pretty much what "they mean" for automotive sheet metal is that they want the TOOLS built to pierce those holes normal to surface so it is round,... -

yeah, measuring a cylinder on a sheet metal stamping pierce hole, next to impossible. With .125" stock, you will probably have between 0.012"...Leave a comment:

I think that the train-wreck-driver needs to learn GD&T, especially is the 'cylinders' are pierce holes in that piece of sheet metal.Leave a comment:

never copy & paste features or dimensions in Pcdmis, each MUST have a unique ID (DIM ID or FEAT ID). Duplicates can and will mess stuff up real ...Leave a comment:

I go from 3.7 to 2016 and rarely back from 2016 to 3.7.
I do NOT use Xactmeasure. I measure automotive sheet metal, legacy dimensions, and...Leave a comment:

you should see some of the messes I get when I back-save.
I program in V3.7 on the old machine. Once the program is "SET", it...Leave a comment:

probably nothing that you did. SOME cad features don't back-save for crap. Simply delete the cad file of the back-save and re-import the IGES/STEP file...Leave a comment:

I don't think you are using the right workplane. All the points have the same X nominal, you should be either in the Y or Z workplane....Leave a comment:

WHOSE report is showing you these designations? Yours or a customers report? If a customers report is showing those, WHAT software are they using? ...Leave a comment:

if all you have are small holes that can vary a lot, then you would have at least 1 hole that would require the find hole or read position, if you have...Leave a comment:

You can also use REL_MEAS if you have a larger hole that is put in at the same time, same operation, as the hole you are 'finding'. If the larger hole...Leave a comment:

If you have the scan set to MASTER, no matter how you create it, the FIRST TIME it runs, it sets that as MASTER, as in NOMINAL. Set your scan to FIND...Leave a comment:

without the hand control, nope, you have to do it programmatically.Leave a comment:

there are setting in the probe-cal setup to control how far it 'moves above' the shank and how far it moves above in Z, you'll have to play with thos...Leave a comment:

Your CHECK should be something other than 0,0.

NOPE! It is defined as two different tools. TOOL_A will have a shank of 0,-.7071,-.7071 (down-pointing sphere, pointing to the front of the machine)...Leave a comment:

If you look at the qual-tool, it has a 'shank vector', in order of Pcdmis to miss the shank of the tool and move around the tool correctly, the shank...Leave a comment:

Did you change your QUAL TOOL information? If you change it's angular orientation, you MUST make a new tool with the correct vector.Leave a comment:

Not invalid, but not checkable. Basically, it means that your stamping die needs to pierce that hole normal to surface. I see it a lot. I have fixtures...Leave a comment:
