Measurements panel

The Measurements panel provides access to the measurement modes, allows setting the document scale and measurement precision, setting up and clearing Viewports for multiple scales in the same document, and other measurement options.

When you've set the page scale, a preview of key measurement values appears in the lower-right corner as you place measurements to ensure precision. Hide or recall it as needed by selecting the X or the measure icon.

Totals for selected measurements are available in the Markups list and on the Dynamic Properties Toolbar.

Go to Window > Panels > Measurements to show the Measurements panel.

For Revu 21 users, a Basics subscription plan only has access to Length and Area. You must have a Core or Complete subscription to access all measurement tools.

Measurements panel toolbar

The Measurements panel toolbar provides easy access to the measurement modes.

Measurements menu:

Show Measurement Tools: When enabled, measurement tools are shown on the panel toolbar. When disabled, these tools are hidden, though they are still accessible from the Measure Toolbar and the Tools > Measure menu.
Make Annotations from Measurements: When enabled, measurements are created as permanent annotations on the document. When disabled, measurements are temporary. This function is only available for Studio Session PDFs.
Snap Orthogonal: Restricts measurements to angles in 45° increments. This can be temporarily enabled by holding down SHIFT.
Snap to Content: Snaps the cursor to the underlying lines and drawing elements, making it much easier to accurately select 2 points. Only snaps to vector content in a PDF file. Will not snap if the content is an image or a scanned file. The cursor will change to include a shaded square when it is over an element that can be snapped to.

Highlight Viewports: Causes any Viewports on a page to be highlighted in blue anytime a measurement tool is selected.

Length: Calculates a singular linear measurement.

Polylength: Calculates the total length and the length of each segment of a shape or multi-segment line. The corresponding menu also contains the following tools:

Perimeter: Calculates the total perimeter length of a shape or multi-segment line.

Area: Calculates the area of a simple rectangle or of an irregular, polygonal shape. The corresponding menu also contains the following tools:

Polygon Cutout: Cuts out or subtracts a polygonal area from an existing Area or Volume measurement.
Ellipse Cutout: Cuts out or subtracts an elliptical area from an existing Area or Volume measurement.

Diameter: Calculates the diameter of a circular shape.

Angle: Measures a given angle as defined by three points.

Radius: Measures a circle by its radius as described center-out.

3-Point Radius : Measures a circle using any three points along its circumference.

The keyboard shortcut for the radius measurement tool automatically calls the most recently used version of the tool.

Volume: Calculates the volume of an area with a defined depth.

Count: Places a markup for each mouse click, associating a running total of counts with each markup as it is placed.

Dynamic Fill: Automatically creates Spaces and measurement markups from any shape on the content layer of a drawing.

Measurement panel sections

Page Scale

The Page Scale section shows the document scale and measurement precision. To ensure the accuracy of measurements, takeoffs, and so on, check that the scale is set correctly.

Changes made here generally affect all measurements on the drawing, including those made previous to the change, unless the page scale is protected. A warning message will appear at the top of the Page Scale section when this is the case.

When the page scale is protected (most commonly seen in drawings opened from Studio, either from Sessions or from Projects without first checking them out), changes made to the page scale can behave differently than what it described below. See Protected Page Scales below for more information.

Page: Shows the current page.

Add Scale to More Pages: Used to apply the current page's scale to other pages in the drawing.

Scale: The following tools for checking or setting the page scale are available:

Calibrate: Calibrates the scale to a known length on the drawing. This method is particularly useful when one cannot be assured that no scaling errors occurred during the PDF creation process. See Calibrating a Scale to the PDF for more information.
Preset vs Custom: Used when setting a scale for the current page (if the scale is already set, can be ignored). When the scale of the drawing is known and you can be assured that no scaling errors occurred during the PDF creation process, you can set the scale yourself (if you cannot be assured that no scaling errors occurred during the PDF creation process, calibrating the scale to the page is recommended). Revu comes with several of the most common scales preloaded. To use one of these, select Preset and choose a scale from the menu that appears. To set known scale that is not on the Preset list, select Custom and enter the scale manually in the scale definition fields (described below).
Scale definition: The current scale is shown in the form (Measurement A) = (Measurement B). These can be changed manually, if desired, though calibration is generally recommended unless you can be assured no scaling issues occurred during the PDF creation process.
+ Add Preset: Custom and calibrated scales can be added to your Preset list for later use, either on this document of other drawings. Once you have set a scale, select + Add Preset to save it to your Preset list. Saved scales appear at the top of the Preset list.
Separate Y Scale: Select to define separate X and Y scales. If a scale has already been set, it will automatically become the X scale. The Y scale can be set using any method mentioned above and need not be the same as the one used to set the X scale.

Precision: Defines the decimal or fractional precision of the measurement values.
