Calculate Intersection Between Line and Triangle Net¶
Use this dialog to calculate intersection points between application layer lines and triangle nets.
Where can I find the dialog?¶
In the terrain model drawing context menu, select Tools - Calculate Intersection Between Line and Triangle Net.
Available Methods¶
The dialog provides four options:
- Trim or extend lines to intersection
- Split lines at intersection
- Create intersection points
- Move lines to intersection point
Trim or Extend Lines to Intersection¶
With this option, you can specify the direction in which the line should be trimmed or extended.
- First to last
- Last to first
- Both
For example, the First to last option means the direction is from the first point to the last point in the line.
Split Lines at Intersection¶
With this option, the lines are split at the intersection point.

The lines are split at the intersection point with the triangle net
The split lines receive values for the S_JOBRESULT attribute:
- S51: Intersection point in front of the surface
- S52: Intersection point behind the surface
You can use these values to set up a presentation that distinguishes the lines from each other.
Create Intersection Points¶
With this option, points are created where the lines intersect the triangle net.
