My gable wall won't attach to the top of the roof

[Anonymous]

Hi, I can't attach my gable wall to the top of the roof. The base constraint only goes up to second floor, there is no roof line option. 

Note: I am new to Revit.

Hi! Select wall - press Attach Top/Base - select roof.

Hi,

Sorry I forgot to say that doing that is doing absolutely nothing, so I am out of ideas.

Can you attach the .rvt?

[Anonymous]

In the screenshots it looks like the wall is currently attached to a hipped roof (in a previous phase?)

If this is the case, you will need to put a new wall on top of the existing one and attach that to the new roof.

Sorry does that mean you want me to attach the whole file?

I'm new to this ha

Hi Alex yes this sounds correct.

How do I put a new wall on top of the existing? Because when I do, it doesn't actually become a gable wall it just becomes a big square wall protruding from the roof.

Yes, rvt project file. Just make a copy, then Manage/Purge unused, save and upload.

Try dragging the base of the new wall slightly lower until it will let you attach it to the roof

Ok hopefully this works?

[Anonymous]

It does this if I try to create a new wall

Is this correct?

[Anonymous]

YES!

How did you do it?

I disallowed join on both ends of the new wall, aligned it to the front and rear walls, attached it to the roof, and joined it to the wall below (making sure to switch the join order to keep the existing wall untouched)
