hi, i have acquired a second hand brown and sharpe (non CNC) with pd-dmis, i am just getting to grips with it and have had no training so am a little stuck. i'm trying to get the profile of an odd gear so that i can export the dxf and wire erode the new gear straight from that. when constructing the curve i'm doing it one point at a time and then creating a curve from those individual points, however i am getting some strange results in the way of points that dont lie where i'd expect them to, resulting in strange curves as opposed to the normal involute form i was expecting. i dont think its my bad hitting as i've tried doing it a few times but it could be! any tips would be appreciated!!

also, stupid question but how do you simply find the diameter of a circle?!?! i can define and construct the circle but under 'dimension' there's no diameter function? what have i missed?

thanks in advance, any help would be appreciated!
