Compare two revisions of a drawing!!
I think this is a fantastic addition to AutoCAD based products such AutoCAD Civil 3D. You can now quickly review changes to drawing features such as 2D linework, Civil 3D objects (Pipes, Surfaces, etc), text, and pretty much anything within your drawings. It’s available in the main Application menu when no drawing is active or under Drawing Utilities when there is a drawing active. You can also access it from the new Collaborate ribbon tab.
Once you select DWG Compare, the dialog box will ask you to select which 2 drawings to compare, it will then create a third drawing with the two overlaid. Prior to selecting COMPARE, you can modify the color choices if you wish.
The results of the comparison are displayed in an automatically created third drawing. Three categories of objects, or parts of objects, are displayed – those which are located only in the first drawing (GREEN), those which are located only in the second drawing(RED), and those which are identical in the two drawings (GREY).
A contextual Compare ribbon tab lets you to control the appearance of results. This tab has three groups of controls–Comparison, Compare Filter and Change Set.
Again, this may seem like a simple task, but for quick reviews, client/city meetings and simple clashes, this tool is a great addition for 2019!
