I need to specefy the radius of a segment or curve in a 2D schematical drawing.

Well... Notice that I mention that it is a free curve, meaning one that is not a segment or section of a perfect circle. but a curve that is not derive from a circle. that is way is a little bit more difficult. Im imagining that I have segment that curve and give individual radius to each segment but my question is more like what is the standard way of doing this when I am drawing a cad file for a factory to implement. I am not an engineer or an architect that's way... :)

In the 2D sketch, you draw an arrow starting from the center of the curvature of the arc. Imagine the circle that this arc would draw if you kept following it all the way around. The center of that circle is where you start the arrow. Start from there and draw an arrow along the radius to the arc and put the pointy end of the arrow to be on the arc. Off to the side near it, you write "r=12.5m" or whatever the radius is to whatever number of digits that you have for tolerance.

why is that so difficult? make a leader arrow from it and put your radius at the other end.
