empty space for clear annotation.

• Add Staircase Annotation
  • Includes the following labels before launching the wizards:
    • Riser
    • Tread/going
    • Landing width
    • Staircase width
    • Staircases gap between the two flights

• Launch the Staircase Wizard
  • Navigate to: Probar 2D Tab > Wizard drop-down > Staircase Wizard 

• Input Staircase Geometry
  • In the wizard interface:
    • Select Double Staircases.
    • Enter Staircases Dimensions as measured on the drawing:
      • Tread/Going: 300mm
      • Top Level of the Staircase: 2720mm
      • Landing level: (170×8=1360mm)
      • Width of the staircases: 1350mm
    • Define Landing Dimension:
      • Size and Position of landing
    • Input Rebar Dimensions:
      • Main Reinforcement: Bar diameter and Spacing
      • Secondary Reinforcement: Bar diameter and spacing
    • General Settings: Define Support Conditions ( top and Bottom)
    • Link Section and Plan bars

• Configure Reinforcement Layout
  • The wizard automatically calculates the reinforcement requirements based on input geometry and design parameters.

• Preview the Reinforcement Layout
  • Review the automatically generated rebar layout:
    • Main bars in the steps and flight.
    • Distribution bars in the landing (if any).
  • Adjust the schedule to ensure clarity and accuracy

• Generate Bending Schedule
• The wizard generates a complete bending schedule, including:
  • Bar shapes.
  • Lengths and diameters.
  • Quantities.
• Adjust the schedule to ensure clarity and accuracy.

Summary

Probar 2D’s Staircase Wizard simplifies a typically tedious detailing task. From drawing tracing to bar scheduling, it reduces manual errors, speeds up delivery, and ensures compliance with detailing codes, SANS 282:2011 and SANS 282:2004.
