Open Cross Section

Icon:      

Introduction

Civil Site Design supports the opening of multiple cross section windows for any string.

This command allows the designer to open a new cross section window for any selected CSD object.  This window will display the cross section design at the user nominated chainage for the selected CSD object.  After starting the command, the designer needs to select the CSD object (eg: Road) and the chainage to display.

The Cross Section Window is also accessible from:

Interface

The cross section includes the following components:

  1. Ribbon Area (Top)
    • Navigate chainage, access vertical and cross section design forms and manage display
    • Chainage selection.  This is controlled by the navigation buttons at the top of the form:
    • hover in the Ribbon Area and roll the mouse buttton up/down to automatically increment through the chainages.
  2. Graphical Display Area
    • Displays the existing and design sections, both graphically and textually. 
    • Zoom (roll middle mouse button) and pan (hold down middle mouse button)
    • Right click near a code to enable Direct Section Editing:



      Direct Section Editing       allows users to edit code positions horizontally and/or vertically, edit batter/daylight conditions or open the Section Design Data form for the current cross section.

      Note: All actions available in the Direct Section Editor shortcut menu are reflected in the Design Data form.  Changes to cross sections in the Section Design Data form are changing entries in the Design Data form.
  3. Information Display Area (Bottom)
    • Minimise/Maximise Ribbon
    • Zoom extents
    • Zoom in
    • Zoom out
    • Zoom to section in the drawing
    • Details the nearest code
    • Details the exact elevation and distance of the mouse pointer location.
    • Enable a Grid Display
    • Change the tracker from a mouse to crosshairs

Display Controls

Users are able to configure the information displayed in the Cross Section Window, including the inclusion of objects in the view such as other Strings/Profiles, Alignments, CSD Pipes and selected AutoCAD objects.  Whilst this can typically be configured on each cross section window displayed, defaults can also be set for cross section windows when they are opened via the following CSD commands:

Marker Display in the Drawing

The active cross section is highlighted with a marker in the drawing.  This marker is managed via a block in the Civil Site Design Settings (CSD Settings) folder.  Users are able to replace this drawing block as desired.  The CSD Settings folder can be opened in Windows Explorer via the Open Settings Folder command in the General menu/ribbon.  The block is named XSECTACTIVE.dwg. 

As the mouse if moved across a cross section window, a line will track the mouse location, displaying perpendicular to the section in the drawing.

About Direct Section Editing and the Section Design Data Form

It is often helpful to be able to do two things when viewing a particular cross section in the Cross Section Window:

  1. Be able to force change to the cross section Code/s, affecting that cross section chainage (and potentially a range of chainages).  The change may be to delete a Code, insert a new Code, change the width/slope of a Code, change a Code offset to match an alignment, or set a Code to adopt the offset and elevation of another String.
  2. See the applied Template, Variations and Batter overrides applied at a particular cross section

Direct Section Editing delivers on point number 1 - users can right click to the nearest Code on the cross section window and execute a Variation related to that Code, or apply a Batter Override.  A form will display following right click and an action selection, for the user to confirm what change is required and over what chainage range.

The Section Design Data form delivers on point number 2 - when opened, it will display the template applied, all Variations and Batter Overrides that apply at that chainage.  Changing the section being viewed (by looking at a different chainage) will update the details automatically in the Section Design Data form.  Users can see all changes applied to a cross section (template, variations and batter slope overrides) at any chainage.

In the above cases, the software is directly adding/editing entries in the Design Data form.  The Design Data form stores all changes applied via the cross section window.
