Export Corridor

Introduction

This commands exports/recreates the corridor from a Civil Site Design/Corridor EZ model.  All Strings and Codes in the Civil Site Design/Corridor EZ model will be used.  The command will:

• Create a list of all the strings and cross section codes used in the Civil Site Design/Corridor EZ model.

• Create Civil 3D profiles for each String

• Create assemblies and subassemblies to cater for changes in the cross sections of each String (managed via the Exchange Settings command)

• Create additional alignments and strings for road edges

• Create a Corridor for the selected Civil Site Design/Corridor EZ model:

  • Creating baselines for each design String

  • Adding regions and applying assemblies, based on the applied Variations and Template changes

  • Apply Target Mapping to road edges, curb returns and cul-de-sacs, as well as for some Variations (as per the Corridor Settings command).

  • Apply Parameter Overrides as required for subassembly widths and elevations to match the Civil Site Design/Corridor EZ model

The command stores the name of the Corridor created - the Manage Corridors command will allow recreating a created corridor.

Applying Assemblies, Target Mapping or Parameter Overrides

The software will determine whether to apply Assemblies, Target Mapping or Parameter Overrides to the corridor, depending on the edits made to the cross sections.

• Assembies.  These are created:

  • For the start of each String

  • When when Codes are removed or added to the cross sections.  This is achieved by applying any of the following variations

    • Insert Section

    • Delete Section

    • Delete Sections Outside Selected Code

    • Conditionally Delete Sections

    • Dual Section Batters (Ditches)

  • When adding a Table Drain (Ditch) entry along the length of the String

  • At intersections and where cul-de-sacs or knuckles start/stop (because Codes are being added/removed from the sections)

• Target Mapping.  These are created:

  • When a Code variation is applied to widen a code onto an alignment

  • When a Code variation is applied to set a Code to adopt the offset and elevation of another String

  • when a Code is set to adopt the offset of a polyline (the software will programmatically create an alignment using the polyline geometry

• Parameter Overrides.  These are created:

  • When you apply Variations that manually adjust the crossfall or width based on user typed inputs, such as:

    • Linearly Vary Section Slope or Width

    • Match Code to Surface

    • Match Slopes

  • When you add a Batter (Daylight) override

Mesh Refinement

When a surface is created from a Model, the software adds additional sampling through vertical curves to improve vertical curve accuracy.  If Mesh Refinement is unticked, standard sampling is applied through vertical curves.

Requirements

Before creating the corridor, a Civil Site Design/Corridor EZ Model must be created.  The Auto Model command will create 'TotalModel', which creates a model containing road, curb return, cul-de-sac, knuckle and roundabout strings.  Models can be created using any combination of strings and codes via the Model Builder command.

Any strings created from an alignment (Road, curb return, cul-de-sac, knuckle, roundabout or profile) can be placed in a model and included in the Export Corridor command. 

Grading strings are created from polylines and are not included in the Export Corridor command.

Details

Upon selecting the command the following form is displayed:

Corridor name	Type in a name for the corridor to be created. If the same name is used for a corridor already created, the assemblies and corridor will be recreated.
Model	Use the picklist to select the Civil Site Design/Corridor EZ model to use for exporting the corridor
Apply Mesh Refinement	Adds additional sampling through vertical curves when creating the corridor model
Ignore Parameter Overrides	Toggle on to prevent the software from applying parameter overrides to the corridor
Conversion Settings	Establishes the 'rules' for creating assemblies for Civil Site Design/Corridor EZ templates applied to strings and cross section codes.
Default Conversion File picklist	Select the default conversion file to use for creating Civil 3D subassemblies.  This will be applied if 'Use Tample Assignment' is unticked.
Edit Conversion File	Edits the selected conversion file by opening the Exchange Settings command.
Use Template Assignment	If ticked on, the Setup Templates form is activated to allow assignment of different conversion files per Civil Site Design/Corridor EZ template. If unticked, the Default conversion file is applied.
Setup Templates	When clicked the following form is displayed: Template Lists all the Civil Site Design/Corridor EZ templates used in the project. Conversion File Use the picklist to assign the desired Conversion file per template. Conversion File picklist Select a conversion file to apply it to multiple Templates Apply to Selected Highlight multiple rows in the list and click this button to apply the selected conversion file to the selected rows. Close Save and exit the form
Civil 3D Styles	Set the styles to apply when creating the corridor, alignments and profiles.
Corridor
Style	Pick the Style to apply to the Corridor
Code Set	Pick the Code Set to apply to the Corridor
Alignment
Style	Pick the Style to apply to the created alignments
Label Set	Pick the Label Set to apply to the created alignments
Profile
Style	Pick the Style to apply to the created profiles
Label Set	Pick the Code Set to apply to the created profiles
Export Corridor	Create the assemblies and corridor in the drawing.
Show Log	Tick on to generate a Notepad file detailing all codes found and calculations for the corridor.
Cancel	Exit the form without deleting any data.
