Convert to Arc Polyline

                                                                                         
Converts a 2D object into a Polyline composed of arcs. Any single-line 2D object can be converted. Objects like double lines, dimensions, and text must be exploded first before converting.

1. Start with a 2D object such as a polyline. This example uses a polyline consisting of both linear and arc segments.
2. To convert the polyline, select it and activate the Convert to Arc Polyline function. The Tolerance value sets the precision of the conversion; a small tolerance means high precision, and therefore more control points available for node editing.
