Profile vs T-value vs Colormap

Hi,

Another day, another question Upside down

Today i had to check a profile callout (0.5 max - form only), but i find the results a bit strange, maybe i'm missing something but here is what i got :

- Profile is reporting OOT while point cloud colormap shows pretty good values (tolerance set to +/-0.25) while T-value shows something even different :

 

Where is the truth here ?

I would have think the values shown on point cloud are equal to the T-value no ?

For example here the point 88 is reporting 0.140 and T-value is 0.197, point 127 is reporting 0.152 and T-value is 0.068...

Also, if i look at all the values shown, the min is -0.034 and max is 0.155 so i would assume the profile result would be 0.189.

Any idea ?

  • I agree with  , based on that drawing, I wouldn't  have included the plane for the profile measurement because the leader line only points to the radius and does not include the all around symbol. 

    Either way (whether you include the plane or not), you need to do a full 3D best-fit alignment using the vector min/max fit on all of your measured points before reporting T values or creating the point colormap.  Only then would the results be equivalent to a legacy form only profile (again with the vector min/max fit) or a geometric tolerance profile command.
