Exploration of data reference corridors

Create data shortcut

In source drawing containing Corridor Object, create the data shortcut.

1. Toolspace > Prospector > Right-click Data Shortcuts > Create Data Shortcut
2. Under Corridors select the Corridor and OK

Create reference

When creating a data reference of a corridor, all baseline objects will be referenced as well. This include all alignments, profiles, and/or feature lines used as baselines.

1. Toolspace > Prospector
2. Expand the project
3. Expand corridors
4. Right-click on the corridor > Create Data Reference

5. Accept the style defaults

The corridor and all associated baselines will be inserted into the drawing. The baselines (alignments) will adapt the styles described in the create alignment reference drawing settings.

The corridor can be data referenced into a cross section sheet file and sampled into section views.

1. Start a new drawing using the WisDOT Design Template.
2. Create data references to the following objects:
   1. Existing surface
   2. Design refinement surfaces (Top and Datum)
   3. Corridor
      1. Since the alignments are referenced when a corridor is referenced, they do not need to be referenced again.
3. Create Sample Lines
   1. Home Tab > Profile and Section Views Panel > Sample Lines
   2. Sample the corridor, existing surface, and design surfaces.
      1. Recommended corridor code set style: XS Sheets with Shapes
4. Create Section Views
   1. Home Tab > Profile and Section Views Panel > Section Views > Create Multiple Views
5. Create Section Sheets

After creating a data reference of a corridor, the feature lines that make up certain parts of surfaces can be extracted and used as breaklines to create design surfaces.

Corridor surfaces can also be made from the feature line codes in the data referenced corridor properties.

Extracted feature lines could be used as targets in a secondary corridor or as a baseline in a secondary corridor.

Possible Uses

• Construction Staging
• Lane Shifts
• Intersections
• Cul-de-Sacs
• Roundabouts

• Divided Highways

General Workflow

1. Create data references to the following objects:
   1. Corridor (since the alignments are referenced when a corridor is referenced, they do not need to be referenced again.)
2. Extract feature lines to be used
   1. Select corridor > Launch Pad > Feature Lines from Corridor
   2. Select the feature line to be extracted
      1. Command Line: Choose the part of the corridor to be extracted.
      2. Enter to select only the feature line selected
      3. All selects all feature lines in the corridor
   3. Extract Corridor Feature Lines Dialog Box
      1. Assign a site if desired
      2. Choose the Style to be assigned to the feature line.
      3. Adjust the layer if desired
      4. Enter Settings
         1. Dynamic Link: Checked
         2. Apply Smoothing: Unchecked
         3. Name: Not required, but perhaps helpful
3. Freeze the Data Referenced Corridor Layer or hide the corridor if so desired
4. Create the new corridor, using the extracted feature line as a baseline.
   1. Extracted baselines may also be used as targets in a secondary corridor

This exploratory use case utilizes the corridor data reference as a vehicle to essentially data reference feature lines from one drawing to another.

Option 1:

1. Create a corridor and add the feature lines as baselines. (No regions are needed)
2. Create a data shortcut for the new corridor.
3. Open a new drawing and create a data reference of the new corridor.
   1. The baselines (feature lines) used in the definition of the corridor will be inserted into the drawing as alignments and profiles.

Option 2:

1. Create an assembly
   1. Contains one "MarkedPoint" subassembly
2. Create a corridor
   1. Create a baseline and region (using above assembly) for each feature line to be referenced.
3. Create a data shortcut for the corridor
4. Data reference the corridor into a new drawing
   1. Alignments are created for the Feature Line Baselines. Freeze or hide the alignments if desired.

5. Extract the feature lines from the corridor

This process may be simplified using Dynamo. Are there any workflows where this could be useful?
