Tools > Cleanup > Select Duplicates (select from Main Menu)
Select duplicate objects.
This function selects duplicate objects (i.e. underlying object(s) with same geometry) based on the criteria set in the ensuing Select Duplicates box:
Some important aspects to note:
•The objects must all be selected before conducting the duplicate analysis. This can be accomplished via the rectangular selection tool (on the Quick Access Bar).
•Either exact duplicate objects (in terms of geometry and properties such as colour) can be selected or almost exact duplicates based on a tolerance factor. The latter, may be slightly different objects and still considered duplicate. The amount of difference allowable depends on the value entered. A higher value allows more significant differences. If Objects must match exactly tick box is ticked, then the two tolerance input boxes are disabled.
•The Selection results can be set so that:
o all duplicates are selected in a group
oor all except the first one encountered in the group
o or only the first duplicate found in the group
