Draw Longitudinal Profile from Quadri

The function generates the Longitudinal Terrain Profile from the database along the requested line and draws the same to the working AutoCAD drawing. The function draws terrain surfaces, soil layers, saved road lines, and surfaces available from all the active groups are shown.

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 an interval for the longitudinal profile at 'Calculation interval (m)'

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

4. Define an offset line on the left side at 'Terrain at Left Side, offset (m)'

5. Define an offset line on the right side at 'Terrain at Right Side, offset (m)'

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

7. Click 'Next' to open the dialog 'Draw Longitudinal Profile from Terrain Model' 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 on the top of this dialog.

Longitudinal profile settings

'Start chainage' is the start point for your longitudinal profile. 'Datum' is the option to place the longitudinal profile at the best position in the frame. 'Insertion point' to place the frame in the AutoCAD drawing. You pick the wanted point in the drawing and the dialog will pop up again and show the coordinates X and Y.

Frame settings

Uses the length of your line to 'Frame length'. The scale in the AutoCAD drawing gives the 'Frame height' and the 'Vertical exaggeration'.

Additional Drawing Objects

'Main Alignment' and 'Main Alignment info' is available if 'Select' or 'Browse' is the choice at Step 1.

If you want to show other 'Wireframes', 'Other alignments' or 'Existing objects' choose them.

If you like to see the terrain at bought sides of the terrain line, choose 'Terrain offset left' and 'Terrain offset right' with the values you selected at Step 1.

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.
