I do not see a problem to describe the work envelope with an equation with 3 (or whatever the number of axes involved) variables (there would be 2 variables for cylinder, 3 for sphere, some might get fancy and include angular axes as well), just like there are equations in kinematics modules. I just have no idea, what does it take to implement that, so that at the moment of loading the g-code file it would be checked against those equations.
