To Work With the Comparison Drawing

Use the various comparison options to review the comparison drawing.

• In the DWG Compare dialog, select the two drawings files you want to compare and click Compare. A contextual ribbon tab displays.
• Use the options described below to review the comparison results.

Draw Order

Draw Order allows you to control the display of overlapping objects in your comparison drawing.

• Click Compare contextual ribbon tab > Comparison panel > Draw Order to swap the display order of the overlapping objects from the two drawing files.

  By default, the DWG 1 objects are in front and DWG 2 objects are in back.

Visibility of Compared Objects

• In the Compare contextual ribbon tab > Comparison panel, click the light bulb next to the DWG file to toggle the visibility of the objects from that DWG file.

  By default, all the supported objects from the compared drawings, are visible in the comparison drawing.

• In the Compare contextual ribbon tab > Comparison panel, click the light bulb next to Common To Both to toggle the visibility of the objects that are the same in both of the compared drawing files.

Drawing Information

Drawing Information provides you with some basic file information about the two DWG files used for the comparison.

1. Click Compare contextual ribbon tab > Comparison panel > Drawing Information.
2. In the Information about Compared Files dialog box, you can select from the following:
   • Insert in the Drawing. Inserts the information about the compared drawing files in to your current drawing in a table.
   • Copy to Clipboard. Copies the information about the compared drawing files to your clipboard for pasting on the drawing as mtext or to another application.

Filters

Filters allow you to hide the comparison results for certain objects.

• To hide text comparison, click Compare contextual ribbon tab > Compare Filter panel > Text.
  Note: By default, text comparison is set to 1 (on). You can change the default value to 0 (off) using the COMPARETEXT system variable.
• To hide hatch object comparison, click Compare contextual ribbon tab > Compare Filter panel > Hatch.
  Note: By default, hatch comparison is set to 0 (off). You can change the default value to 1 (on) using the COMPAREHATCH system variable.

Revision Clouds

Revision clouds are used on the comparison drawing to highlight the differences between the compared files.

• To toggle the visibility of the revision clouds, click Compare contextual ribbon tab > Change Set panel > Revision Cloud.
  Note: By default, revision cloud visibility is set to 1 (on). You can change the default value using the COMPARESHOWRC system variable.
• To change the shape of the revision clouds, select Rectangular or Polygonal from the Compare contextual ribbon tab > Change Set panel > Revision Cloud > Revision Cloud drop-down.
  Note: By default, the revision cloud is set to 0 (rectangular). You can change the default value using the COMPARERCSHAPE system variable.
• To change the offset distance between the boundary of the change sets and the revision clouds, use the Margin slider on the Compare contextual ribbon tab > Change Set panel.

  The higher the margin value, the bigger the boundary that contains the differences, which results in a bigger revision cloud. You can change the default value using the COMPARERCMARGIN system variable.
