Hello, I am wondering, why the value of RMS in the Surface Sag tool does not correspond to the RMS value set inside TEZI operand in the tolerance data editor. The values are quite similar (for example, RMS inside TEZI set for 1e-6 and RMS in the Surface Sag is 1,093e-6). Surface is spherical, so i just remove base radius in the Surface Sag tool. Regarding the TEZI documentation, both values should be identical. Better sampling of the sag also does not help.
