Trenches, Ditches

In Kubla Cubed, two key elevation elements are useful for defining trenches.

Trench Element:

When using the Trench element, set the depth by using a positive value. The Trench element is a relative element, so the values are specified as 'depths'.

Style of Trench:

With some small changes, you can adjust the appearance of a trench. After defining a centreline and setting the depths, adjust the Width of the trench and Side Batter to generate different styles of trench. Three examples are shown below:

The below image displays the cross sections of the three trench elements (above) giving another perspective of the differing Widths and Side Batters.

Note: In cases where two trenches intersect, the depth value from the trench with the greatest depth at the point of intersection will be used.

2. Path Element:

To define trenches using absolute elevations, use the Path element.

Draw the centreline (points on the line without a value will be interpolated).
Set width and side batters. To create a V trench, set width to 0.
If two paths intersect, the one with the higher depth will take precedence.

When using the Path element, if you leave an elevation blank, it will interpolate from the neighbors. For a constant elevation, set the same value at the beginning and end, leaving the others blank or marked as 'not set.'
