CompareDWG finds the differences between two revisions of an AutoCAD drawing. This program is available for all full AutoCAD versions.

CompareDWG Features

  • Find the differences between two revisions of an AutoCAD drawing.
  • In Detailed Mode, compare the complete AutoCAD internal representation of a drawing, not just the graphical appearance.
  • In Basic Mode, compare the drawing graphics only (no matching AutoCAD handles are needed).
  • Display the differences in AutoCAD, using contrasting colors for Added entities, Deleted entities etc.
  • Choose your own markup colors, a legend can be created automatically.
  • Save the differences to separate files. This creates for example a DWG file which contains all new entities.
  • Create reports on the types and quantities of the entities found in the drawings.
  • Compare table entries (layers, linetypes etc) and present the differences in a report.
  • Compare drawing variables.
  • Include CompareDWG in your own LISP applications.
  • Also works for Architectural Desktop and Autodesk Map, but not for Mechanical Desktop or Inventor.
