With DwgDiff, the comparison of CAD drawings becomes as easy as several mouse clicks. You can choose from several comparison methods and the appearance of the comparison results can be customized.

DwgDiff is a standalone tool and also an embedded module within CADCola. In the latter case, drawing comparison is strengthened by the version control functionality. As a result, the details of the change history, known as WHO, WHEN and WHAT, are recorded and can be tracked whenever necessary.

DwgView: exploring the structure of a CAD drawing

DwgView is an easy-to-use tool for both CAD developers and CAD operators, through which the structure of a CAD drawing becomes completely transparent. It can not only show the static structure of a drawing, but also dynamically track the changes performed by the user. With it, the study of AutoCAD programming is greatly accelerated and the miss of drawing operation is reduced to the most extent.
