Stair Tool Advanced – How to create a Ramp using the Stair Tool?

by Andrea Polgár-Veres · updated: 01.04.2018
 In ARCHICAD there is no dedicated tool for ramps but there are many ways to model one. You can use Objects, the Mesh even the Railing Tool is good for that purpose. In this article we will show how to model a ramp using the new Stair Tool from version 21.

Create a custom profile

Open the Profile Manager Palette and create a profile with the desired width and thickness of your ramp. Do not forget to check Objects under ‘Use with’.

Turn off Finishes in the Stair Default Settings

Activate the Stair and open its Settings. In the Finish page turn off Finishes (both Treads and Risers) all together.

Set Stringer for the Structure and use the custom Profile as Stringer.

Use the ‘Stringer Only’ option for both Flight Structure and Landing Structure. ‘Stringer Right’ is the only structure you will need. (The right side is used, because of the location of the Profile origin).

Select the custom Profile for the Stringer

Make sure that the ‘Stringer Profile Anchor’ is set correctly. In this example the Profile’s anchor point (= origin) at the top right corner, so the Stringer is line up with the Finish. If the anchor point is on a different place, the Stringer will be placed next to the Finish. In this case you can fine tune it with the ‘Stringer Profile Anchor’ setting under Stair Default Settings / Stringers – Flight / Stringer Component Settings.

Adjust support ending

Select the Stringers – Flight than adjust the support ending and connections dimensions as desired.

Set the desired slope and width

This can be done in the Structure settings. Before doing that  uncheck the minimum values under ‘Rules and Standards’. To get a ramp with 20% slope for a story height of 3 meters, the length of the ramp should be 15 m. Set the ‘Going Depth’ to ‘Fixed’ and enter 150 mm, then select 100 Ramp for the ‘Number of Risers’. Enter the required width of the Stair.

Adjust the Floor Plan Display

  • Under Floor Plan Symbol Components – uncheck Model View Option, and select: Walking Line, Up/Down Text, and Structure.
  • Adjust the Relevant and Above Relevant Symbol settings.

  • Under Floor Plan Display select Grid and change the Grid Display to only show the boundary for each Story settings than match line settings.

  • Under Floor Plan Display select Structure then select show stringer on Visible and Hidden Parts than match line settings.

  • Under Floor Plan Display / Walking Line – Match settings for Visible and Hidden Lines

Draw your ramp in floor plan view or 3D view.

In this case Stinger was used for the ‘body’ of the ramp, but Stair – Beam can be used for this purpose as well.
