How do I easily explode a spline into lines and arcs. I have a group of splines that I keep exploding. They have nested splines within splines. I keep exploding these nested splines until I get down to "simple" splines that seem to have only one primitive element within them, like 1 line or 1 arc. Then the explode command doesn't explode any further. I've seen a trick to convert splines to 3D polylines by saving the drawing to DXF R12, then reopening and resaving as DXF 2000. The problem is, this breaks what looks like simple arcs into very small lines. I want to try to keep the larger arcs intact. Any info would be appreciated.
