About Punch Axis Points
A punch axis point is a reference point that moves with a feature during both the unbend and bend back operations. You must set the punch_axis_points configuration option  to enable such points.
1. Placement of punch axis point, in Sketcher.
2. Cut with resulting punch axis point and datum point.
3. Unbent part, displaying actual positions of punch axis and datum points.

5. Datum point
Like a regular datum point, the punch axis point appears in the part, has a standard point symbol, and an assigned name (for example, PNT0).
Unlike a regular datum point, the punch axis point is not a separate feature. The point moves with the placement plane of its parent feature during the unbend and bend back operations. It is comparable to the feature axis in a revolved cut in part mode.
You can dimension to a punch axis point in detail drawings.
