Specifies which rail lines are generated. Select Left Rail, Centreline and/or Right Rail.
Required Lines
Specifies which rail lines are generated. Select Left Rail, Centreline and/or Right Rail.
Object Type
Specifies the object type that is used for the generated rail lines. Select either 3D Polyline or Feature Line. Use 3D Polyline for quicker generation and performance.
When you select Feature Line, you can specify names for each generated rail line. Each rail line (Left, Centreline and Right) receives a system-generated name. To edit the name template, click 
.
Alignment
Specifies the parent rail alignment from which to create the rail lines. Click to change the alignment.
Profile
Specifies the parent profile to use for the rail lines. Click 
to select a profile from the drawing.
Distance Between Rails
Specifies the distance between the left and right rail lines.
Chainage Range
Specifies the station range of the rail lines in relation to the parent alignment. Select From Start to generate the rail line from the parent alignment start station. Select To End to generate the rail line to the parent alignment end station.
You can also specify stations for the start and end points of the rail lines. Clear the From Start and/or To End options and then enter station values directly in the fields. Alternatively, you can click 
to select a station in the drawing.
Creation Method
Specifies the intervals or tolerance used for adding vertexes along the rail lines.
- Interval
- Select Interval and click the Interval
button to open the Interval Settings dialog box. - Tolerance
- Select Tolerance and enter a tolerance value in the field. If you want to add additional vertexes, click the Tolerance Settings button to open the Tolerance Settings dialog box. Vertexes are created for all cant, horizontal and vertical critical geometry points and user defined points and sample line stations defined along the alignment. This guarantees that critical points on the alignment are always accurate. Once the vertexes are placed, the distance between the parent alignment and the midpoint of each segment along the rail line is checked. If this distance falls outside the specified tolerance value, the rail line segment is split in half and both segments are rechecked.
