Yeah, mostly because this is our pilot EFL project! It's really incredible what these libraries can do and how easy it is to build a development process around graphic design, UI scripting, and application programming. I just discovered the part option "precise_is_inside". This may serve my selfish purposes very well. In my free time, I'll have a look at ways of specifying a POLY in an EDC and post a proposal to the list. BTW, what happened to the API docs?
