:rocket: Custom SketchUp Tool: Geodetic Elevation Tracker

I got tired of doing mental math for site elevations while modeling, as I work in ft and inches but need to note these details in meters so I built a custom Ruby extension to handle it. Here’s a quick breakdown of how it works:

  • Zero-Offset Modeling: It allows you to keep your model at $0,0,0$ (avoiding camera clipping and graphics glitches) while reporting real-world sea-level elevations.

  • Live Dashboard: The HTML window lets you set a Datum Offset (e.g., 401m). As you move your cursor, it live-calculates the Geodetic Elevation in meters, even if your model is in imperial units.

  • One-Click Labeling: Clicking any point drops a native SketchUp text leader with the calculated “RL” (Reduced Level).

  • Dynamic Global Updates: If the site benchmark changes, you just update the datum in the dashboard and hit “Update All Existing.” Every label in the model recalculates instantly to the new height.

It’s been a game-changer for site plans and coordinating subfloor levels with contour lines
