I was explained in PCDMIS CAD++ class that snap point is to correct machine drift mathematically not hiding machine drift (at least that the impression that I got). Example:Blue print defined a point on a complex surface at XY exact position (basic dimensions) and the third axis (Z) must meet blue print requirement at that position. The snap point does just that by re-calculating the actual Z value at exact position (theoretical position).
I remembered the instructor said he was helping one of his customers measuring a complex curve surface using CAD and the DCC of the machine is very sloppy, the part they were checking is a known good part but the result proved otherwise he then suggested to use snap point and everything fall in.
Your explanation is exactly the same as stated in PCDMIS help file.
I have read many of your postings and I know you are among the very best in the country, I have no doubt of your assessment. I am just confused!!!
It matches because I gave his explanation to WILCOX and they put it in the help file just as Hoedeman wrote it. Thats why. He's a smart cookie that ugly fuuck.
