All,
We have had several reports of instabilities in the drawing environment in Inventor R2012 resulting in unexpected crashes, or incorrect views. The most common workflows we have seen so far are crashes related to selection, select-other, undo. In addition hotfix addresses several other issues in the drawing environment.
We recommend that users apply the following hotfix so that these instabilities can be avoided.
Please note that this would need to be applied on top of R2012 SP1. If you don't have R2012 SP1 installed, please install R2012 SP1 prior to installing the hotfix. The readme describes the issues fixed as well as installation instructions.
The hotfix can be found at:
