Drawing features from existing points

Use the CAD toolbar in Drawing mode to select existing points in the map and create coded linework between them. You can draw lines, arcs, and back-to-back arcs. You can also delete linework that you have created using the CAD toolbar.

  1. Tap the Draw line button .
  2. If required, tap the Start join sequence button and then select the feature code from the list of line feature codes defined in the feature library. The selected feature code is added to the Code field.
  3. In the map, tap the start point of the line sequence you want to create. The feature codes in the Code field are applied only to the start point. The feature code applied to the first point is also applied to the line.

  4. Continue to tap points until the line sequence is complete.

    As you select each subsequent point, a line is drawn between the two selected points and the first point is then deselected.

  5. To stop drawing lines, tap the Draw line button again.
  1. Tap the Draw arc button .
  2. If required, tap the Start join sequence button and then select the feature code from the list of line feature codes defined in the feature library. The selected feature code is added to the Code field.

  3. In the map, tap the start point of the arc you want to create.

    The points comprising the arc must have been observed consecutively. It will therefore not always be possible to join points with arcs.

  4. Continue to tap points until the arc sequence is complete.

    As you select each subsequent point, a red dashed line is drawn between the points until enough points are selected so that an arc can be drawn from the first point. As the arc is drawn the previous point is deselected.

  5. To stop drawing arcs, tap the Draw arc button again.

To draw a back-to-back arc, tap the Back-to-back arc button after completing the first arc and before selecting the second point of the second arc. After the first part of the arc is drawn between the first and second points of the arc, the button returns to the unselected state.

If you have joined points in a continuous line but want to break the line, select the point just before the break and tap End join sequence.

The End join sequence code is added to the Code field. The End join sequence code ensures the next point that has the same line feature code will not join to this line.

If the selected point was in the middle of a line, then the next point starts a new line.

  1. In the map, select the lines or arcs that you want to delete.

  2. Tap the Delete button .

  3. Select the feature(s) to delete from the list and tap Delete.

    Lines and arcs are deleted, and feature codes are removed from the affected points. However, the points remain in the job.
