Free Yourself from Parametric Programming

"It is a well known fact that CAD software vendors use their proprietary file formats to lock users into using their software. Parametric solid modeling systems make it impossible for their solid models to be worked upon in another parametric system without losing parametric information. They cannot even save to an earlier version of their own software. Users wanting to achieve interoperability between two parametric modeling systems can do so only using neutral file formats suh as IGES, STEP, SAT, etc. wherein the solid models come in as dumb solids, making it impossible to edit the parametric features of such models. And this is a big problem. A problem which CAD vendors seem to agree is best left unresolved."

"A CAD 2.0 system user is free from the headaches that come with conventional parametric modeling systems and can spend his time doing what he should be doing $B!>(B designing, not doing book$B!>(Bkeeping of parameters, relationships and constraints in a feature tree or wondering whether another user will be able to modify or even view his mode in another software, or even in an earlier version of the same software that he is using."

"Moreover, proprietary file formats no longer tie down the user of a CAD 2.0 system. He is free to move to any other CAD 2.0 system at any time and he will be able to directly work with his models right from day one. He is not forced to use the same software as others he is collaborating with, and neither does he need to bother what software others are using."
