I am having a problem with vector direction remaining the same while measuring a line I have attached a clip from the program. Here is some information pc-dmis version is 4.2 MR3 on a PC using windows XP pro and a faro 1/4" hard probe on a Faro arm, this problem occurs after alignment . This line measurement and hits were taken in the same direction even on the same side of the probe on the same edge of part which is a rectangular plate.
The problem is the way the software applies the probe radius and some times diameter.
