TIN Terrain

TIN Terrain

TIN terrain is the preferred terrain input path for v1.

Purpose

TIN terrain provides existing-ground context for:

• Profile review
• Applied Sections
• Build Corridor
• Earthwork
• future drainage checks

Workflow

1. Open the TIN command.
2. Load or prepare terrain data.
3. Review the terrain surface.
4. Use it as the accepted existing-ground source for downstream workflows.

Downstream Use

Applied Sections and Earthwork should read terrain through v1 terrain/TIN contracts instead of relying on ad-hoc viewer geometry.

If Earthwork reports missing existing-ground terrain, confirm that a valid TIN exists and is available to the active project workflow.
