add and subtract radii

[Mark Boardman]

Fairly new to IM Inspect.

I need to measure from a plane to the outer radius of a cylinder (or a circle), not just to the centre axis (or point).
How do i do this?
In my CMM software I simply select 'add radius'.

Thanks,
Mark.

Found this inelegant solution. Any better ones?
Construct 2 end points at the ends of the cylinder
Construct a line from the plane to one end point
Intersect the line and the cylinder to make two points on the edge of the cylinder.
Measure from the plane to the points.........
