Is there a way to delete a wall while saving the sweeps attached to the wall?

Hope someone can help, thanks.

I used sweeps for the whole facade and I get a ton of errors, maybe I should turn the sweeps into Mass instead.

I can't readily tell which parts are wall sweeps from you image but it appears curtain walls maybe a better approach.
