Draw Longitudinal Profile from Railway Model

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

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 () 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
   • Choose the source data for terrain profile - see Terrain Profile Settings for further details
   • Select the element/objects that are to be included in the profile presentation - see Illustration - Terrain Profile for further details
5. From other Novapoint design tasks
   • Select the design tasks which are to be included in the profile presentation - see From other Novapoint Design Tasks for further details
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

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'

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 () 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

A=	Terrain surface with breaklines	B=	Terrain surface without breaklines
C=	Wireframes: ✔ Wireframe surfaces are not considered for terrain surface for the setting with breakline. Alternatively, wireframes can be presented as individual objects using the option 'Existing Objects' ✔ Wireframe surfaces are presented as terrain surface for the setting without breaklines	D=	Terain (top layer/top soil)
E=	Subsurface layer (-1)	F=	Subsurface layer (-2)
=		H=	Vertical geometry of the alignment
I=	Calculation sections based on interval	J=	Calcualtion sections based on Extra Chainages (Surface breakpoints, intermediate break points, etc. (see railway model)

Water and Sewer

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

• Use the ellipse button () to open the dialog Water and Sewer
• Use the ellipse button () 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.
