The default name of the new drawing is “Compare_DWG1 vs DWG2” (where DWG1 & DWG2 = the names of the two drawings being compared). Three categories of objects or parts of objects are displayed: those which are located only in the first drawing, those which are located only in the second drawing and those which are identical in the two drawings. The results of the comparison are displayed in a third drawing. Or you can use the browse buttons to select a drawing from the file navigation dialog. The drop list provides easy access to current and recently opened drawings.

If the current drawing has been saved, it is used as DWG1 in the DWG Compare dialog box. You can also access it from the new Collaborate ribbon tab: Having displayed this difference, you can decide whether to maintain the changes or change to the original design. All unchanged elements are shown in grey. The green and red graphics highlight the differences between the first version of the drawing ( green) and the second version ( red). With the Drawing Compare functionality, this is what you can see: What are the differences between the two drawings? Changes might be difficult to see but may be critical. For example, changes made to a schematic.

The New Drawing Compare tools in AutoCAD Electrical 2019 enables you to easily identify graphical visual differences between two revisions of any drawing.
