The DWG Compare dialog box is displayed. Select the drawing files you want to compare and click Compare.
The
COMPARE command provides you with a visual comparison between different revisions of a drawing or different drawings, and then review those changes. During the comparison process, it identifies objects that have been modified, added, or removed in the review drawing. The default two-color comparison mode uses green and red to highlight the differences. You can change the default highlight colors for the two drawing files in comparison. The unchanged objects, in the comparison drawing, are highlighted in a default gray color. By default, the file name of the comparison drawing is
Compare_<first drawing name> vs <second drawing name>.dwg and is an unsaved file. You can choose to rename the drawing file before saving it. The comparison drawing is always set to plan view.
The DWG 1 and DWG 2 are inserted as blocks into the comparison drawing. In the comparison drawing, the differences are highlighted, as change sets, using revision clouds. Revision clouds are created on a new layer, in the comparison drawing, named 0-Markups. The number of differences in the two drawing files determines the number of revision clouds. By default, rectangular revision clouds are used to highlight the differences. You can use these various comparison options for reviewing the comparison drawing:
View – You can change the display order and object visibility in the comparison drawing from the compare ribbon contextual tab.
Filter – You can use the text and hatch filters to show or hide these objects in the comparison drawing. By default, text objects are always included in the drawing comparison.
Change set – You can change the type of revision cloud for your change set, control the offset distance between the bounding box to the rectangle used for creating the revision cloud, and navigate through the various change sets in the comparison drawing.
