Setting options for streaming

When streaming, there are several options you can set to control where vertices are created. The interval at which points are created when streaming is called the stream tolerance. Because the default stream tolerance is zero, you must enter a tolerance value before you start digitizing, or the vertices will join together or overlap each other. You can change the stream tolerance at any time, even when you are in the process of digitizing a feature.

You must also specify the number of streaming vertices you want to group together. The number you set tells ArcMap how many vertices to delete when you click the Undo button. For example, if you set this number to 20 and click the Undo button while you are digitizing a feature, ArcMap deletes the last 20 digitized vertices from your feature.

  1. Click the Editor menu and click Options.
  2. Click the General tab.
  3. Type the stream tolerance (in map units). You can also give the stream tolerance value in other units by specifying a distance units abbreviation with the value that you enter. For example, to specify a distance of 10 feet, type 10ft. Distance unit abbreviations only work if your data frame is projected.
  4. Type the number of vertices you want to group together. Now when you click the Undo button Undo while digitizing in stream mode, the number of vertices you specify are deleted.
  5. Click OK.
