Setting Up a Polylines Project
Updated at August 6th, 2025
This document outlines the correct steps to configure a polyline annotation project using orthographic shapes.
Key Configuration Requirements
- Enable Accumulated Ground Setting
- Must be enabled before task creation.
- Tasks created before this setting was turned on will not have the accumulated mesh, and grounding will fail.
Reminder: Editing tasks or cloning them without enabling the setting first will still result in missing mesh data
Task Creation Guidelines
Always Create Tasks From Original Assets
- After changing pre-processing settings, do not reuse tasks via JSON export/import.
- Reimporting JSON will reuse old pre-processed assets (using outdated settings).
Outputs and Shape Association
Shapes Must Be Linked to the Correct Output
- Orthographic shapes must be associated with the point cloud output.
- They won't appear in final exports or may be misreported if they are linked to the video output (like orthographic_annotation).
This misconfiguration happened due to transitions during the early implementation of objects + sensor fusion.
Output Visibility
- By default, orthographic_annotation is set to “Hide from deliveries”.
- You must uncheck "Hide from deliveries" to make shapes appear in the export.
- Navigate to Project Settings > Outputs and disable “Hide from deliveries” for the orthographic output.
Troubleshooting & Recovery
Missing Shapes in Export?
- Possible cause: Shapes are not associated with an output (orphaned).
- This can happen if:
- An output was deleted and recreated.
- Shapes were created when the wrong output was selected.
- Fix:
- Reassign shapes to the correct output (point cloud) via workspace repair.
- In urgent cases, export shapes from the video output and reassign them offline.
Notes on Reporting
- If shapes are linked to a video output, reporting will not reflect them under the expected point cloud output.
- For trial deliveries, reporting discrepancies may be acceptable, but fix them before production if the deal progresses.
Recommendations
Maintain a checklist to ensure:
Tasks are created from original assets Orthographic shapes are linked to the correct output Outputs are visible in deliveries Proper export validation is performed before delivery
