One thing I like with SketchUp is that at the base level it’s a general 3D modeler that you can make just about anything with. With plugins, you can make a lot of whole assemblies very fast. With a package like Chief Architect, if you don’t like the way it does something, your choice is to look at a completely different package like REVIT or Vectorworks. With SketchUp, if a plugin isn’t to your liking, there are other plugins, and if you’re ever stuck with a situation your plugin doesn’t handle, you can always get down with native tools and push through anyway. I’ve been using Medeek plugins for a while. They handle the most common framing situations, but I almost always have a situation that’s out of it’s bounds. It still works by doing the obvious stuff first quickly, and then I go in and tinker with it with native tools.
I put an example in this post.
