Notio,
I am not sure what you mean by " building a new wall type every time ". I think that a composite wall is the best way to do a ICF wall type but once you have set it up once you should not have to do it again. You can make it part of a template file you use to start a new project or if you don't want to do that just past a piece of the wall from one project into the new one. It will add the composite wall type automatically. If I am misunderstanding please clarify.
Cheers,
Gerald Hoffman
