Workflow for Corridor Data Preparation

The primary goal in preparing data for a corridor is to create high-accuracy surfaces for measurement and stakeout on controllers running Site Controller Software (SCS) or grade control operations on machine control systems. A secondary goal may be to create a variety of surfaces for corridor takeoff calculations. This page guides you through the steps needed to create corridor models for these purposes.

Note: Your tasks may vary from these typical steps, so feel free to use commands in a different order or skip steps.


Steps		Help by Command
1.	Work through the steps for creating a corridor.	Workflow: Create a Corridor
2.	Clean up your imported data to fix typical problems found in CAD data.	Project Cleanup
3.	Review your data using the View Filter Manager: Isolate mode with extents on Identify unneeded data	View Filter Manager
4.	Organize your data by layer: Create new layers and rename existing layers. Relayer remaining objects so they are logically segregated.	Layer Manager
5.	Delete unneeded objects.	Delete
6.	Delete unneeded layers.	Layer Manager
7.	Edit the lines in your data by breaking, trimming, extending, and deleting segments. Then simplify the remaining lines by joining them.	Break Line Delete Line Segment Trim/Extend Lines Join Lines
8.	Manually create missing objects: Create stored cross-sections from CAD drawings Digitize stored cross-sections	Create Stored Cross-sections from CAD Drawing Digitize Stored Cross-sections
9.	Check your data for accuracy: Review the elevation at any distance along a line. Measure distances and angles between objects. Exaggerate vertical distances and orbit around contours and other lines in 3D. Review the attributes of any object.	Explore Object Measure Measure Angle 3D View Settings 3D View Properties pane
10.	If needed, proceed to one of the other workflows.	Workflow: Perform a Corridor Takeoff Workflow for Managing SCS Data Workflow for Managing GCS Data
