Generate break lines between points.

This function allows you to generate break lines between points by indicating the first point and then the second.

Procedure

1. You are prompted to:

Break Line: Snap on start point

2. Click on an existing DTM point.

3. You are prompted to:

Break Line: Snap on next point

4. Lines are added continuously with single clicks. To break a string of continuous lines, right-click.

5. Press [Esc] key to end the function.

6. Adding a breakline over another breakline will remove the original breakline as crossing lines lead to an invalid model. The behaviour for adding a breakline over a feature line is similar, but because feature lines are regarded as a bit more permanent you are asked to confirm this.

This is an optional setting on the Terrain Options.
