How to trim a wall to a stair?

Description

In this project, there’s a storage space under the stairs, which needs to be fully enclosed by walls. The challenge is trimming the walls to match the shape of the stairs. How can this be done?

Solution

To achieve this, the Solid Element Operations tool in Archicad can be used. 

1. Switch to 3D view for clear visibility of your model.
2. Go to Design > Solid Element Operations on the menu bar to open the tool window.
3. Select the walls to be trimmed and click Add as Target in the Solid Element Operations window.
4. Select the stairs to be used as the trimming element and click Add as Operator.

5. In the Operation section, choose Subtraction with upward extrusion from the dropdown menu.

   

6. Press Execute to trim the walls according to the stair shape.
7. Confirm that the enclosed storage area’s walls now fit perfectly under the stairs.

By using this method, you can ensure that the storage area under the stairs is properly enclosed, with the walls seamlessly adjusted to the stair’s structure.
