Dimension length of curve
Dimension length of curve
(OP)
Hello:
I would like to know if it is possible to dimension the length of a curve in AutoCad, for example, 1/4 of the circumference of a circle.
It is possible in other CAD programs, but I cannot seem to accomplish it in AutoCad.
Thank You

They should add it to AutoCad's dimension function.
