Hello Adam,
CAD data can be exported to your Zeiss CMM software to reduce program time and gain many other benefits, the first being the ability to re-use your valuable CAD data for inspection. The SDRC Ideas / Zeiss CMM combination is fully supported by Silma's CimStation Inspection, most notably in use at Ford Motor Co. I represent Silma in the UK, and would recommend that you take a look at Silma's site - http://www.silma.com or contact me at - andrew@acel.demon.co.uk if you wish.
Andrew.
