Area measurement

1. Select Tools > Measure > Area.
2. Set depth, slope, or change units from the Properties toolbar or the Measurements panel:
   • To set depth, enter a value in the Measurement Properties section of the Measurements panel and choose the units. Setting a depth for the measurement allows for additional calculations like Wall Area on the Markups list.
   • To set slope, enter a value in the Measurement Properties section of the Measurements panel and choose the units. Setting a slope for the measurement allows for additional calculations like materials over a sloped plane.
   • To change the units for any dimension, select the desired measurement units from the dropdowns in the Measurement Properties section of the Measurements panel. Measurements can be taken in units different from those used to set the page scale.
   • Any or all of these can also be set from the Units dropdown menu on the Properties toolbar.

   Changes you make to properties will apply to all new measurements until you switch tools (for example, when you place a different type of measurement).

3. Select each point in your shape to define the area.

   • To remove the last control point, select Backspace.

4. Close the shape by doing the following:

   • Select Enter after placing the last point.
   • Double-click when placing the last point.

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.

Tips:

• Hold Shift to draw lines at horizontal, vertical, or 45° angles.

• Drag to place a rectangular shape. Holding Shift while doing so will force the rectangle into a square.

• Change properties (Subject, Label, units, Slope, Depth) after placing the measurement by selecting it and using the Measurements panel.

To remove markups from your PDF, do one of the following:

• Select the markup on the PDF or from the Markups list.
• Press Delete on your keyboard, or right-click and select Delete.

Control points define where line segments meet in a multi-segment markup. Add or remove control points to adjust the shape. See Working with Control Points for more information.

Convert line segments to curves or arcs at control points to match complex shapes. See Working with Curved Markups for more information.

You can add an action to almost any markup. Right-click the markup and select Edit Action.

Markups may display indicator icons below and to the right of the markup (or grouped markups). These include:

Action: Shows that an action is defined for this markup. Select to trigger the action.

Capture: Shows that the markup has embedded media (typically an image or video). Select this icon to open a preview window.

Reply: Shows one or more replies exist in the Markups list. Hover to preview replies or select to jump to the markup's entry. Turn off the ability to see reply indicators in the View menu.

Select a markup to reveal its control handles. Each handle controls a different aspect of size and orientation.

Rotate the markup: Drag the orange handle outside the markup (default: 15° increments; hold Shift for 1° increments)

Rotate the caption: Drag the orange handle directly over the caption.

Move only the caption: Drag the caption while holding down Shift. To return the caption to its default position, right-click it and select Reset Caption Position.

Move the entire markup: Drag any part except the control handles.

Resize a segment or change its angle: Drag the appropriate yellow handle.

Scale the markup up or down: Drag the appropriate purple handle.

• Rectangular and square markups don't have purple handles. To scale these markups, hold Ctrl and drag a yellow handle at any of the corners.

See Editing Markups for more information.

The appearance of the Area measurement is configurable, including line and fill color, hatch pattern, line width and style, opacity, plus the font style of the caption and whether or not to show it.

To change the appearance of an Area measurement, select the markup and select the Properties panel. Go to Window > Panels > Properties to show the Properties panel if it is hidden. Several properties will also be available on the Properties toolbar when the markup is selected.

Appearance properties

Color: Sets the line color.

Fill Color: Sets a fill color.

Highlight: Makes the fill color and/or hatch pattern transparent so underlying content shows through.

Hatch: Sets a hatch pattern. The associated color selector sets the line color of the hatch pattern.

Scale: Sets the scale of the hatch pattern, from 50 (half the default scale) to 200 (twice the default scale).

Opacity: Sets opacity level of the line and endpoints, from 0 (invisible) to 100 (opaque).

Fill Opacity: Sets the fill and hatch pattern opacity, from 0 (invisible) to 100 (opaque).

Line Width: Sets the line thickness in points. A setting of 0 effectively renders the line invisible.

Style: Determines the line pattern. In addition, there are several advanced line styles and you can create Custom Line Styles.

Show Segment Values: Display segment lengths. Choose an alignment for these captions:

• Align to Segment: When selected, segment length captions will follow the segment line when it is rotated.
• Align Horizontally: When selected, segment length captions will always be horizontal, regardless of the markup's rotation.

Show Caption: Display caption text. Select Edit to choose which measurements to show.

Show Centroid: Display the geometric center. If necessary, the caption will be automatically adjusted to be below the centroid.

Font: Sets the font used for the selected text. Available fonts are divided into three regions:

• The first region shows all fonts used in the currently selected text element.
• The second region lists the standard PDF fonts that are supported by all PDF viewers. These fonts don't need to be embedded in the PDF when used, thereby cutting down on file size.
• The third region shows all other available fonts. When used, these fonts need to be embedded in the PDF.

If you attempt to embed a font for which the viewing and editing permissions do not allow formatting, Revu will display a message indicating the font will not be embedded in the PDF.

Font settings are retained in the PDF and will substitute as needed if the original font is unavailable.

Font Size: Sets the font size for text. You can choose a size from 2 to 72 points in the list, or enter any value from 1 to 144 points manually. You can also use decimal values with one digit after the decimal point.

Text Color: Sets the color of text.

Font Style: Control the formatting of the text. Options include Bold, Italic, Underline, and Strikethrough. Generally, any combination of these styles can be applied to format the text.
