How can I set the length on this curve? I don't want the radius but rather the length on the curve. I tried path length in smart dimensions but it doesn't allow only one path sketch.
If it is a circular arc (you have not shown your curve) then you click the arc and then its two endpoints to dimension its length.
It is a 3 point arc. Could you show what you mean.
Did you try it?
It worked. Thanks

If it is a spline,
then draw a separate straight line somewhere (in the same sketch) and select the line and the spline and select "equal curve length".
Then add a dimension to the line length:
It's not a spline. It's a 3 point arc.
