So: OpenCascade contains both Cad & Cam capability right (let me know...). And, its sourcecode is pretty clunky or there is a VERY steep learning curve on its implementation...

If my above two suppostions are correct, then what we need (in my opinion) would be to integrate OpenCascade into a higher level program (probably similar to what Dan's post illustrated) that could simplify use of the sourcecode... I'm thinking something that lets one draw intuitivly (Think easy like SolidWorks) but translates back to what the source code needs. Second, it would allow for additional blocks of code to be input to do random things, like Wayne's suggestion (think "Add-Ins" in Excel). This way one could have a powerful solidmodeler with capability to perform a cam function after design is complete, output g-code to a machine, and allow for addition of opensourece modules like Spiro... A full, opensource solution for the entire gambut of Cad & Cam. Thoughts????
