Introduction

The Vertical Grading Editor is the central design feature of the software.  It provides for the full vertical grading (profile) design and cross section generation of multiple string types (roads, profiles, curb returns, cul-de-sacs, knuckles, etc).

The Vertical Grading Editor is accessible:

Main Features and Benefits

This is an interactive and interconnected vertical grading (profile) and cross section design environment with the following features and benefits:

Marker/Tracker Display in the Drawing

The display of the 'tracker' that shows the relative location of the marker in the drawing 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 VGEMarker.dwg. 

Interface

The Vertical Grading Editor interface includes the following components:

  1. Ribbon Area (Top)
    • Users can start commands from here.  The ribbon is split into different panels covering different aspects of design, display, analysis and output.  Contextual ribbons will display when a PI is selected or group PI edits are required.
  2. Graphical Display Area
    • Displays the existing and design elevations, both graphically and textually.  Review longitudinal grades and vertical curve lengths. 
    • Select PI to edit and make selections for PI changes once a Ribbon command has been started
    • Zoom (roll middle mouse button), pan (hold down middle mouse button) and zoom extents (double click middle mouse button)
    • Right clicking will open the  Cross Section Viewer and lock onto the nearest station to the mouse position at the time of right clicking.  This cross section viewer window will automatically update the station following a right click by the user in the graphical display area.
    • Left clicking on a PI in the drawing will display a dynamic ribbon panel to enable direct PI editing

      Details are provided below for this contextual ribbon state
  3. Information Display Area (Bottom)
    • Save VGE
    • Close without saving edits
    • Minimise/Maximise ribbon
    • Enable a Grid Display
    • Change the tracker from a mouse to crosshairs
    • Describes any command currrently in progress
    • Details the design information of the nearest PI to the mouse pointer location
    • Details the exact elevation and distance of the mouse pointer location.
    • Includes zoom and pan commands:
      • Zoom in
      • Zoom out
      • Zoom window
      • Zoom extents
      • Pan

Marker/Tracker Display in the Drawing

The display of the 'tracker' that shows the relative location of the marker in the drawing 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 VGEMarker.dwg. 

Grid Lines and Crosshairs

The display of grid lines and crosshairs can be turned on/off for the Vertical Grading Editor Window, and can be set to defaults via the Settings form (see below)

Cross Section Window

Upon right click, one cross section window will open and match to the position of the mouse at the time of right clicking.  Also, right clicking will automatically update this cross section window to adopt the nearest station to the mouse.  More cross section windows can be opened using two methods:

  1. Use the Open Cross Section Window button on the Home Tab
  2. Hold down [shift]+[right click] the mouse to open additional cross section windows

The cross section window provides direct cross section edit capabilities - see the Cross Section Viewer help for more information.

Model Creation Behaviour - 'Mesh Refinement'

Whilst editing in the Vertical Grading Editor, rebuilds of the surfaces will exclude Mesh Refinement (additional sampling through vertical curves).  This improves surface rebuild performance during editing.

When the Vertical Grading Editor Window is closed, the models will be rebuilt with Mesh Refinement applied.

If it is required to review the surface with mesh refinement when the Vertical Grading Editor is open, the model/s should be rebuilt using commands from the ribbon/toolspace or by running the command Model tab > Update Model.

Civil 3D Interactions

All vertical grading edits made in the Vertical Grading Editor can be passed back to the Civil 3D profile by running the Create Profiles command. 

Profiles that are generated using the Create Profiles can be edited in AutoCAD Civil 3D and the changes to the profiles can update the CSD Vertical Grading designs by running the Update Profiles command.

 

Details

The Vertical Grading Editor provides multiple Vertical Grading Design windows to edit the design profile views (profiles) of any number of Roads, Strings/Profiles, Curb Returns, Cul-de-sacs, Knuckles , Roundabouts simultaneously, whilst still maintaining interactivity between dependent components (eg: Side road vertical gradings match the cross section of the Main Road roadway at the intersections. Curb returns, Cul-de-sacs and Knuckles automatically match the edge of the road for the Main Road and Side Road at their start and end).

    Editing Panel  
     Automate Vertical Design This command provides access to a variety of calculation methods to generate a vertical grading for the current CSD Object open in the Vertical Grading Editor.

As VC Methods are applied they are added to the list.  The Vertical Grading controls are applied in order, from the top to bottom of the list.  The list can be reordered using the up/down arrows on the right.

File Menu Command buttons enable the user to select the method desired for setting the vertical grading
  Import CSD Vertical Design The Import VC command allows the designer to import a vertical grading design to file. The file structure matches what is created when Export VC is used. It would be usual to use Export VC to create an exported vertical curve file, edit in a program such as Notedpad, then use this command to import the changed vertical design back in.

  Export CSD Vertical Design The Export VC command allows the designer to export a vertical grading design to file. The file exported can be opened in a program such as Notepad to be edited. A window will display to select a save location and a name for the export file.
  Calculate centreline elevations using the following methods
  Reference Surface This method allows the designer to create PI's at sampled sections (over a specified station range) and match the elevations of these PI's to a specified surface model. If the Use Fitting option is checked, the software will filter out the calculated PI's and smooth the design by inserting vertical curves. This option can also be used to add a elevation adjustment. For example, the designer might opt to match all elevations to an existing surface and then raise this design by 50mm.

Start Station Apply from start station
End Station Apply to end station
Surface Pick list for surface to extract elevations from
Use Fitting Toggle this on to 'smooth' out the design.  The software will apply a cut and fill factor to create an envelope of elevations, then fit PI's so the tangents do not pass outside the envelope.
Cut Factor Allows for this amount of cut against the sampled surface before inserting a new PI
Fill Factor Allows for this amount of fill against the sampled surface before inserting a new PI
Min. Vertical Curve Length Sets the minimum desired vertical curve length
Sag K Factor Vertical curve lengths will be set from this K factor in sag situations, where possible
Crest K Factor Vertical curve lengths will be set from this K factor in crest situations, where possible
Elevation Adjustment Lifts/lowers the outputted fitted vertical grading
Active Untick to disable the entry
OK Apply and exit.
Cancel Exit the form without changing any data.
  Reference Point This method will create PI's at each sampled section based on selecting a Reference Point and slope projection to the current Vertical Grading.  This is the most versatile option for establishing elevations based on existing or design data.

There are three Steps in the process:

  1. Define the Reference Point: The Reference Point is used as a reference for elevations and offsets to the current Vertical Grading.  Designers select to extract elevations from either the Design surface or the Sampled Surface, then select the method to determine the offsets.  Offset and elevations provide the Reference Point
  2. Project Slopes from the Reference Point to the Current String: Designers are able to have the software calculate slopes from the Reference Point to the current Vertical Grading based on a variety of different methods
  3. Apply Slope and Elevation Adjustments: Users can elect to add a height adjustment to the calculated elevations and/or use the reverse of the calculated slopes obtained from Step 2

The calculations of the Reference Point and Projected Slopes is made at EACH sampled section and an PI elevation established (with an optional height adjustment).

The image on the right side of the form adjusts to highlight relevant inputs based on the mouse hover location on the form.

Details of the Form and the steps are as follows:

 

Step 1 - Define the Reference Point
Surfaces Obtain Elevations for Reference Point and Slope from - options are to use the Sampled Surface or Design
  From Sampled Surface Toggle - Elevations are read from the Sampled surface in calculating the reference point and slopes (pending slope option used).  Form display is as follows:

  From Design Surface Toggle - Elevations are read from either a design String or Code in calculating the reference point and slopes (pending slope option used).  Form display is as follows:

Reference Point Position Sets the offset at which to calculate the Reference Point - elevation is then calculated from the sampled or design surface, based on selected toggle option
   Reference String Use the pick list to select the Reference String.  Behaviour is as follows:
- From Sampled Surfaces selected.  This sets the new PI locations (by station/station) on the current string CL.  It would be usual to select the current design C.L. string.
- Drom Design String selected.  This sets the design surface from which to extract elevations (as well as setting the new PI locations (by station/station) ont the current string C.L.).
  From Alignment Select an alignment for the offset location of the Reference Point.
Only available if From Sampled Surfaces is selected.
  From Design Code Select a Code for from the Reference String to use for the offset location of the Reference Point.
Only available if From Design String is selected.
  Offset Reference Point User can 'shuffle' the Reference Point offset using this option - type in the required value (-ve for Left and +ve for Right)
  Maximum Offset Set a maximum offset to search for the Reference Point, measured from the alignment/string centreline

 

Step 2 - Project Slopes from the Reference Point to the Current String
Slope Selection Toggles to select the method of calculating the slope projections from the Reference Point.  The form display provides different inputs depending on the toggle option selected.
   Constant Allows for the specification of a single crossfall to apply from the Reference Point to obtain elevations.

The expected file format is as follows (editable in a text editor) and matches the format of the file used in the Export VC command.  However, this command will allow import of ONLY a file with extension .txt.

<Station>,<Elevation>,<Vertical Curve Length> separated by an [Enter] per point.  Save the file with extension .txt.

Example file:
0, 110
60, 95,80
120, 93

       Fit Vertical Curve/s Between PI's This command is used to insert a either a single vertical curve or a vertical curve pair based on the incoming grade to the first PI and the outgoing grade from the second PI.  The process is the same as is used for designing Curb Returns and is as follows:
  • The intersection point of the two tangents is checked to see if it falls in the middle half of the distance between the two PVIs.
  • If it does, then a new PI is created at that point with vertical curve length equal to the half distance.

  • If it doesn't, then the two PVIs are deleted and 4 new PVIs are created.  Two at the quarter distance between the two original PVIs with vertical curve lengths of half the distance and two at the ends of the new vertical curves.

  Design Constraints Ribbon Tab
    Design Constraints are a powerful design aid.  They provide the ability to show additional elevation information describing elevations and projections from other features (eg: left edge of road, left batter/daylight, a different string, another surface).  Users can snap design PI's onto these contraint profiles and visually compare them to the current design string elevations.

Find more information about the full range of Design Constraints via the Design Data form help information. Summary information will be provided below.
    Manage Panel  
    Type Select the type of Design Constraint from the picklist:
  • Project Design (Alignment)
    • User picks a design string and an alignment.  Using the horizontal positioning from the alignment, elevations are adopted from the design string surface.  Users can then apply a slope to project elevations from the reference point to the current string.  Slope projections are made perpendicular to the reference alignment.
    Project Design (Code)
    • User picks a design string and a code from the design string.  This sets the reference point elevations.  Users can then apply a slope to project elevations from the reference point to the current string.  Slope projections are made perpendicular to the reference string/code.
  • Project Surface (Alignment)
    • User picks a surface and an alignment.  This sets the reference point elevations.  Users can then apply a slope to project elevations from the reference point to the current string.  Slope projections are made perpendicular to the reference string/code.
  • Show String
    • User picks a string to display and an elevation adjustment.  The elevations from the string are projected directly onto the current string.
  • Show Surface (Alignment)
    • User picks a surface and an alignment.  This sets the reference point elevations and these are projected directly onto the current string.
  • Show Surface (Code)
    • User picks a surface, a design string and then a code.  This sets the reference point elevations and these are projected directly onto the current string.

Inputs are provided relevant to the type of constraint being applied
