Wilbert, For a basic core metrology package on a Zeiss machine, I ask everyone can you really get more user friendly than Usoft? The answer is no. However, I have seen the Calypso demo which is somewhat complex to put it mildly. No offense to Zeiss intended but I'm sold on their competition "CheckMate". In my opinion, there is no finer CMM than a Zeiss. All Zeiss products are world class industry leaders. This is what they do best. Origin makes the finest CAD/CMM software and that is what they do best since 1988. In combining the two here at Lapeer Metal Stamping our achievements include ISO-9002, QS-9000, Ford Q-1, Chrysler Gold Pentastar, Mazda plant Mgr. award and GM Supplier of the year for 1998. We are very proud to be recognized as a World Class Supplier in this a highly competitive global marketplace. Regards, Geoff Sr. CMM Programmer Lapeer Metal Stamping LMS Metrology Lab Lapeer, MI
