@Kevin K Hey hey
Unfortunately I can't post this file for help - active NDA. *.mvr is the file format that exports into Vision, this is the new thing VW/Vision are moving into.
As for the meshes, they are a custom truss that import in as meshes, trying to simplifying them only causes the objects to disappear. I'd like to convert them to a polygon or something simpler to work with. Currently the dwg conversion is running my vwx at 350+Mb, so not great for any work.
Dwg files converted seem to be so bad that running purge command runs up my RAM and eventually crashes.
I'd like to get this to be a much simpler file (<20Mb), add my fixtures and information, and export it into Vision.
