Walls not attaching to roof created by selecting faces of mass

[emorgan]

I have created a roof by selecting the faces of a conceptual mass, and now I'm trying to attach the tops of walls to it and it will not attach any walls to it.  I get the error messages "Can't keep elements joined" and "Can't keep wall and roof joined."  I'm trying to attach straight and curved walls to this roof, so editing the profile of each wall is not feasible.  I'm also trying to connect generic walls as well as curtain walls to the roof.  The walls are completely covered by the roof, FYI.

A couple of screenshots perhaps?

Can you share your model?

Attached are a few screen shots.  Hopefully they help.

Not sure what's going on.  Maybe you do need to share the model, or at least the mass, the roof and a couple of walls.

See attached.  I boiled the model down to a floor, the roof, a few walls, and the massing plane I used to create the roof.

You need fix the SketchUp model a get rid of the triangulated panels.  They are too complicated for clean attachments from the walls to the roof.

Here is what I would do. Create a new roof. When you are sketching for the footprint of the roof, Pick Lines from the original roof to get the sketch. When you get he roof associate it with whichever level you need to. Then select the roof, go into Modify Sub Elements. That will allow you to select individual points and set their height to match the original roof.

At the end of this I would like to say (again) that Revit is so much happier with content that it creates!

Here are the Roofs created from a cleaned up mass.  Walls and curtain walls attach to them perfectly fine.

Thanks for spelling that out for me!  I could not figure out on my own how to do that weird roof form without taking it out of Revit, which I did not want to do.  It is working for me now!
