Issue with "Historic Reveal" display in Archicad 28 & 29 Floor Plan

arch_08 — Thu, 26 Feb 2026 17:57:46 GMT

I’ve noticed that windows in Archicad 29 are having issues displaying the "Historic Reveal" correctly in the Floor Plan view. Actually, this seems to apply to all reveal types that should be angled (splayed).

Attached is an image of the window in 3D view.

And here is an image of the same window in Floor Plan. As you can see, the reveal appears straight instead of angled.

I have noticed that Archicad 28 suffers from the exact same issue.

However, Archicad 27 displays the window in the floor plan perfectly—exactly as it should be.

It is the same window object, with the same settings, in the same wall, yet everything works correctly there.

Is anyone else experiencing this issue?

Thanks and best regards

Operating system used: Windows 11 25H2

Hi @arch_08

Check the Model View Options you have applied to your view. In AC29 you have more control over the visibility of each window/door part individually.

Thank you very much for your help.

I adjusted the reveal settings in Model View Options, but I overlooked the fact that they are set separately for windows and doors. I only had it enabled for doors.

Thanks again! 🙏
