    Check Coordinates

    Video tutorial

    Overview

    Check Coordinates is a read-only georeferencing audit. It compares the host model against every loaded Revit link on three coordinates — Survey Point, Project Base Point, and Angle to True North — and flags each link Aligned or Not Aligned against a tight tolerance. The left panel shows the host model's identity and coordinates (site name, time zone, latitude/longitude, Survey Point, Project Base Point, and angle); the right panel shows one card per link with its values and status, plus a summary of aligned vs. not-aligned links. The report exports to Excel or PDF.

    How to use

    1. In the B45 Labs | Coordination tab, open the QA/QC panel and click Check Coordinates.
    2. If the host model is still on default coordinates (Survey Point, Project Base Point, and Internal Origin all at zero), a prompt lets you cancel or proceed anyway — proceed only to inspect, since the numbers aren't yet meaningful for coordination.
    3. Read the left panel for the host model's identity and coordinates; read the right panel for one card per loaded link.
    4. Check each link card's Survey Point, Project Base Point, and Angle to True North — each is marked Aligned or Not Aligned against the host.
    5. Use the summary to see how many links are aligned vs. not, and which unloaded links were skipped — they appear as amber cards, excluded from the totals.
    6. Export the report to Excel or PDF for a coordination record.

    Tips & Notes

    • Load every link you want checked first — unloaded or inaccessible links can't be read, so they're reported but excluded from the aligned/not-aligned totals.
    • Run it before each model submission; a single Not Aligned card is enough to hold a delivery until the shared coordinates are reconciled.
    • Alignment uses a tight tolerance — about 1/8 inch on position and a hundredth of a degree on angle — so a Not Aligned card is a real mismatch, not rounding.

    Limitations

    • Reports alignment only — it never moves or corrects any point.
    • Compares against loaded Revit links; CAD links and unloaded models are not analyzed.
