Hi Speedy
I'm new to this, but as the name suggests I am a reseller. This is something we come across every day as you can imagine, until the CAD vendors decide to play nice and share relevant information the IGES, or STEP is the best way forward for now. There are some translators out there, but they are generally very expensive, and unless you are communication 100's of parts not really worth investing in.
I would be interested to know if anyone knows of any other reccomendations or short cuts though, just for personal interest.
Cheers, and good luck
