characteristic area of passage - displacement by cad

[adac]

Hello, everyone!
are a new user, study ing. mechanics and are at first arms with
the programs cad. in particular use solidworks 2010.

I hope not to wrong section to put this question: I would like to know how it is possible to measure an area of passage, depending on the shift of the element that determines that area, using a cad program (better if solidworks). I better explain: for example, in an oleodynamic distributor when switching the drawer, a passing light appears. I would like to know the trend of such light when changing the drawer (graphic x= shift, y=area) using the three-dimensional model cad, without having to resort to an analytical evaluation with matlab programs.

Does anyone have any ideas?? ? ?

thanks and greetings!

you can connect a excel sheet that makes calculations to model 3d. or you can create a sketch on the model or a solid for the passage volume and sample a series of known openings with the automatic value of the sketch area. si tabula e si get the curve "station drawer" vs "pass area"
