What Graphical Only 3D Format Do You Use?

Hello,

I need to share a 3D model with a third party, but do not want to send the full details of assembly/part files.

I would like to save my parent assembly to a read-only, graphical data only type of 3D format.

What format do you suggest?

I tried WRL so far but it was creating a HUGE file, so I ended the process before it completed. I also tried HCG, and although SW seemed to be able to export to HCG, I couldn't then import it back into SW. I believe CRG files are for Catia only.

Thanks for your help.
