Arc drawing
Arc drawing
(OP)
Does anyone know of a way in 2002, or any version for that matter, to draw an arc using the radius and the arc length? The closes I have been able to find is using the center, end, distance method but the distance is the chord length, not the arc length.
Any suggestions?

The best is just to get a cogo plug-in.

I wrote a lisp for something similar-you select a line or arcthat your new arc will connect to and be tangent to, then you specify radius, and either length or delta.
Email me at cab@eeiteam.com if interested.

2 steps, not one, but it's as close as I could find. Hope it helps.

Here is a Lisp I improvized just now. Hope it serves.
;to draw an arc by Center, Start and ArcLength
;www.homescript.com
(defun C:ARCLen()
(setq pcenter (getpoint "Center? "))
(setq pstart (getpoint pcenter "Start point: "))
(setq Radius (distance pcenter pstart))
(princ "\nRadius ")(princ Radius)(Princ "\n")
(setq Arclength (getreal "arclength? <CW minus>"))
(setq angle1 (* 180
(/ Arclength Radius PI)
))
(princ "\nAngle ")(princ angle1)(Princ "\n")
(command "_arc" pstart "_CE" pcenter "_A" angle1)
)
