Oberon CurveWorks is a set of professional quality macros for working with curves in CorelDRAW and Corel DESIGNER. These macros add some missing CAD features to CorelDRAW/Corel DESIGNER and help improve document editing workflow. This program requires CorelDRAW 10 Service Pack 1 (10.427) or later. Correct functioning under the original release of CorelDRAW 10 (10.410) is not guaranteed. This program will not run under earlier versions of CorelDRAW.
