help me measure it, how would u dimension it

pcdmisstudent
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

  • Well, if they are conical, measure the big boy hole as cone - or as two circles and create a line between the circles and use that as leveling and origin.

    Normally, when things are conical, the diameter you are looking for is usually set to a gage dimension, either a height/depth on the cone.
    Your snippet does not tell us if that is the case. We don't know if you do have a check distance where the "diameter" should be 6.86.
    Is the 6.86 dimension valid for the entire length or just at a set height?

    The tolerance 0.1 might be so large that it encompasses the length of the cone AND a 2° draft angle (the variation that the 2° draft angle causes is covered by the tolerance).
