Hi Dean,
Thank you very much for your quick respons.
We are using AutoCAD 2015 in our company together with Inventor, DesignReview and DWG Trueview.
I have seen that DesignReview (latest version is 2013) can normally only work together with a matching version of DWG Trueview.
Luckily I found a trick from AutoDesk to do something in the registry to overcome this problem.
But then raise the question what is really the difference between the different versions of DWG Trueview?
It is not possible to find that somewhere on the website's of AutoDesk.
Maybe newer versions have extra options? Do you know?
Thanks a lot,
TiegDani
