not able to open any file extension expect *.sldxxx.
I have tried *.3dxml and *.CATPart.
Error messages says "Error reading file"
What troubleshooting can I do? I have tried my IT dept but they have taken 2 days so far and no solution.
Appreciate any help
It's not a viewer for all types or at least it isn't in my SW2015 version.
