Need help on window placement on curved walls

Hi everyone! I need help on how to make the window be at the same angle placement as the associated wall. Thank you.

In the Profile Manager for the curved wall, show and edit the Opening Reference lines, they can be curved.

You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.

Windows cant follow pitch-angles. They are not scripted for this.

Overhead-roof-windows instead can do this, but there are very limited models and they can only be inserted in roofs and shells in archicad - not in walls.

A normal window would not function propper in the real world if inserted in a slanted wall, opening-mechanism's, the insulation and the airflow is'nt designed for such angles.

When You want such windows really for special-design purposes, the better way would be, to dig deeper in windows-design with some contacts to the window-industry-people and construct them by Your own -invent them by yourself from scratch.

In Archicad - just use a simple opening (without any window-frame-GDL-Library-part-script) and build the frames, the glass and other parts simply with Morphs or other normal Archicad-tools - just for displaying the design.

For the real-world - the manufactorers should bring their own technical drawings for their products to the building-side-workers.

As David mentioned, you need to adjust the wall opening reference line to match the curve of your wall.

It still won't really work, because your window is associated at the sill or the head.

You could resort to the old trick of placing an opening in the wall.

Place a small wall in the opening and incline it to match the slope of the opening.

Then place the window in the small wall, the window will hide the wall if it is larger than the wall.

Because you have a round window, make the wall as narrow as you can.

Barry.

Not a clear way, but some ideas, how someone could solve this problem..

Hi David, thank you for pointing me toward the Profile Manager’s Opening Reference lines. I didn’t realize they could be curved. I’ll explore that option and see how it behaves with my design. And yes, I’ll make sure to update my forum profile with my ArchiCAD version and OS for more accurate assistance in the future.

Hi Hmooslechner, I appreciate your detailed explanation about why standard windows can’t follow pitch angles and the real-world considerations behind it. The overhead roof window suggestion makes sense, and I’ll look into modeling it with Morphs for presentation purposes. Thanks!

Hi Barry, Thanks for elaborating on David’s point about adjusting the wall opening reference line. I see now why it may still be tricky due to sill or head association. Your “small wall in the opening” workaround is clever especially for a round window and I’ll give that method a try to see how cleanly it works in my model. Thank you!

Thanks again for following up with more potential approaches. It’s good to have multiple paths to explore, even if there’s no perfect one-click solution in this case. I’ll keep experimenting based on the ideas you and the others have shared. Thanks, again! Much appreciated.
