problem constructing a circle

[djone368]

because of the location of the hole
I cant measure an auto circle,so I have to go in take 2 points -pull out - do a tip change - go back in - take 3rd hit - pull out do another tip change take 4th hit

I construct the circle(best fit )

I dimensin the circle
I am looking for location in x and z

they seem fine but my y is uot hundreas of mm

the hole is a master locating pin on a body side that controls x and z

any replies appreciated
thank you

There is an option in Pcdmis SOMEWHERE to project 'learned' or 'measured' features into the current workplane. Is that on?

I am not sure

where would I find it ?

does it not just default to the work plane you are already in ?

Are all of your tips qualified? What does it look like for size and roundness when you report those? Any chance you could post some code?

I measures it in the workplane you are in, BUT, I remembered hearing about an option SOMEWHERE in one of the many set-up screen that would then project your measured features INTO the plane (which tou be at ZERO for that axis) and that sounded like it might have been what was going on from your post. It is in the F5 setup menu, you are looking for "MOVE FEATURE TO REFERENCE PLANE". If it is marked, unmark it.

That is in Edit / Preferences / Setup.

Post the code

It was the work plane
