Novapoint Road Library

Use this function to draw the terrain cross-sections along the desired (source) line. The cross-sections will be drawn in one column. The source line can be:

1. an alignment/object from the terrain model
2. an ASCII file with the alignment data (*.TIT, *.LIN, *.DAT, *.INH, and *.LI)
3. a line/arc/polyline or alignment from the current drawing

Run the function from the following locations:

MOUS_ICO Toolbar: Draw Cross-sections:  Draw Terrain Cross-sections
MOUS_ICO Menu: Road > Draw Cross-sections > Draw Terrain Cross-sections…

The dialog Select Horizontal Alignment will pop up.

Step 1 - Source Line, Calculation Settings, and Subsurface Information:

• Use the button Select to select the source alignment from the active terrain model
• Use the button Browse to select the ASCII file of the source alignment
• Use the button Pick to select the source line from the current drawing

Define how to calculate the terrain profile

• Calculation Interval: Define the interval for cross-section along the source line
• Calculation width: Define the extent (on both sides left/right) across the source line, for which the terrain data is to be fetched for terrain points. Thus obtained terrain points will be interpolated for terrain elevation at each cross-section. Further details - refer to Draw Terrain Cross-sections
• Terrain Calculation: Select if terrain surface should present all priorities together, or only the compound/resulting terrain surface based on the current priorities.
• Specify the materials for the top surface and subsurface layers. This information will be used by the drawing styles to draw materials in specific layers.

Click the button Next to define the presentation settings and the additional features that are to be included in the cross-sections. The dialog Draw Cross-section will pop up.

Step 2 - Presentation Settings and Additional Features

The active Quadri model, start chainage, and end chainage of the source line will be displayed at Quadri Model Info. To change the Quadri model, exit the function and run the function Select design task.

• Cross-section Selection:
  • Define the first and last chainage, between which cross-sections are to be drawn.
• Drawing Settings:
  • Define the insertion point of the first cross-section. Use the ellipse button to pick the insertion point from the current drawing
  • Section width: Cross-section width that is to be presented
  • Vertical spacing: Spacing between adjacent cross-sections in the drawing
  • Vertical exaggeration: Ratio of horizontal scale to the vertical scale
• Additional Drawing Objects:
  • Mark the check box of the respective option to include it in the cross-sections
  • Other alignments: Includes the other alignments available in the active terrain model
  • Wireframes: Includes the other wireframes that are available in the active terrain model
  • Existing objects: Include the existing objects available in the active terrain model
• Drawing style setting:
  • Select the desired cross-section setup from the list of pre-defined national standards for cross-sections
• Preview of the cross-section with the active drawing style is displayed at Cross-section Preview
• Execute the function with the button Draw
