This function lets you recreate a vector graphic as bezier curves, using one of three tolerance settings: Tight, Medium or Loose.
Recreate with Bezier Curves is part of the Data Clean Up Tool, but it is also available as a stand alone tool in the LED Menu.
The Tight setting will give results that are the most faithful to the original artwork, but with more vectors. The Loose setting will deviate more from the orginal path, but with fewer vectors. The Medium setting will be in the middle.
This function is useful to clean up artwork that may have an excessive number of vectors, perhaps as chords, or very poor or jagged vectors.
