Hello Mika,
You should check with Silma that the versions of I-DEAS, CimStation and the associated interface, are fully compatible. Certain combinations, with respect to version, of all three components, may be unsuitable for your purpose. I unfortunately don't have any experience with your precise configuration, but give us a call and we can discuss it further.

Best regards,
Andrew.
