position of a Surface Point
position of a Surface Point
(OP)
Is it correct to call position of a Surface Point - |POS|x.x|A|B|...| ( measured with CMM)?
Point as such is not a feature of size, or is it?

All I wanted was few statements as Dingy2's, so I can prove that there are some other GDT than TP(mostely misused here around me).
I hope you all don't see me too annoying, thanks

Profile is a pretty flexible and powerful GDT tool. Get to know it better.
RE: position of a Surface Point
Problem is to represent use of a Profile to my engineers.
Yesterday I read old thread written by Sirius2; around me, main problem isn't being "Bossed" around by arogance. No. My problem is ignorance. We called educator for GDT twice within one year.Got together about 20 people.
Result is - any chair or table present on that class took more knowledge than most of involved persons.
So again: I need outside statement/opinion that Point is just a point and that's it. My folks wouldn't listen to me, but they do have pretty good ears for everything foreign.
So again, thank you all
RE: position of a Surface Point
I agree. A point is just a point.

Just like cylindrical features that have theoretical axes, slabs that have theoretical center planes, spheres have theoretical center "points" or centroids.

My thougths are, all GDT can be misused, such way as describing 3D world with only two dimensions. Stephen Hawking wrote some on the topic.
Is it logical to ask : what is the minimum number of points needed to describe Surface Profile? Is it one?
( We get T zone as output AND +/- deviations with respect to axes)
