To Create a Radius-of-Curvature Dimension
The spline must have tangency defined before you can use a radius-of-curvature dimension.
1. Click Sketch > Normal or right-click in the Sketcher window and choose Dimension from the shortcut menu.
2. Click the spline endpoint.
3. Place the dimension with the middle mouse button.
* 
Ensure that the end point of the spline is tangent before applying this dimension.
