At our studio we had a major problem in Archicad 27. When modelling in 3D, no geometry edits were shown in the 3d window.
New geometry not visible in 3d window, modifications in geometry was not showing, deleted geometry was still shown. The edits in geometry became visible when closing the 3D window and opening it again from plan view. Same for hiding and showing the layer. The reoccuring problem in Archicad 27 is shown in the video below.
Solution:
The solution is to pin and unpin some geometry to a Renovation Filter.

Hello @ESK,
It is probably not a bug 😉
You should to unlock 3D Cutting Planes.

ESK,
You should put your system configuration in your signatures, it would make it easier to help you.
There are similar issues for users on Intel-based Mac with AMD cards? Do you have that configuration?
In this thread, there is a workaround offered that might help:
AMD Ryzen9 5900X CPU, 64 GB RAM 3600 MHz, Nvidia GTX 1060 6GB, 500 GB NVMe SSD

Hi Christophe
Thanks for suggesting a solution. Disabling 3D cutting planes didn't make a difference in this case.

Hello ESK,
Are you able to share a mod file about your project ?

Hi Christophe
My own solution works fine, I just wanted to share the information in the forum. I'm not allowed to send a file containing our company standard template. Thanks for offering your help.
