Hi there,

I'm trying to draw this orifice using gambit (as attached image), and so far I couldnt figure out a way to draw it. Basically the "black rectangular shapes" are perforations on a single plate. I know the size of each of the perforations but just dunno how i should arrange them in such an arrangement.

Does anyone have any suggestions? Thanks.

Hello,

you have 3 concentrical "rows", take for example the internal circle, draw manually one of the shape and copy and rotate this 10 times (or the number of holes for this circle). Probably you have equal spaces between the holes, so you can use some constant angle increment like 360/10=36 degree for the internal circle.

Same for the other 2.
