Does the Workbench 11.0SP1 plugin provide support for Autodesk Inventor 2009 x64?
On 32-bit Windows, Inventor 2009 is not officially tested, but appears to work with 11.0SP1 with the same plugin as 2008.
On 64-bit Windows, Inventor 2009 is now 64-bit native. This means the hybrid plug-in (supplied with 11.0SP1 x64) that
connected 32-bit CAD to 64-bit ANSYS Workbench will no longer function.
Prior to Inventor 2009, Inventor was a 32-bit native application that was capable of being installed on Windows x64; moreover, prior to 2009, all Inventor was 32 bit.
A Special Version request to add Inventor 2009 64-bit support to 11.0 SP1 is available on the Ansys Customer Portal
