Draw Longitudinal Profile from Railway Model

Use this function to present the longitudinal profile for the alignment of the active railway design task.

Procedure

Open the dialog Draw Longitudinal Profile from Railway Model

MOUS_ICO Toolbar: Draw Longitudinal Profile > Draw Longitudinal Profile from Railway Model Draw Longitudinal Profile from Railway Model
MOUS_ICO Menu: Railway > Draw Longitudinal Profile > Draw Longitudinal Profile from Railway Model Draw Longitudinal Profile from Railway Model
MOUS_ICO Ribbon: Railway > Draw: Draw Longitudinal Profile from Railway Model Draw Longitudinal Profile from Railway Model

The active railway design task and start/end chainages (extents) of its alignment are displayed. To change the railway design task, exit the function and run the function Select design task.

  1. Longitudinal Profile Settings - define Start Chainage and Datum
    • These two parameter refer the lower left corner of the inner frame (profile area) - see frame for inner frame
    • Start chainage of the alignment is the default value but can be out side the start chainage of alignment
    • Define the insertion point - see frame
    • Pick the insertion point using the ellipse button (Pick) OR key-in the coordinates at X and Y
  2. Frame Settings
    • Define Frame Length, Frame Height, and Vertical Exaggeration
    • Start chainage, datum, frame length, frame height, and vertical exaggeration define the inner frame - see frame
  3. Alignment Chainage Settings - define the section of alignment for profile presentation
    • Default section - extents of inner frame i.e., from start chainage (defined at Longitudinal Profile Settings) to start chainage plus frame length (defined at Frame Settings)
    • Use these options to change the section from that of inner frame
    • The values can be outside the inner frame / extents of alignment but profile shall be limited to the extents of alignment
    • Preview of profile area is displayed at Location Selection Preview
  4. Terrain Profile Settings
  5. From other Novapoint design tasks
  6. Drawing Style Settings - Choose a drawing standard from the predefined standards for longitudinal profile
    • Preview of the profile with the active profile drawing style is displayed at Longitudinal Profile Preview
  7. Execute the function with the button Draw
Tips:
  • Relevant help text (quick help) for the active parameter is displayed at the bottom of the dialog
  • Double click on the parameter set heading OR single click on the + / - sign to expand / collapse the parameter set

Terrain Profile Settings

Choice to present the surface of the existing wireframes (other road, railway, etc. projects) as terrain surface.

  • Prerequisite:
    1. Wireframes available in the Quadri model at the instance of calculating the railway
    2. Only the wireframes crossing the alignment shall be considered
    3. 'Groups and Feature Code Settings' at the instance of calculating the railway
  • The choice terrain surface doesn't treat the existing wireframes as terrain surface while the choice surface for quantity calculation treats them as terrain surface - see 'Illustration - Terrain Profile'
Note:
  • The calculation settings of the railway model controls the precision of terrain surface following the surface of wireframes
  • Refer the following for calculation settings of the railway

The following options are available:

  • Terrain source - Select With breaklines to draw the original terrain and included wireframe models, drawn separately. Select Without breaklines to draw from the cross section calculation only.
  • Wireframes - Wireframes crossing the alignment
  • Other alignments - Other alignments crossing the alignment of the active railway design task
    • A vertical line with a leader (to point the elevation) and label represent the crossing alignments
    • A label for alignment name, chainage, and elevation is also drawn
  • Terrain offset - Terrain profile at an offset from the alignment (left side and/or right side)
  • Existing Objects - Mark the check box to include these additional objects in the presentation.
    • The cross-section of these will be as per the parameters defined in dtm_objects
    • A label for size (height/diameter), chainage and elevation is also drawn
  • Rehabilitation - If layers for rehabilitation has been defined, these can be included here. Se also Rehabilitiation.
  • External alignments - The vertical geometry of desired alignments will be projected to the profile being presented.
    • This feature displays the vertical geometry of other alignments in the same profile
    • E.g., Vertical alignment of Ramps, Interchanges, etc. in the profile of alignment of active railway model
    • Use the ellipse button (Quadri lines) to select the alignments (having vertical geometry) available in the active Quadri model.
    • The dialog Quadri Lines will pop up with the list, mark the check box, and click OK
Note:
  • The result is influenced by the following:
    1. Wireframes, alignments, existing objects, etc., that were available in the Quadri model at the instance of calculating the railway design task
    2. Groups and Feature Code Settings at the instance of calculating the railway design task

From Other Novapoint Design Tasks

Choose the the design tasks and define the settings to include them in the profile presentation

Water and Sewer

Mark the check box, to include the water and sewer elements in the profile presentation.

  • Use the ellipse button (Open) to open the dialog Water and Sewer
  • Use the ellipse button (Open) to select the water and sewer project (*.NCP file)
  • Trench: Select the trenches from the pull down menu and click OK

Tunnel Profile Lines

Mark the check box to include the tunnel profile lines in the profile presentation.

  • Use the ellipse button (Open) to open the dialog Draw Tunnel Profile Lines
  • Current Railway Model - read from Select design task.
  • Tunnel Geometry File - use the ellipse button (Open) to select the tunnel geometry file (*.XML file)
  • Chainage Calculation Interval - Defines the interval for tunnel cross-section calculation
    • The cross-sections at these sections are accurately calculated and tunnel profile lines are generated by linear interpolation among the sections
  • Surfaces - Choose to present profile lines for inner surface, outer surface, OR both surfaces of the tunnel
  • Extreme Points - For the choice made at 'Surface', further selection options for the point(s) along which profile lines are to be generated and presented
    • Select the extreme points and click OK
Note:
  • Ensure that the tunnel project has been designed for this railway model as the tunnel profile lines will be recalculated considering the specified tunnel geometry file and the railway model
  • The extreme points are calculated for a vertical/horizontal coordinate system (not rotated)
  • This means that if a symmetrical tunnel is rotated, the extreme top point is the point at the maximum elevation but not the point on the symmetrical axis
