convert spline to arc..?

Hai sir,
 
how can i convert a arc shaped spline to arc.?
i need to get the radius of that spline..is there any way to get the radius of arc shaped spline.?
ur helpings will be highly appriciated....
thanks

Basically, no. What you have to do is draw a three point arc over sections of the spline until you get them as close as you can to what you want. Then join them all to form a polyline.
 
Then you can get the radius of various sections, and there will be many.

Basically, yes. What you will have to do is -
Make sure you are in top view 2D wireframe shademode.
Run the Flatten command and accept the default No option when it prompts about removing hidden lines.
Run the Explode command on the lwpolyline resulting from the Flatten command.
You will now have a series of arcs.
Run the List command to retrieve the radii.
 
This is very useful for generating CNC G-code.

You can try out the new SPLINECAM app in Autodesk AppStore or download it from autocam2d.com/download link.
 
It converts splines to polylines/polyarcs with optimal number of vertices and smoothness.
