as autocad calculus the properties of regions

[ing_82]

good morning, someone would know where to find indications about how autocad calculates the properties of regions whose perimeter is not a simple broken line, but also composed of portions of arc, spline. etc.
Thank you.

Hi.

Thank you. In fact my question is partly wrong, in the sense that it is not as much as autocad does, but as you could/can make a computer do something like that, that would be my problem.
However, wishing to keep autocad results as "exact" in the case of this kind of figure, I would like to know how it does so that I know which is its degree of accuracy of results or if some "hidden" variable of the program affects how autocad calculates these values.

Thanks again
