This command fillets two segments of a 3D polyline with the given radius. AutoCAD's FILLET command does not support 3D Polyline entities. Since 3D polylines cannot have arcs, this command draws the fillet arc as a series of short chords. The elevations along the curve are interpolated from the 3D polyline.
