I need to convert an arc shaped spline to arcs. Is there a "simple" way to do so other than tracing over the contour with arcs. The end goal is to be able to get the spline into a form that our CNC will recognize. I'm using AutoCADLT 2008.

Have you searched on here for the Spline-to-Pline.lsp?

SLW, he's using LT. No lisping allowed.

Jthom, even if you could use a lisp routine to convert the spline to a polyline, you would not get arcs, only polyline segments. You will need to just trace over your polyline to get the required arcs you need.

Sorry, my brain isn't cooperating with me today. :?

You can "dxfout" the spline (drawing) to a R12 version; splines will be coverted to polylines. If desired, explode that to a series of short line segments.

Once you have it as a polyline, you can Double-Click it and choose the FIT option to get back some curve. Don't know how accurate it will be.
