True Position of holes, without Diameter symbol in Control Box??

Just wanted to point out that pcdmis evaluates the position of a cylinder over its defined length, regardless of where you take the probings. So as long as you've defined the cylinder to cover the entire length of the feature, it will be evaluated over the entire length. This can be good and bad (mostly good), but its important to know.

So if the cylinder is say 1.00" deep and is not a thru cylinder/Ø and you probe that cylinder at 3 levels 1.) .020" 2.) .500" 3.) .800" even though there is .200" of that cylinder that has had no probe hits it's TRULY being defined over the length. I agree that DMIS does attempt it but it is calculations based on the points taken.

If I am measuring a cylinder that has been created by circle interpellation and the tool breaks down as it reaches that last .200" of the cylinder depending upon where I probe that cylinder will determine if that is detected. I understand and agree with the standard but DMIS can only calculate with data it is given and the data is coming from where the probe touches the part. This is why I suggested that I would want to know the function of the feature, so that I can inspect it at the appropriate level. It's the same on surface profiles. I can take a point every .100 on a grid but it can still miss excess material from the machine that just happend to jump one line of code while 3D'ing a surface leaving a .030" x .030" stripe across the part or a chip that causes a gouge on one pass of the tool. I have no claims to being an expert, it's just the way my mind see's it, and I truly mean no offense to anyone.
