Purpose

To make a 2D Polyline representing a Horizontal Alignment more "road specific" with options to mark the geometry and write report files.

 

Operation

Select the 2D Polyline. The direction of the Polyline defines the direction of increase in chainage – to verify and reverse use menu item Polyline utilities, Reverse direction.

Marking

Road Name

Enter road name (max 8 characters).

 

Chainage at start of Polyline

Enter a value if this is not to be 0.000.

 

Annotation Offset

Distance from Polyline to chainage label.

 

Number of decimal places

For chainage markers.

 

Interval

Enter the chainage interval.

 

Layers

Set layers for chainage text and geometry markers.

 

Road Description

Enter description or comments (optional)

 

Nominal Scale

Fixes text height of chainage markers.

 

Set start chainage at <

Pick a location along the Polyline and it's chainage will be reported in a dialogue. To set a new chainage at this location enter the new value and the chainage for the start of the Polyline will be recalculated.

 

Special Chainages

Special chainages are in addition to the regular intervals and vertices. There are four different types :-

General

e.g. fence, line of trees or other ground feature that needs to be marked.

Road Centre-line

e.g to show where Road2 links in to Road1

Manholes SW

Used to locate manholes for menu item Translators, WinDes, WinDes to KTF Section.

Manholes FW

Used to locate manholes for menu item Translators, WinDes, WinDes to KTF Section.

Add... to type in chainage.

Pick < to pick the location.

Input   to read from existing .lsc file.

Clear removes all lines in the list. (Double click any line to remove it from the list).

 

Additional file and drawing options...

Write

.hzg files are mainly used for transition curves and do not need to be output here for typical use.

.lst file lists the geometry from the 2D Polyline and the

.lsc file lists all regular locations plus vertices.

.xml LandXML format file for exporting to other systems optionally including also vertical alignment

The above two files may be read into Word documents or added into the drawing with Design, Schedules and analysis.

 

Mark        

Regular chainages at the specified interval.

Elements to mark all vertices i.e.tangent points

IPs to mark intersection points.  

 

Chainage, element and IP marking

Chainage, element and IP marking

 

The .lst file lists the basic geometry :-

The .lsc file lists regular and special chainages plus manhole co-ordinates :-
