Revit Tip: Revit North Alignment: Project North vs True North Best Practices

Correctly aligning True North and Project North keeps documentation clean while preserving accurate site orientation for analysis and coordination.

Key concepts

• Project North: Orthogonal orientation optimized for modeling and documentation (grids, dimensions, sheets).
• True North: Geographic north used for site context, sun studies, and shared coordinates.
• Keep your building orthogonal to Project North; rotate only the True North orientation or the site link to avoid skewed drawings.

When to set orientation

• After levels/grids are established and before major documentation begins.
• As soon as you receive a survey/site model, or prior to solar/energy analysis.
• Before issuing coordinates to consultants.

Recommended workflow

1. Link the survey/site file (Revit or DWG) with correct units and positioning (Auto – Origin to Origin or By Shared Coordinates once available).
2. Create a dedicated Site Plan view and set View Properties > Orientation = True North.
3. If the site model is authoritative, use Manage > Coordinates > Acquire Coordinates from the site link. This writes the shared coordinate system (including angle to True North) into your project.
4. If your building model is the host, use Manage > Coordinates > Publish Coordinates to the site link so everyone references the same shared coordinates.
5. To manually set north without a site link:
   • Set a known reference using Manage > Coordinates > Specify Coordinates at Point on a survey monument.
   • Use Manage > Position > Rotate True North to match survey bearings (do not rotate the building).
6. Verify in the Project Base Point: confirm Angle to True North and spot-check with a Spot Coordinate/Spot Elevation.
7. Apply View Templates:
   • Docs – Project North for plans, RCPs, elevations.
   • Site – True North for site plans, sun studies, and coordination.

Quality checks

• Sun study at local solar noon: shadows should point due north-south as expected.
• Cross-check bearings against survey notes (e.g., “N 12°34’56” E”).
• Export a test NWC/IFC and verify coordinates/orientation in downstream tools.

Common pitfalls (and fixes)

• Rotating model geometry: Don’t. Rotate True North or the site link instead.
• Moving the Survey Point clipped: Avoid. Use Specify Coordinates at Point or Acquire Coordinates to establish geolocation safely.
• Unclear ownership of shared coordinates: Establish who is “source of truth” (survey vs building) and Acquire/Publish accordingly.
• Mixed orientations in documentation: Enforce View Templates so sheets stay orthogonal while site views show True North.

Handoff and coordination

• Communicate the shared coordinate status and angle to True North in your BIM Execution Plan.
• When models are federated, confirm all links are set to By Shared Coordinates to eliminate rotation/translation drift.
• Re-run Acquire/Publish if the survey is revised.
