VGE - Vertical Grading Editor

---

Introduction

TheVertical Grading Editor is the central design feature of Advanced Road Design .  It provides for the full vertical grading (profile) design and cross section generation of multiple roads, strings, kerb returns, cul-de-sacs, knuckles, and other ARD object types.

The Vertical Grading Editor is accessible:

• At the time of creating
  • Roads
  • Strings
  • Kerb Returns
  • Cul-de-sacs
  • Knuckles
• For editing an existing ARD Object (Road, String, Kerb Return, Cul-de-sac, Knuckle, Roundabout or Off Ramp)

Civil 3D Interactions

All profile adjustments made in the Vertical Grading Editor can be passed back to the Civil 3D profile by running the Create/Update Civil 3D Profiles command.

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

Main Features and Benefits

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

• a full set of vertical design tools to graphically and/or numerically create/edit IP's (PVI's) and vertical (parabolic) curves
• a range of tools to automatically create IP's and vertical curves based on existing or other design data.
• the ability to open multiple Cross Section Windows from the vertical grading editor display
• direct access to the Create/Edit Templates form to facilitate creation/editing of cross section templates
• the inclusion of a 'model space' tracker in the drawing window to co-ordinate the mouse position in the Vertical Grading Editor with the position in the model.  The marker will automatically resize as you zoom in the drawing window.
• multiple Vertical Grading Editor windows can be opened and edited simultaneously, so designers can see the effect of changing a Vertical Grading on any other interconnected ARD Object (such as side/crossing roads, kerb returns and cul-de-sacs)
• the Vertical Grading Editor window is modeless - designers can simultaneously execute commands and work in the AutoCAD Civil 3D environment
• the Vertical Grading Editor window is fully re-scalable - the vertical grading (profile) exaggeration and width will automatically adjust to accommodate the space of the window
• crossing Road strings are shown on the vertical grading editor window and includes the name of the crossing road string

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 Advanced Road Design Settings (ARD Settings) folder.  Users are able to replace this drawing block as desired.  The ARD 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.

Details

The Vertical Grading Editor provides multiple Vertical Grading Design windows to edit the design long sections (profiles) of any number of Roads, Strings/Profiles, Kerb Returns, Cul-de-sacs, Knuckles , Roundabouts and Off Ramps 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. Kerb 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).

Upon opening the Vertical Grading Editor the following form is displayed:

Details of the form are as follows:
	Display Set Parameters form	The display of profile grades, high/low points, level information and text size can be controlled by the designer.  This is achieved by clicking on the Display Set Parameters button. Note: These controls are mirrored in the Active Drawing Settings - Vertical Grading tab. The controls of the form are graphically outlined below: Design Aids These settings assist the designer in achieving design compliance   Crest K Value Type in the required K value for creating crest curves.  At the time of Adding IP's in the Vertical Grading Editor the software will use the specified K factor to indicate a suitable vertical curve length to achieve the K factor required for crest curves.   Sag K Value Type in the required K value for creating sag curves.  At the time of Adding IP's in the Vertical Grading Editor the software will use the specified K factor to indicate a suitable vertical curve length to achieve the K factor required for sag curves.   Maximum Grade for Warning (%) Type in a desirable maximum grade (%).  If the incoming or outgoing grade from a IP exceeds the maximum the grade indicator will turn Red.  Otherwise the grade indicator is Green.   Minimum Grade for Warning (%) Type in a desirable minimum grade (%).  If the incoming or outgoing grade from a IP is less than the minimum the grade indicator will turn Red.  Otherwise the grade indicator is Green. Items to Display Set what textual and other graphical information is displayed in the Vertical Grading Editor Design Window.  Some of the relationships are shown, above   Show Chainages Tick on to show the Chainage values in the Vertical Grading Editor window.  This will show the alignment chainages by default - if another road has been used for chainages (Use Other Road Chainages command), the other road chainages will display here.   Show Design Levels Tick on to show the Design Levels (Elevations) of the long section in the Vertical Grading Editor window   Show Level Differences Tick on to show the Level Difference between the Design Level of the vertical grading and the Sampled Surface in the Vertical Grading Editor window   Show Existing Levels Tick on to show the Existing (Sampled) Surface Levels in the Vertical Grading Editor window   Show High/Low Pt's Tick on to highlight the location of the high/low points in the Vertical Grading Editor window (small circle located along the design grading)   Show Grades Tick on to textually display the grades either side of the IP's and the Vertical Curve Lengths in the Vertical Grading Editor window   Show Volumes Tick on to display a summary of the bulk earthworks whilst editing using the Raise/Lower IP by Fixed Amount command   Show Envelopes Tick on to graphically display Design Constraints (created via the Design Data Form) as additional long sections (profiles) in the design window.  These are very helpful design aids to ensure grade and level controls to other features are met.  Any Design Constraints (Envelopes) and also be used for assigning levels (elevations) when creating IP's.   Show Align.

	Fit Vertical Curve/s Between IP'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 IP and the outgoing grade from the second IP.  The process is the same as is used for designing Kerb 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 IP 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. Note: This command will only work if the IPs left and right of the selected location do NOT have vertical curves on them.
	Compute VC from Existing Data	This command provides access to a variety of methods to generate a vertical grading for the current ARD 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. VC Methods Command buttons enable the user to select the method desired for setting the vertical grading   Match to Existing This method allows the designer to create IP's at sampled sections (over a specified chainage range) and match the elevations of these IP's to a specified surface model. If the Use Fitting option is checked, the software will filter out the calculated IP's and smooth the design by inserting vertical curves. This option can also be used to add a level adjustment. For example, the designer might opt to match all levels to an existing surface and then raise this design by 50mm. Start Chainage Apply from start chainage End Chainage Apply to end chainage Surface Pick list for surface to extract levels from Use Fitting Toggle this on to 'smooth' out the design Cut Factor Allows for this amount of cut against the sampled surface before inserting a new IP Fill Factor Allows for this amount of fill against the sampled surface before inserting a new IP Min.

Cancel Exit the form without changing any data.   Reference Line This method will create IP'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 levels based on existing or design data. There are three Steps in the process: Define the Reference Point: The Reference Point is used as a reference for levels and offsets to the current Vertical Grading.  Designers select to extract levels from either the Design surface or the Sampled Surface, then select the method to determine the offsets.  Offset and levels provide the Reference Point 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 Apply Slope and Level Adjustments: Users can elect to add a height adjustment to the calculated levels 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 IP level established (with an optional height adjustment). Details of the Form and the Steps are as follows: Step 1 - Define the Reference Point Obtain Levels for Reference Point and Slope from - options are to use the Sampled Surface or Design Use Sampled Toggle - Levels are read from the Sampled surface in calculating the reference point and slopes (pending slope option used).  Form display is as follows: Use Design Toggle - Levels 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: Obtain offset for Reference Point from - here the designer specifies both the Road to use and the Alignment (or Label, pending Surface option) for the software to read the offset from and calculate a level.  Options are Centreline Alignment Use the pick list to select the Road alignment - it is usual to select the current Road Use String for Reference Line Offset Use the pick list to select a String defining the Reference Point Use Design Code for Reference Line When Design Surface is toggled on, the user can ALTERNATELY specify a Design Code instead of a String to determine the Reference Point. Use the pick list to select the Road cross section Label (eg: LEB, REB, LINV, etc) to use for defining the Reference Point. Offset From Reference Line User can 'shuffle' the Reference Line offset using this option - type in the required value (-ve for Left and +ve for Right) Step 2 - Project Slopes from the Reference Point to the Current String Select the Slope Projection Method - 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 levels. Form display is as follows: User input is as follows: Constant Type in the % slope project required Single Point Calculates the Slope at a selected offset and uses the calculated slope to obtain levels. Form display is as follows: User input is as follows: Slope Point 1 - Obtain Offset/Slope from : Use the Toggle to select the required method Alignment Use the pick list to select an alignment to determine the offset location to calculate the slope Offset Type in a fixed offset from the Road C.L. Alignment.  Convention is -ve left of the C.L. and +ve right of the C.L.  2 Points Calculates the Slope between two selected offsets and uses the calculated slope between the two points to obtain levels. Form display is as follows: The average slope is calculated between the offset/level found for the two Slope Points and is then applied. User input is as follows: Slope Point 1 - Obtain Offset/Slope from : This records the first offset value and then sets the level based on the Sampled Surface or Design Surface.  Use the Toggle to select the required method Alignment Use the pick list to select an alignment to determine the offset location Offset Type in a fixed offset from the Road C.L. Alignment.  Convention is -ve left of the C.L. and +ve right of the C.L. Slope Point 2 - Obtain Offset from : This records the second offset value and then sets the level based on the Sampled Surface or Design Surface.  Use the Toggle to select the required method Alignment Use the pick list to select an alignment to determine the offset location Offset Type in a fixed offset from the Road C.L. Alignment.  Convention is -ve left of the C.L. and +ve right of the C.L. Use Table User is able to set crossfall values in a table - the software applies the selected crossfalls based on chainage and crossfall entries in the table.  Interpolation occurs between the crossfall entries in the table. Form display is as follows: User input is as follows: Table: inputs are as follows Chainage Type in a chainage Specified Crossfall % Type in a crossfall value Note: the software will interpolate crossfall values between the chainages in the table Step 3 - Apply Slope and Level Adjustments Height Adjustment Toggle ON if a height adjustment should be added to the calculated levels. Type in a value to raise/lower (+ raises the IP's) the calculated levels. Reverse Slope Toggle ON to reverse the calculated/defined slope values and apply this to determine the calculated levels. Start Chainage Apply from start chainage End Chainage Apply to end chainage OK Apply the inputs and exit the form Cancel Exit without applying changes Sort Sorts the chainage values in the table - only relevant when the Select the Slope Projection Method is set to Apply Slopes from a Table. Constraints Click on this option to create IPs at a constraint as defined in the design data form.  Form displays as follows: User input is as follows: Start Chainage Apply from start chainage End Chainage Apply to end chainage Constraint Choose a constraint that has been defined in the Design Constraints section of the Design Data form OK Apply the inputs and exit the form Cancel Exit without applying changes   Copy String This method allows the current vertical grading to be created using the vertical grading of an existing string. All the IP's (chainage and level data) on the existing string will be re-created in the current vertical grading. Copy from Select the String/Profile to copy the vertical design from Apply to Select the String/Profile that you copy the vertical grading data to Start Chainage Apply from start chainage End Chainage Apply to end chainage OK Apply and exit. Cancel Exit the form without changing any data.   Fit Parameters Although some methods, such as the Match to Existing method contain Fitting parameters, this method allows for an overall Fit/Smooth to be applied over a calculated vertical design. A calculated design might consist of a combination of multiple methods and these Fit Parameters can be added as the final method to be applied. Alternatively, this method can only be applied when the Fitting command is used. Start Chainage Apply from start chainage End Chainage Apply to end chainage Cut Factor Allows for this amount of cut against the sampled surface before inserting a new IP Fill Factor Allows for this amount of fill against the sampled surface before inserting a new IP 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 Level Adjustment Lifts/lowers the outputted fitted vertical grading Use with Other VC Methods This method will be applied at the point at which it is listed in the Vertical Grading controls list. This command will be used in conjunction with all other methods applied to create the vertical design. Use Only with Fitting Command This method will be applied only when the Fitting command is used. OK Apply and exit. Cancel Exit the form without deleting any data. From String Click on this option to copy another String/Profile, with the capacity to adjust the IP levels based on grade or elevation controls. This routine was originally envisaged for road reconstruction works, where it was desired to take the design for one side of the road and project it across to the other side.  The copied profile IP's and Vertical Curves are transferred to the current Vertical Grading. At least one other profile must be available in the drawing - normally these are created from the Create String/Profile command Form display is (be default) as follows: Under the heading Specify the Adjustment Method to Apply During String Copy select one of two calculation methods: Apply Crossfall Adjustments Use Level Difference The graphic and inputs will adjust depending on the option selected. User input is as follows: Apply Crossfall Adjustments : the original profile data is copied across, with the IP levels adjusted based on crossfalls from a selected profile to the current Vertical Grading Select String to Copy Use the pick list to select the profile to copy data from Select Road Alignment for CL Use the pick list to select a Road centreline Crossfall to CL Type in a crossfall to adjust levels of the IP's to the CL Crossfall to Current String Type in a crossfall from the CL to the current Vertical Grading Start Chainage Apply from start chainage End Chainage Apply to end chainage OK Apply and exit. Cancel Exit the form without changing any data. Use Level Difference : the original profile data is copied across, with the IP levels adjusted by a fixed height change Select String to Copy Use the pick list to select the profile to copy data from Select Road Alignment for CL Use the pick list to select a Road centreline Level Adjustment Type in a value to adjust the levels of the IP's copied to the current Vertical Grading Start Chainage Apply from start chainage End Chainage Apply to end chainage OK Apply the profile copy to the current Vertical Grading Cancel Exit without applying vertical grading changes  Import / Export VC 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 Microsoft Excel to be edited. It may be required to shift the chainage of IP's - Microsoft Excel can be used to increment chainages or elevations and the edited data can be re-imported using the Import VC command. From File The From File command allows the designer to import a file of vertical geometry points and create IP's and vertical curves from this data.  The file should be structured as follows: <Chainage>,<Elevation>, separated by an [Enter] per point.  Save the file with extension .txt. Example file: 0, 110 20, 95 30, 93 OK Apply and exit. Cancel Exit the form without deleting any data.
