help me measure it, how would u dimension it

hi all
i got a measuring/construction/engineer/noob problem.
i have this small 40 degree, 2 degree conical thing, that is supposed to have a diameter 6.86mm where it is as smallest, and its supposed to be centered in the casted hole(D), and perpendicular to the plane(A)
i dont know how to measure it, since its a very small surface, and its also not cylindrical, its conical with a 2degree angle.
so i have to measure it as a cone. and then construct a circle using cone feature, but the results are very unsure.

the matching part has the exact same feature, except its internal, and it should run free over the tap thingy.
how can i measure it
or how would u else dimension it, so that the matching part fits.
ty all, thanks for ur feedback

  • how would i compensate for cosine error? (maybe this is question for
    So, if i understand this correctly
    Measure big boy cone, level and orgin to it
    measure two circles on the small arc using fastrad
    compensate for cosine (?)
    construct BF cone using the two circles
    dimension XY for this cone
    orgin to BF cone
    use vector points on small arc
    dimension PRAD

    thanks ninja



    What tip size are you using?
