object reference not set to instance of object

[Anonymous]

I'm using Inventor Fusion TP2 under Windows 7 64-bit.  After working with a model for some time, upon attempting to save I get the message "object reference not set to instance of object."  Once this happens, it will continue to happen indefinitely.  When I try to quit Fusion, it crashes.

Is there a workaround for this?  A fix?

Thanks,

-Rod

Hi Rod,

Thanks for using our product. As TP2 is a really old version, could you try the latest Inventor Fusion 2013, it's already on our labs here: http://labs.autodesk.com/technologies/fusion/downloadform.

And if you are interested in the Mac version, you can also access above link and get it on the right part of web page.

Please let me know if you still can reproduce this issue after upgrade.

Thanks,

Sally

I also get this message when I try to save after creating a pipe elbow using the sweep command.  I am using Autodesk Inventor Fusion 2013.

Any thoughts?
