Environment Information
At Rill Architects we run ArchiCAD on macOS. If you work at Rill, this is your stuff. If you don't, but you work in ArchiCAD, you may find something interesting. Anybody else, I don't know.

This object is a tool for removing slope distortion from angled details such as rakes. A big improvement over this.

  1. Create the 2D detail in a section through the rake as usual.
  2. Open the Squeezer object and Save As into the embedded library with a different name.
  3. Within the object, open the 2D symbol.
  4. In the detail window, copy all the detail geometry and paste it into the 2D symbol.
  5. Save the Squeezer object and place an instance in the detail window.
  6. In the settings of the object, set the slope of the roof.
  7. The object now shows the geometry as if the detail had been cut perpendicular to the slope.
  8. Explode the object to convert it to normal 2D elements.

Squeezed rake

You can keep reusing the single embedded object for multiple details; once you have the new 2D geometry placed, you don't need the object symbol.


•The Building Material nature of the fills is lost.

•The grouping of 2D elements by parent 3D element is lost. The whole detail becomes one group.

How it works:

In the 2D script there is a MUL2 command which keeps the X direction the same, while squeezing the Y direction by a factor of the cosine of the given slope angle.

Then there is a FRAGMENT2 command which simply places the content of the 2D symbol, with the squeeze applied.
