Analysis view

[dmis100]

Just tried this again on a different model. Just a face and a dia. with 5 points measured in the z axis. Should show nominal line and 2 boundary lines but as shown in attachment the boundary lines are above and below in separate layers. Capture2.PNG

[mckenzie]

are you measuring a plane or a circle? the boundary lines look like its measuring the plane in the z axis

[dmis100]

That's just a 5 point circle.

[KIRBSTER269]

That's a circle? maybe your video card is bad. What is your PC specs, Jim?

Can you open your OpenGL? and let us take a looksy at your settings?

Well boundry lines are above and below because these are the 5 plane hits on the Z surface.. All you see here are the 5 hits on a plane and this is exactly how it should look. If you want to do a form on the diameter you need to dimension circularity and create an analysis on that.

[KIRBSTER269]

circle not a plane

[Peter Fuller]

I read that it was a diameter, but that's most certainly not an analysis of a circle.

[KIRBSTER269]

Yeah, That was my surprise, That's why I said what I said in Post #4. Something is definitely wrong.

[dmis100]

Capture3.PNG It.just a 5 point circle. Brand new setup only 3 weeks old. See attached.

[KIRBSTER269]

This one has got me baffled. I have tried everything to get mine to do this. definitely enough goods inside

[Mike Ruff]

Can you post the code for the relevant features?

[dmis100]

The points in this plot was measured in the yz plane but yet the tol. bands are in x. The plot used for circularity worked Peter. Should have knowed that been away from this for about a year. Just getting familiar again. I will go back and check the points I used to create it. Capture1.PNG

[dmis100]

This is just a section of the code. The data was created from a series of circles then the points was extracted from them. This was measured in the yz plane.

All of your vectors are in X.

[RandomJerk]

I noted a couple of things. One, don't think you need this:

CIR25.HIT[1..1]

CIR25.HIT[1]

will work.

But the issue is the THEO and ACTL for the cast points - they all have the incorrect vector, <1,0,0> So the profile is evaluating it against a square X plane hit, hence the tolerance bands not where you expect them.

Dump the cast points, you want the hits that comprise the circle with the correct nominal values and vectors. Instead of constructing a cast point from each individual hit, put all the hits directly into the feature set.

Yeah just went back and looked at the vectors of the cast points and yes they are wrong. Will redo that when I get a chance. Thanks everyone.
