### GrePartialArc - Remarks

Upon completion, the current (X,Y) position is the end of the partial arc. The dimensions of the full arc are defined as a multiplier, which is applied to the current arc parameters. The partial arc that is drawn is the section of the full arc that is enclosed by the specified start and sweep angles.

If GrePartialArc is used within a path or an area definition to continue a figure following a GreBoxxxx or GreFullArcxxx function, the error PMERR_INV _NESTED_FIGURES is posted. This error occurs because GreBoxxxx and GreFullArcxxx generate a closed figure within an area or path definition.
