Draw Cross-Section from Quadri

The function generates the cross-section terrain profile and draws it to AutoCAD drawing. The function draws terrain surfaces, soil layers, saved road lines, and surfaces available from all the active groups shown. The cross-section terrain profiles are generated and drawn at a desired interval.

Run the function from:

Ribbon: Novapoint > Terrain Information > Draw Cross Section from Quadri

The dialog 'Select Horizontal Alignment' will pop up.

Step-1: Horizontal Alignment

1. Select the baseline using the buttons 'Select', 'Browse', or 'Pick' - the baseline can be:

   • an alignment/object from the terrain model - use 'Select'

   • an ASCII file with the alignment data (*.TIT, *.LIN, *.DAT, *.INH, and *.LI) - use 'Browse'

   • a line/polyline/arc or alignment from the current drawing - use 'Pick'

2. Define the interval for the longitudinal profile at 'Calculation interval (m)'

3. Define interval for the longitudinal profile at 'Calculation width (m)'

4. Define your 'SubSurface Information' and choose the wanted 'Material' for all your 'Levels'

5. Click 'Next' to open the dialog 'Draw Cross Section' and define the output parameters

Note: The first point of the CAD entity will be the start point for calculations and presentation in case the baseline is a CAD entity.

Step-2: Output Parameters

The active Terrain model and the baseline information can be viewed at the top of this dialog.

Cross-section selection

Keep the 'First chainage' and 'Last chainage' of your line, if you want the whole project to be written out.

Drawing settings

'Insertion point' to place the cross-sections in the AutoCAD drawing. The default is 0,0 or you can pick the wanted point in the drawing. Then the dialog will pop up again and show the coordinates X and Y.

'Section width' is the total of 'Left width' and 'Right width' for the cross-section; you can choose differently for the left and right sides.

'Vertical spacing' gives space between the cross-sections, and the scale in the AutoCAD drawing gives the 'Vertical exaggeration'.

Additional Drawing Objects

If you want to 'Draw other alignments', 'Draw wireframes' or 'Existing objects' choose them here.

The option Drawing style setting you choose which predefined standard you want to use.

• Use the button 'Back' if you want to change the 'Input Parameters'.

• Or execute the function with 'Draw'.

Note: The Longitudinal profile will be inserted on predefined layers

The grips are the terrain heights. Cross-sections at every interval will be having the elevation of the alignment, chainage of the station, and identity of the alignment selected.
