Calibrate Bluebeam scale in 30 seconds on a Volanti plan table
Quantity take-offs start with an accurate scale. If that scale is off by even an inch, your estimate falls apart. This walkthrough shows project estimators how to lock a drawing to real-world dimensions in Bluebeam Revu using the Volanti Plan Tables 43" and 55" and 65". No rulers, no guesswork, just true numbers in forty-five seconds.
Step-by-step instructions
| Step | Action on the Volanti touch desk |
|---|---|
| 1 | Open the drawing in Bluebeam Revu. Tap the maximize icon so the sheet fills the screen. |
| 2 | Tap Measure › set scale > Calibrate on the top toolbar. Cross-hairs appear. |
| 3 | Single-tap the first end of a known dimension line (for example a 20 foot grid). |
| 4 | Single-tap the second end of that line. The Calibration dialogue box opens. |
| 5 | Type the real-world length (e.g., 20 ft) on the on-screen keyboard and tap OK. |
| 6 | Test the calibration: select the Length tool and drag along a wall. The measurement now displays the true value. |
| 7 | Save the file. Bluebeam stores the scale with the sheet so every new measurement stays accurate. |
Pro tip
For multi-sheet sets, run Calibrate › Apply Scale to Pages and pick the page range. Every sheet with the same printed scale locks in instantly.
Correct quantities first time – no manual conversions later.
Faster bids – measure once, trust the number, move to the next sheet.
Shared accuracy – the saved scale travels with the PDF, so every trade works from the same baseline.
