Attic Vent and windows disappear

[Paul in Ottawa]

Interesting, in CA 10 I found that my attic gable walls would loose the material change I put on them on occasion. I wonder if this is related?? I have not done enough in X1 to know if it still happens.

Is the vent/window placed in an automatically generated attic wall or a manually drawn or edited one? I think that's the only time I have had them disappear, when they were located in an edited or manually drawn attic wall. It was due, I think, to the walls/floor/ceilings rebuilding when you regenerate the view. The Auto Rebuild can be unchecked, and you can check Retain Attic Wall. Hope that helps.

I am placing the window into an automatically drawn attic wall. Make sense to me now why this is happening.

Thanks

Bryce I can not find the "do not rebuild walls" radio button. Do you know where it is.
