I am attempting to use the EXPORTLAYOUT command to export my layout to model space. This is something I do on a daily basis with no issues, but today I have a drawing that is giving me the error ** EXPORTLAYOUT failed to generate a new drawing. ** when attempting to export. I have received this error in the past and have been able to fix it by binding/detaching all xrefs, exploding cogo points and blocks, etc. but with this drawing file nothing I have tried has worked. Any ideas? I'm using Civil 3D 2017.
