Use LINEAR OPEN scan, click the START, DIRECTION, and END POINTS of the scan on the cad model.
Now comes the FUN part......
Your scan will wander all over UNLESS you make it a LINE, as in one axis needs to have the SAME number for all three points. You can change this maually by clicking on those points in the list in the scan dialog box. Once you have them all at the same value in one axis, you will need to tweak the VECTORS in the vector section of the scan dialog box. Make them all 0 or 1. Don't worry about what it will do, you just need to do it for the 'setup'. Once you have the 3 points and the vectors tweaked, THEN you click on GENERATE (which is what it was called for DECADES until some 'brilliant' coder decided to change it, not exactly SURE what the new name is, it may be calculate). Pcdmis will then go and generate all the hits (thus the original name of GENERATE!!!!) with all the correct vectors. When you do this, you will see the points being generated on the cad model. They will look like they are NOT on the cad data, but don't worry, they will be, the graphics show CENTER OF BALL path until it is all generated. Watch it generate the hits, some times Pcdmis will flip to the back side of the surface and go back to where it started on the INSIDE, if you see this, you will need to cancel and change the various tolerances for scan generation. If it generates it all correctly, then you will need to UN-MARK the measure now (YOU DO NOT WANT to measure it from the scan dialog menu). SET nominals to MASTER and set EXECUTE to normal IF you are using a touch trigger probe. If you are using a scanning probe, then you need to set it to FIND NOMS and RELEARN. Once you have this set, CREATE the scan (without measuring it) and close the scan dialog box. Repeat for as many 'strips' of scans as you need. Of course, it gets more complicated if the scans you want to make are not on the "peak" of the thing in an axis (like at 45 degrees) since the single axis number thing won't work.
