Missing toggle for wall surface override

[Anonymous]

Hi,

in a project in AC22 (v3009 for Win) I cannot toggle the wall surface overriding. In a new project it works fine but in my current project I cannot switch it off on any walls.

I've got another project from the same guy, who made both buildings' surveys. I think, he made them in an earlier version of AC. Is it possibly the reason for my problem? And if yes, how can I solve the issue?

Thanks,
Áron

The file was likely created in a version before AC17 - when we introduced Building Materials.
To maintain compatibility, we have what we call "legacy mode" to avoid any changes in the model/appearance when migrating files.
To turn off this "legacy mode", go to Project Preference / Legacy, and turn off "Use legacy interaction and Surface methods for model elements".
