Delete Ground

Delete all the points on a surface that fall within or "under" a particular terrace and its banks.

This function allows you to delete all the points on a surface, which fall within or "under" a particular terrace and its banks.

Since changes are not stored until the file is saved, you can recover from this operation by loading the file again and selecting No at the 'Do you want to save' prompt.

The function removes all surface points within the selected terrace. Unlike the Terrace Merge function, it does not attempt to link up any terrain lines, and it does not change the surface allocated to the terrace points.

Procedure

1. The Bank Surface Details display.

2. Fill in the relevant data and click OK.

3. You are prompted to:

Snap on terrace point

4. Click on one of the terrace points.

5. Once the terrace has been located, the following message displays.

6. Click Yes to delete the ground points under the terrace perimeter; or No to cancel the function.
