profile of a line

[jessejames]

i have a profile of a line callout on a print it is to the centre of a groove using cad data i measured points on the inside an then the outside of the groove i created midpoints between the measured features,i took the midpoints an created a line i can see a deviation of approx 1.2 mils in the y value between the Theo an the Actt line but when i do the profile an get a very small error .07 i tried different workplanes what am i missing thx

Hard to say. Are you using Profile Form AND Location or Form ONLY?

I believe the question to you JesseJames was: Are you using Profile Form AND Location or Form ONLY?


There's a BIG DIFFERENCE...

OK, I want to get this straight.

You picked points from a model and measured them so you KNOW the nominals are correct.

You constructed mid points from two sets of points (presumably 'diametrally opposed' or as close as you can get). Since the original points taken from the model are defined correctly then you KNOW the midpoint set is defined correctly.

You construct a line from all the midpoints you just constructed.

You profile this line and graphically is shows up as 1.2mm but reports as 0.7mm?


OK, when you construct this line which plane do you construct it in?
