AddCircle method draws wrong radius

[LewisA]

When I add a circle using the AddCircle method in IADSketchCircle it draws the circle by Radius/1.269999. For example, I put in Radius=1 and the sketched radius is: 0.7874016. My units are set for inches. If I scale the the radius*1.26999995936, I get the correct radius.

Any ideas???/

I found the answer. The default for dimensions passed in is centimeters.
