Hello there fellow solidworksers (as a welcome change to all the discussions about UI in 2016) I have an issue I would like help with.

I am trying to import a DWG, something I do usually without too many issues. I can view the file in Autodesk trueview but when I try and import the file I have various issues flagged and an empty sketch on opening? Anyone have any ideas? I would be most greatful. This is a plan view, the space between the angled units should be approx 25mm if that helps, usually I would expect it to open at 1:1 but you never know.
