Using different units of measurement on the same drawing | Revu 2017 & below

There are times when you’ll need to use separate units of measurement on the same page. For example, you might need linear measurements in feet-inches, and volume measurements in cubic yards (e.g. for concrete or dirt).

Make sure the page is calibrated

It’s always a good idea to make sure the page is properly calibrated before taking any measurements. If you’re not sure that it is, please follow these steps listed below. Otherwise, skip to the next section.

  1. Locate a known length on the page.
  2. Open the Calibrate tool using one of the following methods:
    • From the Command bar, go to Measure > Calibrate measure-calibrate.
    • From the Scale section of the Measurements measure tab, click Calibrate.
  3. A dialog box might appear with instructions. If it does, click OK.
  4. Click the first point of the known length, then click a second point to finish the line. Hold down the Shift key to snap the two points horizontally, vertically or diagonally (as appropriate). When the second point is selected, the Calibration dialog box opens.
  5. Enter the distance that the line between these two points represents on the drawing and select the units in which measurements are to be reported.
  6. Click OK.
Scales, units of measurement, and Store Scale in Page are set on a per-page basis. So if you’re working with a multi-page PDF, you’ll need to make sure you set them for each page.

Now, remember that the unit of measurement used when calibrating the drawing will be the default for all measurements on that page. Up next, we’ll define separate units of measure for Area and Volume.

Define separate units of measurement for area and volume

You can set independent units of measurement for Area and Volume; which will exist separately from each other, and the default unit of measurement used for linear measurements.

  1. Click the Measurements measure tab.
  2. Select Independent Units. Selections for Area Unit and Volume Unit appear.
  3. Select a unit of measure for Area Unit and Volume Unit.
  4. To keep this configuration when the PDF is saved, select Store Scale in Page. Otherwise, these settings will be discarded when the PDF is closed.

    If the Store Scale in Page option isn’t available, scroll down to the Options section of the Measurements tab and select Use Embedded Scale.

The Store Scale in Page function works on a per-page basis. So if you’re working with a multi-page PDF, you’ll need to make sure you set it for each page.

Independent units can be applied to areas and volumes retroactively. To recalculate a previously measured area or volume with a newly set unit of measure, just click Recalculate (as always, if you’re not sure the page is properly calibrated, it’s a good idea to calibrate it first). All measurements on the page will be recalculated with the current units of measurement.

Take your measurements

Once the Independent Units are set up, your Area and Volume measurements will use the units of measurement you’ve selected . All other measurements will utilize the unit of measurement selected when calibrating the page.

Some documents need to use separate units of measurement on the same page. Learn how to use separate measurement types within the same document.
