Perpendicularity - datum/feature evaluation.


---
 Share

Recommended Posts

My datum is a horizontal 3d line about 1" long. Feature(s) being evaluated for perpendicularity are 7 planes
that surround the datum radially (like a star). What is the proper evaluation for both datum and feature?

The cookbook does not give a plane as an example of the evaluated feature. I think it would be OT for the
planes, and MF for the line? Can someone confirm this?

Thanks in advance.

OT - Yes

but:

constraining the vector of the plane parallel to the datum. (2x)

The distance of the two constrained planes (parallelism=0)
is the perpendicularity.

Thank you Andreas. I'm not sure I know what you mean by;

"constraining the vector of the plane parallel to the datum. (2x),
The distance of the two constrained planes (parallelism=0)
is the perpendicularity."

The 7 planes are all 90 deg to the datum (a 3D line)

Just drop in multiple "Angularity" characteristics and select that central axis / 3D line as your datum. Then in the "comment" section of the characteristic, say something like "Perpendicularity as Angularity". Sure, it's a substitute, but it should also tell them what they want to know.
