That a great question. We can utilize a datum target area. Which will essentially be a 50mm diameter circle drawn directly on the drawing with hatching inside the circle. The circle size is dimensioned on the drawing with a basic dimension of 50mm. And the flatness callout will point to that area, indicating that the flatness only applies to the hatched area.
Very helpful video sir 🙏
How do I apply flatness to just an area? Example 50mm diameter from the center of 100mm round plate
