Constraining the vector in Autofeature calculations

So far I have only seen that I can constrain the radius in feature calculations. Can we constrain result calculations to things like vector and position as well?

Right now we have a part with a free-form hourglass-like cavity on the inside. The drawing calls out that the circle formed by the smallest crosssection of this hourglass has a rather tight position tolerance. I figured I would just measure the hourglass like a cylinder and set the max inscribed fitting algorithm to obtain the smallest cross-section. Thing is, I would need to constrain the vector of this cylinder to exactly 1,0,0 IJK for the location to be correct.

Is this possible?

  • My thoughts are construct a plane at the x location of the cylinder point with smallest radial value then pierce it with the cylinder axis and apply the y,z position tol to the pierce point. Obtaining that x location from cylinder points would be the fun part, feels like an array could get it but not sure exactly how if it can

    The real gurus will probably have better answers monday morning im curious what they say
