How do I get an arc length and Rad from an ellipse in outocad

I'm trying to create an ellipse and then get an arc length and radius to determine the flat pattern before my material (mild steel) is rolled. Can anybody help please?

To my knowledge an ellipse does not have a radius...only circles have a radius.
And the arc lenght, just look at the properties of the curved line.
You'l find the lenght there...
