Question

Examlex · Accepted Answer

The Answer is The six conditions that apply when referencing coaxial diameters as primary co-datums MMB are:
1. The datum is an axis (line).
2. The axis of the datum feature simulators is the datum axis.
3. The datum feature simulators are fixed at the MMB size.
4. The part is oriented by the datum feature simulator.
