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.
