It is extremely different. You will know what things are possible, but it's hard at first to figure out how to do things. Naming of things does not match PC-DMIS or what you may consider industry standards, in some cases. I can't think of a specific example, but the Zeiss usage of a word you may think you understand, like 'offset' (just a made up example) will mean something completely different in Zeiss world. Lots of things are great in Calypso, but constructions and dimensioning in particular are much easier and user friendly in PC DMIS. Adding MMC to a hole in Zeiss practically demands a course in itself.
