Place Trench

You can access this dialog from the following:

Ribbon: OpenRail Modeling > Rail > Miscellaneous > LV Assets

Trench Attributes section is the attached Item Type defined in the selected Feature Definition.

The Place Trench tool will place a Trench by three methods:

Trench with a start- and end station measured form a selected centerline. Horizontal offset is defined by Offset Mode/Offset.
- Elevation is constant for the whole trench, according to Elevation Mode/Elevation
Trench Start- and Endpoint a free data-point
- Elevation is constant for the whole trench, according to Elevation Mode/Elevation
Trench Start- and/or Endpoint is a snapped point (existing Trench or Connection Point). The snap-point will set the start-station and horizontal offset if a centerline is selected. If not selecting a centerline and snapping to an existing trench or Connection Point, the snap-point's XY coordinates will set the Trench start- and/or endpoint.
- The snap-point's elevation has priority and will always be used. A snap-point will automatically change the Elevation Mode to Absolute and apply the snap-point's absolute elevation value to the Elevation control.

If both the Trench's Start and Endpoint are snapped, elevation will be applied to the Start and Endpoint individually.

Trench UI Controls

Setting	Description
Location	Start Point Distance - station value for the start-point. End Point Distance - station value for the endpoint. Offset Mode - perpendicular (horizontal) offset from a centerline. Offset from Centerline Offset from Closest Rail Offset - perpendicular (horizontal) offset value.
Elevation	Elevation Mode - Trench elevation, used in 3D model. Absolute - Z-coordinate Relative Active Terrain Model - Elevation relative to the active terrain model Relative to Centerline Relative to Closest Rail - Cant will be considered Elevation - Elevation value.
Feature	Feature Definition - Trench Feature definitions. Name Prefix - Feature name.

A placed Trench has end-manipulators. To visualize end-manipulators, select a trench with MicroStation Element Selection. End-manipulators has following capabilities:

Stretch or shrink the trench by dragging the horizontal arrow
Increase or decrease horizontal offset by dragging the horizontal arrow
Move the trench endpoint by dragging the dot
Horizontal offset can be changed by clicking on the offset value

Properties

The Trench object has the following Properties:

Trench properties except for the Start Offset Mode, End Offset Mode and Elevation Mode can be edited.

Note: Properties will differ depending on how the Trench is placed.
