Alignment Features and Location vs Position

hello,

simple basics but i am not sure.

the ISO drawing callout's for GX circles, so i wrote the program only using GX circles... If i am not wrong the xact measure position calculation is also automatically using GX, even If the element is measured as GG ?!

Is this the right way, or should the alignment be GG to be more stable and measure the Elements a second time with GX, since our PC-DMIS 2017 and Q-DAS Converter can't output the Dimension when using Size for GX...

What i also can't figure out is, that the X,Y Location even with measured GX Features and alignment are not matching the XAct Location... ConfusedConfused

Perp. to centerline and the axis are checked so what could cause the deviation between the Position and Coordinates ?


Thanks in advance.

  • XactMeasure will report the Chebyshev flatness value, regardless of what math was used to measure the plane. The following screenshot was taken from PC-DMIS 2020 R1 and contains two plane - PLA-1.3 is a Least Squares BFRE plane and PLA-1.4 is a MINMAX (Chebyshev) BFRE plane. If you look at the report, you can see that the XactMeasure flatness results for both planes are identical and match the legacy flatness results for PLA-1.4.
