I would like to add curved stairs or add a spiral staircase to my plan. How can I do this?

Curved staircase in entryway


There are several ways to create curved or spiral stairs in Chief Architect. One way is to place a spiral staircase from the Library Browser while other methods require the use of the Stair Tools.

To use the curved stair tools

  1. Select Build> Stairs> Curve to Left  or Curve to Right  from the menu, then click once in a floor plan view to add curved stairs at that location.
  2. To move, resize or rotate the stairs, click the Select Objects  button, select the stairs, and use the edit handles that display to adjust the stair to your liking.

Note: Stairs created using any of the Stair Tools can be curved or straightened by selecting the stairs, holding down the Alt key, and then dragging either the top or bottom edit handle to either side.

To curve a straight staircase

  1. Select Build> Stairs> Straight Stairs  from the menu, then click and drag to draw a run of straight stairs.

  2. Click the Select Objects  button, then click on the staircase to select it.

  3. Click on either the bottom or top edge edit handle, hold down the Alt key on your keyboard, and drag the edge in any direction to curve the stairs accordingly.

    • Instead of holding down the Alt key, you can instead click and drag using the right mouse button.

      Note: The Alt key and right mouse buttons are shortcuts for the Alternate edit behavior. If you would like to enable this edit behavior for the left mouse button, select from the menu: Edit> Edit Behaviors> Alternate.

To place a spiral staircase

  1. Open the Chief Architect plan in which you would like to place a spiral staircase, or select File> New Plan  from the menu.

  2. Select View> Library Browser  from the menu to open the Library Browser window.

  3. Browse to Chief Architect Core Catalogs> Architectural> Staircases> Spiral and click on one of the spiral staircases to select it.

  4. When you move your cursor into the drawing area, it will display the Fixtures (Interior)  icon.  Click once to place the selected spiral staircase at that location.

  5. Once created, you can use the edit handles to move, resize or rotate the staircase as needed.

You can also import spiral staircase symbols from third party sources, such as the 3D Warehouse. To learn more, see the Related Articles section below.
