Review the differences between the current drawing and a specified comparison drawing.
- Open the first drawing you want to compare with another drawing.
- Click DWG Compare on the toolbar.
- In the selection dialog box, specify the drawing file that you want to compare with the current drawing and click Open.
The DWG Compare visor opens and the comparison results display in the current drawing. This visor provides several commands and options to review and control the comparison result.
Differences between the comparison drawing and the current drawing are grouped by proximity into
change sets that are surrounded by revision clouds. Differences are separated by color. By default, the colors are assigned as follows:
- Red - Objects that are only in the compared drawing
- Green - Objects that are only in the current drawing
- Gray - Objects that are common to both drawings
Note:
- If you have a layer that is turned off or frozen in your current drawing, it will not become part of the comparison result.
- Any changes you make in the comparison drawing do not display in a comparison until you save the changes in the comparison drawing.
- You can start the DWG Compare utility from the File menu even when you don't have any open drawings. In the DWG Compare dialog, specify the base and reference drawing, and click Compare. The comparison result is shown in the base drawing.

Copy Objects From the Compared Drawing to the Current Drawing
- Click Import Objects to import selected objects from the compared drawing into the current drawing.
- Select the objects in the comparison that you want to copy into the current drawing and press Enter. Only those objects that are not in the current drawing can be imported.
The objects you selected from the comparison are copied into to your current drawing and no longer differ between the drawings.
Export a Snapshot Drawing to Save the Differences
- Click Export Snapshot to combine the two comparison drawings into a new
snapshot drawing file for further review.
- In the Export a Comparison Snapshot dialog box, click Continue.
- Save the drawing file. By default, the file name is Compare_Current Drawing vs
Compared Drawing.dwg
This operation creates a drawing file displaying the differences between the two files. In the snapshot drawing, the two drawings in the comparison are stored as blocks.
End the Comparison
- Click to end the comparison and close the DWG Compare visor.
