Setting the Selection tolerance

A number of tools are used to interactively select features in your map documents:

They rely on a selection tolerance to select the desired feature when it is within a number of pixels of the cursor location.

Steps for setting the Selection tolerance

  1. Click Selection > Selection Options on the main menu.

    The Selection Options dialog box opens.

    Setting the Selection tolerance

  2. Specify the number of pixels you want to use as your selection tolerance when selecting features. A value of 3 to 5 pixels usually works well. A pixel count that is too small can be frustrating because it will be hard to precisely position and select features. However, too large of a pixel radius will result in inaccurate selections.

    Selection will not necessarily find the feature closest to the cursor; it returns the first feature in the dataset that is within the tolerance.
