yep that's autotake for you, they just make it difficult for everyone.

Rhino Import Translator Add-in for Inventor Coming Soon http://labs.autodesk.com/utilities/rhino_import/ I guess same will happen with Revit etc.

So hopefully MoI will benefit too (?)

also that may help.

>>>There is a library that may be possible for me to license in the future to help with reading and writing to DWG, but it is fairly expensive. And even with the library I expect for it to be quite a lot of work to tackle the problem, so I'm not sure when that may happen even with the library to assist.

Hi Michael Is the library you talk about the RealDWG ? http://usa.autodesk.com/adsk/servlet/item?siteID=123112&id=9078672
I have bad experience with apps like SolidWorks that uses the OpenDWG, it is not a solution IMO.
Also there may be a good work around.the .DGN file format and The Bentley/Autodesk Agreement

So what I am thinking is since Autocad, Revit etc. reads and writes .DGN It may be a solution if MoI was to support just the DGN file format.
