Contacting Feature (CF) for datum systems

[[Ma...]]

Hi

Are there any suggestions how to evaluate contacting features in Zeiss Inspect 3D 2025 according ISO 5459 (e.g. Rule 5 and Annex Example 1)

In the attached picture the datum B should not be the axis of the hole, but the contacting line given by B1. Hence the specification of B[CF] in the profile tolerance.

I was unable to find any ideas in the help or here in the forum.

Thanks for any inputs.

Martin
