Eliminates points from dimensioning consideration when multiple pairs of points are equal distances apart (for example, when multiple objects are placed in a grid pattern). If you select the Keep Equal Distance Duplicates check box, multiple dimensions with identical values might appear on the drawing.
The Default (DrawingGeometricAnalyzer) geometric analyzer module uses the Keep Equal Distance Duplicates property.

In the following example, the software examines the points at the same Y location, and traverses them horizontally to find and eliminate points that are equal X distances apart from dimensioning consideration. The software retains only the two leftmost dimension connect points because the other pairs of points are equal distances apart.

Likewise, the software examines the points at the same X location, and traverses them vertically to find and eliminate points that are equal Y distances apart from dimensioning consideration. The software retains only the bottom two dimension connect points because the other pairs of points are equal distances apart.
