Edit Feature Settings – Rail Dialog Box

Use this dialogue box to view and change the default settings for rail-related objects.

Rail Line Options

Rail Line Object Type

Specifies the object type used for the generated rail lines. Select either 3D Polyline or Feature Line.

Distance Between Rails

Specifies the distance between the left and right rail lines. Click in the Value column and enter a length or click and select a length in the drawing.

From Parent Alignment Start

Generates the rail line from the parent alignment start station. Select Yes or No.

To Parent Alignment End

Generates the rail line to the parent alignment end station. Select Yes or No.

Creation Method

Specifies how the incremental vertexes are added to the rail lines. Select either Interval or Tolerance.

Create Left Rail

Generates a rail line to the left of the parent alignment. Select Yes or No.

Create Centre Rail

Generates a rail line on the parent alignment. Select Yes or No.

Create Right Rail

Generates a rail line to the right of the parent alignment. Select Yes or No.

Interval Settings

Alignment - Along Straights

Specifies the insertion frequency for vertexes along the straight portions of a rail line. Click in the Value column and enter a length or click and select a length in the drawing.

Alignment - Along Curves

Specifies how the frequency for inserting vertexes along curves is determined.

• By Curvature: Horizontal baseline curves are tessellated using the Mid-Ordinate Distance To Define Curvature value. Stations are created along the tessellated curve at each point where the tessellation touches the curve, as shown in the following illustration:
  
• At An Increment: Stations are placed along the curve at the value specified in the Curve Increment field.
• Both: Uses both the By Curvature option and the At An Increment option.

Alignment - Curve Increment

Specifies the insertion frequency for vertexes along curves. The Along Curves setting must be set as At Increment or Both to change this setting. Click in the Value column and enter a length or click and select a length in the drawing.

Alignment - Mid-ordinate Distance to Define Curvature

Specifies the mid-ordinate distance for the rail line segments along curves. Click in the Value column and enter a length or click and select a length in the drawing.

Alignment - Along transitions

Specifies th insertion frequency along the spiral portion of an alignment. Click in the Value column and enter a length or click and select a length in the drawing.

Note: This setting is not used when a feature line is specified for the horizontal baseline.

Alignment - At Horizontal Geometry Points

Specifies whether the vertexes should be inserted at horizontal baseline geometry points where the horizontal baseline geometry changes (such as the start of a curve).

Alignment - At Cant Critical Points

Specifies vertexes on the rail line that correspond to the cant critical points on the parent alignment.

Alignment - At Mid of Curve

Specifies vertexes on the rail line that correspond to the mid-curve points on the parent alignment.

Alignment - At Sample Line Group Points

Creates vertexes on the rail line that correspond to existing sample lines along the parent alignment. Click in the Value field and specify the sample line group to use.

Profile - Along Profile Points

Specifies the insertion frequency of vertexes along curve portions of the profile geometry. Click in the Value column and enter a length or click and select a length in the drawing.

Profile - At Profile Geometry Points

Specifies whether the vertexes should be inserted at vertical baseline geometry points where the vertical baseline geometry changes.

Profile - At High/Low Points

Specifies whether the vertexes should be inserted at the high and low points of the vertical baseline geometry.

Tolerance Settings

Tolerance

Specifies the default tolerance to use when you select the Tolerance option in the Rail Lines dialog box. Click in the Value column and enter a length or click and select a length in the drawing.

Default Styles

Feature Line Style

Specifies the default feature line style applied to platform edges. Click in the Value column and click to select a feature line style from the Feature Line Style dialog box.

Left Rail Feature Line Style

Specifies the default feature line style applied to the left rail line. Click in the Value column and click to select a feature line style from the Feature Line Style dialog box.

Centre Rail Feature Line Style

Specifies the default feature line style applied to the middle rail line. Click in the Value column and click to select a feature line style from the Feature Line Style dialog box.

Right Rail Feature Line Style

Specifies the default feature line style applied to the right rail line. Click in the Value column and click to select a feature line style from the Feature Line Style dialog box.

Default Name Format

Feature Line Name Template

Click in the Value column and click to define the naming parameters for the feature line from the Name Template dialog box.

Left Rail Line Name

Specifies the default name format for the left rail line. Click in the Value column and click to define the naming parameters in the Name Template dialog box.

Centre Rail Line Name

Specifies the default name format for the middle rail line. Click in the Value column and click to define the naming parameters in the Name Template dialog box.

Right Rail Line Name

Specifies the default name format for the right rail line. Click in the Value column and click to define the naming parameters in the Name Template dialog box.

Platform Edge Options

Use Platform Length

Specifies if a user-defined length is applied when calculating a platform edge. Select Yes or No in the Value column.

Default Length

Specifies the default length to use when Use Platform Length is selected. Click in the Value column and enter a length or click and select a length in the drawing.

Chainage Interval

Specifies the default distance between chainages of the platform edge. Click in the Value column and enter a length or click and select a length in the drawing.

Track Gauge

Specifies the default distance between the inner faces of the two rails of the parent alignment. Click in the Value column and enter a length or click and select a length in the drawing.

Platform Height

Specifies the default distance of the platform edge above the rail when calculating simple geometry for platform edges. Click in the Value column and enter a length or click and select a length in the drawing.

Offset from Carriage

Specifies the default offset distance from the platform to the carriage. Click in the Value column and enter a length or click and select a length in the drawing area.

Safety Tolerance

Specifies an additional offset from the carriage to the platform to accommodate movement of the carriage when calculating simple geometry for platform edges. Click in the Value column and enter a length or click and select a length in the drawing.

Carriage Length
