Cross-sections

Run the function from the following locations:

MOUS_ICO Novapoint Road task > Design > Cross-sections
MOUS_ICO Road Modeler > View > Cross-sections…

The dialog box Cross-section Viewer will start.

The dialog box has three main areas;

Use this function to:

  • View and analyze the cross-sections (road and terrain cross-sections) of a road model
  • Access editing functions for the road model elements on the active or external models from the graphic area by clicking on it and activate the shortcut menu

The cross-section in the Cross-section Viewer will be updated automatically when the button Apply in the above mentioned dialogs is evoked.

The result objects of the road model will be deleted when using Apply as only one cross section is calculated. To get the result back calculate the whole road model through Preview, Finish or Refresh all chainage.

Having the Cross-section Viewer and a 3D-view in Novapoint Base active, makes for a powerful tool when optimizing the alignment (horizontal and/or vertical) and surface descriptions.

Together with showing the calculated cross-sections from the active road model the Cross-section Viewer is also able to display the following elements (if defined):

  1. Other alignments encountered within the search width

All the surfaces is displayed according to the Colour and Linetype Setup in the Toolbar.

When selecting one of the road model surfaces in the Cross-section Viewer it will blink steadily. Data from the surface will be displayed in the Properties Area together with key information from the general cross-section.

View the cross-sections by:

  • using the scroll-bar on the right side of the dialog enables to browse through the cross-sections
  • using the arrow button at the field Chainage of the dialog
  • entering the chainage value in the field Chainage
  • using the arrows keys or page up/page down keys on the keyboard

The size of the window can be adjusted manually or be maximized.

  • The last sizing is automatically displayed every time the dialog is activated.

Toolbar

The Toolbar consists of a few handy tools to operate the Cross-section Viewer.

Refresh all chainage

Use this function to recalculate all chainages

Refresh current chainage

Use this function to recalculate only the active cross-section in the viewer

  • This icon performs the same operation as that of the Apply button on the dialogs
  • The result objects for the road model stored in the Quadrimodel is deleted as the data is now updated

This option is an effective tool when repeatedly editing only one road cross-section. Scrolling through the road model will now be slow as each chainage is recalculated.

Toggles layers on off

Use this function to toggle layers on and off in the Cross-section Viewer:

  • Current Road - pavement, sub-surface layers and boundary lines
  • Terrain surface
  • Other Elements (wireframes, alignments, objects and external models
  • Information
  • Illustration Objects

The viewer will be updated dynamically in relation to layer selection.

Step length

Use this function to toggle what calculated cross-sections to view. By default, the quantity calculated chainages will be shown in the viewer

This can be modified by selecting Walk along these chainage and:

  • With interval as given for the cross-section calculation
  • Intermediate chainage (defined in Design > Settings > Chainage)
  • Chainage at surface break points (for every chainage with change in the road surface description or alignment elements)

Toggles the ruler on/off

Use this function to turn the horizontal and vertical rulers on/off.

There is an option to display the vertical ruler relative to reference alignment elevation or absolute elevations by pressing the icon between the horizontal and vertical rulers.

Toggles the grid on/off

Use this function to turn the horizontal and vertical grid lines in the graphical area of the viewer on/off. The grid size varies on zoom level.

Toggles properties on/off

Use this function to turn the Properties Area on/off in the bottom part of the viewer.

Measure distances

Use this function to measure diagonal, horizontal, vertical distances, and gradient

  • Pick the first point and move the cursor to the second point (don't pick the second point)
  • Activate the AutoSnap to points to get an accurate measure

Locate point in plan coordinate

Use this function to obtain the global coordinates in XYZ for any point in the cross-section.

AutoSnap to points

Use this function to activate different snap modes.

  • Snap to Endpoints (snaps to a surface endpoint)
  • Snap to Midpoints (snaps to a surface midpoint)
  • Snap to elevation symbol (snaps to an alignments vertical elevation)

Paning and zooming

Use these functions for various paning and zooming alternatives.

  • Pan
  • Zoom (press anywhere on the graphical view and move the cursor to zoom in and out
  • Zoom all (zooms to show the full cross-section with all available terrain and elements)
  • Zoom window (zooms to a defined rectangle)
  • Zoom road (zooms to show the calculated road model)

Colour and Linetype Setup

Use this dialog to setup the colours and linetypes for the dialogs graphical area (background, road model surfaces, grid, terrain and other elements.

Be careful not to select a background color for the viewer that will mask other elements with the same colour.

Properties Area

At the bottom of the Cross-section Viewer is the Properties Area showing data connected to the cross-section in the graphical area depending on what surfaces that are selected.

The Properties Area can be switched On/Off with the icon from the Toolbar, or by double click on the top border of the properties area.

When hovering over the different data in the Properties Area with the mouse a description of the field is displayed.

The Properties Area contains the following information:

  1. Chainage: Displays the cross-section chainage.
    - Enter the desired chainage number to view that cross-section.
    - If the desired cross-section is not previously calculated, this is done before it is displayed.
    - Any desired cross-section can easily be calculated with this function by entering the chainage value. The cross-section is not added to the road model, but only generated for viewing.
    - When a full cross-section calculation is performed these profiles will disappear.
  2. Subgrade type: This field displays the Subgrade Type of the active cross-section derived from the Soil/Rock usage in Pavement.
  3. Level of vertical alignment: The vertical elevation of the Reference Alignment in this cross-section.
  4. Gradient of vertical alignment: Gradient of vertical alignment.
  5. Horizontal position of pointer: Horizontal distance of the cursor pointer according to the horizontal ruler.
  6. Vertical position of pointer: Vertical distance of the cursor pointer according to the vertical ruler.
  7. Additional scarifying (the slider): Toggle surfaces to the left or right within the selected Surface group.
    - Useful if there are surfaces with small widths in the cross-section.
  8. Name of selected object: Name of the active surface.
  9. Surface group/type: There are different surface groups/types available in the road model. Select the desired surface from the pull down menu.
  10. Width: Width of the horizontal projection of the active surface.
  11. Slope: Cross slope of active surface in meter/meter
  12. Level: The elevation on the outer edge of the active surface.
  13. Horizontal distance: The horizontal distance from the alignment to the outer edge of the active surface.
  14. Vertical distance: The vertical distance from the alignment to the outer edge or the active surface.
