Using simple offsets to create new polyline and polygon features

A simple offset is performed on a polyline or polygon and uses a specified offset distance. The offset distance can be based on an existing feature or other criteria such as distance from a the current GPS position.

Using a simple offset, you could, for example, map a line feature that is a given distance away from an existing line feature. You would then specify whether the new feature is left or right of the captured line.

Steps:
  1. Make the target layer editable using the Start/Stop Editing tool.

  2. Tap the drop-down arrow to the right of the Offset Point button.
  3. Tap Offset Polyline/Polygon.

    A red box around the Offset Polyline/Polygon button indicates that it is active.

    The Poly Offset dialog box is displayed.

  4. Tap the left or right checkbox to determine the relative position of the offset.

  5. Specify the Distance value.
  6. Tap OK.
  7. Tap the polyline—or polygon—button from the Feature Type drop-down list.

  8. Tap the screen where you want to begin your new feature and continue adding the required vertices.

    As you add vertices to your new line or polygon, a red line at the offset distance will be displayed. This is where your new feature will be created.

  9. Tap Proceed when you are finished capturing your new feature.

    The Feature Properties dialog box is displayed.

  10. Enter the information for the new feature.
  11. Tap OK.
  12. Your new feature is drawn at the specified distance of 20m from the existing polygon feature.

    TipTip:

    Using the snapping environment with offsets: You can set the snapping options so that your reference line, or capture line, snaps to an existing feature.
