Road Display Settings



This Tech Tip explains the various options available in the Roads Display Settings.


There are 2 ways to access display settings:

Via the menu, Settings Menu › Display Settings or via the toolbar

 
 


 

Display settings dialog
 


The following options are available:
Display road plan Check this option to enable display of roads.
Vis. column Set the visible status for each of the available roads. Enter either Yes or No in the desired cell or right-click the cell to toggle the current setting.
CAD Layer column Enter the name of the CAD layer on which items for this road should be drawn when plotting a plan. Two variables are available, {NUMBER} and {TYPE}, which translate to the road number and item type respectively. Right click the relevant cell to select from a menu.
Visible Button Click this button to set all the cells in the Vis column to Yes.
Hidden Button Click this button to set all the cells in the Vis column to No.
Current road settings - Start chg and Stop chg Enter the first and last chainages of the range of the horizontal alignment to be displayed. Applicable only to the currently highlighted road.
Current road settings - Bank layer Select the layer that contains the cross sections for which banks should be drawn.
Current road settings - Plot road names Check this option to display the road name, assigned to the road in the Select Roads File dialog, on the road layout plan.
Current road settings - Interval Enter the road name interval in meters. This value is the repeat distance for the road name text.
Current road settings- Pen Specify the pen colour for the road name text.
Current road settings- Text size Enter the text size for the road name text.



 

Chainage interval Enter the interval between successive chainage indicators.
Chainage Label Interval Enter the interval between successive chainage labels
Chainage kilometre separator Enter the kilometre separator. If you enter "km " chainage 1250 will be written as "1km 250" on the road plan.
Decimal places Enter the number of decimals to be displayed in the chainage labels.
Offset for start of indicator Enter the offset from the centreline at which the indicator line should start drawing. Offsets to the left of the centreline should be entered as a negative value.
Offset for end of indicator Enter the offset from the centreline at which the indicator line should stop drawing. Offsets to the left of the centreline should be entered as a negative value.
Label pen Button Click this button to select the colour in which to display the labels.
Size Enter the size of the labels in points.
Label Offset Enter the offset from the centerline where the labels should be plotted.
Label Position Enter the position of the chainage label relative to the chainage coordinate on the center line. This option can be set to: Above, Below, Left or Right.
Label Skew Sections Check this option to label all the skew sections with the change label and skew angle. If this option is checked then skew sections will always be labeled regardless of the Chainage Interval.
Box out text Check this option to box out the label text.
Labels parallel to road Check this option to have the labels placed parallel to the centerline instead of at right-angles.
Label BCC and ECC Check this option to have the beginning and ending of curves labelled in addition to the regular chainages.
Chainages for BC and EC Check this option to display the chainages for the BCC, ECC BTC and ETC points.
Plot column Select whether the particular line should be plotted or not. Enter either Yes or No in the cell or right-click the cell to toggle the current setting.
Pen column Enter a pen number or right-click the cell to display the colour dialog in order to specify a pen with which to plot the line.
LT column Enter the number of the linetype in which to display the line.
Smth column Select whether the line should be smoothed or not. Enter either Yes or No in the cell or right-click the cell to toggle the current setting.
Offset column Enter either the offset, point location code or ID of the cross section point that should be used for plotting this line.
Pos column Specify whether the entered value in the Offset column is a point location code, point ID or an offset. Right-click the cell to alter the current setting.
Layer column Right-click the cell and select the layer from which the cross section data should be extracted.
Change all roads to these settings Press this button to copy the visible settings to all the existing roads.

 

 

You can substitute the text when for BC's and EC's on a plan to change from the standard BTC, BC, EC and ETC to any text you like. In order to change the text used you must make an entry in the project file (the .cdp file) as follows:
 

  [RoadLabel]
  BTC=w
  BC=x
  EC=y
  ETC=z

 
where w, x, y and z are the text you want substituted. The program will default to the original values for any entry not found. Note that due to the placement in the .cdp file this is a per-job setting and that you are limited to a substitution string of 9 characters or less.

Changing the display settings to show different information on screen.

 

 


 

 

Always plot at Default rotation Check this option to keep the rotation of the Curve and PI details text at Zero degrees when you generate a plan plot, regardless of the rotation of the plot.
Show Curve Details Check this to display Horizontal curve details onto the Design Center window.
Show PI Details Check this to display the PI details onto the Design Center window.
Pen Pen colour for the curves or PI box
Box out text Check this option to have a box filled in the current drawing background colour placed behind the details text. This is a useful option if you wish to blank out portions of the underlying data in order to highlight the text.
Size Enter the text size for the relative details box in points.
Offset from Road CL (Curve Details) Enter the distance in meters from the crown of the horizontal curve towards the curve center point where the curve details have to be plotted.
Offset from Road CL (PI Details) Enter the distance in meters from the PI position away from the curve center point where the PI details have to be plotted.
PI Indicator Check this option to indicate the PI position.
Indicator Size Enter the size of one of the two lines that form the PI Indicator, in meters.
Text Enter the text to be written into the Curves, or PI details boxes. A number of variables are available. Right click the relevant cell to select from a menu.

 

 

The Text variables are:

 

{RADIUS} Horizontal curve radius
{TR_IN} Transition length in
{TR_OUT} Transition length in
{BACK_DIR} Back direction
{FRONT_DIR} Front direction
{TAN_IN} Tangent length in.
{TAN_OUT} Tangent length out
{I} Intersection angle
{PI} PI name as specified in the Horizontal Alighment.
{PI_Y} PI Y-coordinate
{PI_X} PI X-coordinate
{CC_Y} Horizontal curve center point Y-coordinate
{CC_X} Horizontal curve center point X-coordinate
{BCC_Y} Begining of circular curve Y-coordinate
{BCC_X} Begining of circular curve X-coordinate
{ECC_Y} End of circular curve Y-coordinate
{ECC.X} End of circular curve X-coordinate
