Purpose

To write a section file to enable the drawing of the design cross sections and provide a comprehensive report / 3D schedule file.

 

Operation

Pick the Horizontal Alignment. If a Road name has been assigned with menu item Design, Horizontal, Extract geometry and the previous menu item Strings, Draw has been run then the .vtg and .stg files used appear as defaults in the Road details dialogue – if this is not the case select the vertical geometry file (the Master String now exists) and select the string file. Select output options from the dialogue :-

Section file

"On" to write cross section file.

 

Draw Polylines

Only required to show section plan locations.

 

Report file    

"On" to write .kdr report file – note that the data is also presented in the text screen.

 

Include Embanks.    

Only needed if drawing as 3D Polylines and plan extents are to include embankments.

 

Layer      

To draw cross section plan locations on.

 

Road Name    

As set by Design, Horizontal, Extract Geometry.

 

Interval      

Enter the interval for the cross sections.

 

Chainage at Start of Polyline    

Defaults to the chainage at start of Horizontal Alignment.    

   

Start / End Chainage    

Set range for cross sections to be calculated over.

 

Include/Exclude Strings...  

Select strings to be included – default is all.

 

Use Embankment

"On" to calculate embankments from each end of every cross section. Click Settings... to confirm that cut and fill gradients are correct – this setting is independent of Ground Modelling, Embankments. You will be prompted to select the model after clicking Start when all parameters have been set.

 

Special Chainages    

Enable cross sections to be located at additional chainages added to the list by hand or previously saved into a .lsc file by menu item Design, Horizontal, Extract geometry.

 

In typical use the main output is the design cross section file. Use menu item Sections, Superimpose, Cross Sections to add these onto existing site cross sections that have probably been created from the site model.

 

The .kdr design report file looks like this :-
