How to modify the Side Contour of a Wall

by GRAPHISOFT and lnagy · updated: 03.21.2011

Walls in ArchiCAD by default have a uniform height along the whole element. By trimming Walls with Roofs or using Solid Element Operations (SEOs) with the Wall as target and Roofs/Beams/Slabs etc. as Operators, the contours of Walls can again be modified as desired. Here is another method, which uses SEOs and will create the desired Wall side contour in one step.

  • 1.Select the Wall the side contour of which you wish to modify. Go to an Elevation View (the line of the Elevation View should be parallel to the Wall.

  • 2. In the Elevation View, use a Fill to draw the desired shape of the Wall side contour. When you are finished, select the Fill and copy it to the Clipboard.

  • 3. Use the Design\Complex Profiles\Profile Manager to go to the Profile Manager. Click the New button to create a new profile and paste the Fill in the Profile Editor Drawing Window when it opens. For simplicity, paste it and move it so its lower left corner is at the Local Origin.

  • 4. Make sure the Wall option is set in the Use with field as we want to place a Wall that uses this Profile. Then click the Store Profile button to save it under a new name.

  • 5. Provide a name for the Profile (e.g. “Wall Side Contour-01”) and click OK to save it. Then close the Profile Manager Palette.

  • 6. Delete the Fill in the Elevation View as we will not need it anymore. In case you want to modify the side contour we will have the Fill in the Profile Manager.
  • 7. Return to the Floor Plan. Activate the Wall Tool. Switch to “Complex” Wall Complexity and select this new profile (“Wall Side Contour-01”) for its profile.

  • 8. Create a new Layer in the Layer Settings Dialog. Name this Layer “_SEO”. Set it to “Wireframe” and change its Layer Intersection Group Number to “2”. Then click OK to accept changes.

Note: We want to preserve this Wall we use for the SEO, but on a separate layer we can hide. With the “_” character at the beginning we make sure it is at the beginning of our Layer List. By making it a WireFrame layer we make sure it is non-intrusive in 3D and we will see the result of our SEOs while we still have the operators displayed for reference. By settings its Layer Intersection Group Number to “2” we make sure it does not accidentally intersects the Wall it is supposed to cut, giving unintended results.

  • 9. In the Floor Plan draw a short Wall (which is as wide as our Wall) perpendicular to our first Wall. Make sure the new Wall is on the SEO layer.

You may have to send this new Wall to the Back in Display Order so the original Wall is visible.

  • 10. Go to 3D to see both Walls.

  • 11. Bring up the Solid Element Operations Palette. Select the original Wall and make it the Target. Then deselect it, select the Profiled Wall and make it the Operator. Then select Intersection for operation and click Execute.
