Caliper vs X/Y/Z distance

[[Ca...]]

There is a .004'' discrepancy from caliper x distance vs just x callout. Caliper is using base alignment from plane(plane is use for planer rotation and zero on x) to hole x distance callout. I'm assuming just x call out of hole is also using base alignment so why the discrepancy?

Check the caliper distance evaluation. It could be set to Maximum or Minimum.

I have and they are evaluated at center. I found the .004'' difference.

X callout is center of base alignment to hole whereas caliper distance is center of plane B to hole.

 Sorry, but you have a mistake there.

If you want to have same result you have to use that Base-Plane -B- as rotation in space or at least as planar rotation and as X origin.

Value on X,Y,Z is from origin of feature - for plane it's one of corner.
Using caliper distance and "Center" is from center of feature, so if that -B- plane is not perpendicular to plane -A- and -C- then there will be always something.

I almost wish they would just disable the output or make some warning (like the annoying one when you switch to a UPR pre-filter) when trying to tolerance an axis (X, Y, Z) from a 3d feature.

I know I'm showing my age but I seem to recall there was an option in the plane window to select the mid-point of the plane.

Out of curiosity I've opened a plane feature, but I don't see such an option.

Tom, you don't look a day over 30. I'll be 63 in August. I'm probably the oldest dude in the forum.

Thanks...LOL Oldest?  not even close dude.   I was referring to versions of Calypso in use around 15 to 20 years ago

Wonder why it was removed?

Nah, I'm 66 and retiring very soon. Anybody older than that?

I'm 62, but when I wake up and try to get out of bed, I feel 102.

Either you recall "Plane" to a "Point" feature or edit a "Plane" element in Characteristics tab where you can select which point of a plane will be evaluated.

I will just add, that result may vary, because of measured points. So it's the same as using point with recall measured points.

Good job Mateusz....  I never noticed that before.  Does anyone remember this option being located in the feature, i.e. back in the 2000's?  Or, is my brain starting to fade?...lol
