Oberon CurveWorks for CorelDRAW/Corel DESIGNER

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.

Now it's possible to do more technical-oriented graphic work without using AutoCAD or other expensive packages.


Oberon CurveWorks includes the following components:

  • Remove Overlap and Remove Intersections: remove overlapping areas of a curve:


  • Connect Curves and Join Curves: join open curves together to form a single closed curve:

  • Fuse Curves: joins open curves whose endpoints coincide.
  • Explode: breaks apart curves so each segment becomes an independent curve object.
  • Cut Curves: divides curves at each intersection point:

  • Fillet and Chamfer: create round/beveled corners for any cusp curve node:

  • Cleanup Nodes: removes any overlapping nodes
  • Curve Statistics: reports the total curve length and area as well as other curve information. (New: CurveWorks 1.3 introduces modeless dialog with ability to copy curve statistics data onto the system clipboard as text).
