V3.7 MR2 - XP SP2

We inspect a planer suface on a part, construct plane.

We construct offset plane 3-1/2" from the inspected plane.

We inspect a hole through surface, use zero depth, thick = -.125

We inspect same hole zero depth, thick = -.5

We create a cylinder from the two circles.

We create a line from the two circles.

We construct an intersection point between the line and the projected plane

We construct an intersection point between the cylinder and the projected plane.

I measure the distance between the two constructed points.

Theoretical is zero, measured = .012

How can this be.

Both projected points use the same measured features,

Why is the projection of the cylinder and line different in measured value?

when they are defined by the same two circles.
