Perimeter Measurement

1. Go to Tools > Measure > Perimeter or press SHIFT+ALT+P. The Perimeter measurement mode is engaged.
   • Alternatively, select Perimeteron the Measurement panel.

2. Click on each point of the desired shape.

   • To remove the last control point, press BACKSPACE.

   • Note that, if the Show Segment Values is enabled (either by clicking on the Measurement panel or by enabling that option on the Properties Panel), the length of the segment currently being placed is shown as well as the measurement's cumulative length. Segment length is shown over the segment itself while the cumulative length is shown on the opposite side of the cursor. The exception to this is when placing the first segment, when the segment length and the cumulative length are the same and only one value is shown.

3. To "close" the shape, do one of the following:
   • Click the first point again.

   • Press C on the keyboard to automatically close the shape by connecting the last point placed to the first point placed.

   Note: Even though their start and end points can touch, Perimeters are always considered open shapes and will behave as such. For a closed-shape measurement, see Area Measurement.

4. To complete the shape without "closing" it, do one of the following:
   • Press ENTER after placing the last point.
   • Double-click when placing the last point.

Tips:

• Hold down SHIFT to draw lines that are at horizontal, vertical, or 45° angles.

• Click and drag to place a rectangular shape.
  • Holding down SHIFT while doing so will force the rectangle into a square.

• Click the markup so it is active. In the Measurement Properties section on the Measurement panel, certain fields are available to add detail and dimension to the markup, including:
  • Depth allows for additional calculations, such as wall area or material volume, on the Markups list. To set a depth for the markup, enter a value and select a unit of measure.
• Segments of a the measurement can be split from the original markup. To do so, right-click the desired segment and select Split. To break a the measurement into its segmented parts, select Split All.

To remove markups from a PDF, select the markup or markups on the PDF or from the Markups list and do one of the following:

• Press DELETE on the keyboard.
• Right-click and select Delete.

A control point defines where two line segments meet in multi-segment markups. Control points can be added or removed from these markups. See Working with Control Points for more information.

Further, the line segments of these markups can be converted to curves or arcs at their control points, allowing them to conform to nearly any shape. See Working with Curved Markups for more information.

You can add an action to nearly any markup. Simply right-click the markup and select Edit Action to open the Action dialog box.

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

To rotate the markup, click and drag the orange handle outside the markup (when the markup is first placed, it will be at the top). By default, the markup is rotated in increments of 15°; to rotate in increments of 1°, hold down SHIFT while dragging.

The rotation can also be entered in the Rotation field found in the Layout section of the Properties panel.

To rotate the caption, click and drag the orange handle directly over it. By default, the markup is rotated in increments of 15°; to rotate in increments of 1°, hold down SHIFT while dragging.To return a rotated caption to its original position, right-click it and select Reset Caption Position.

To move only the caption, click and drag it while holding down SHIFT. To return the caption to its default position, right-click it and select Reset Caption Position.

To move the entire markup together, click and drag a part of it other than the control handles.

To resize a segment or change its angle, click and drag the appropriate yellow handle.

• Hold down CTRL while dragging a yellow control handle to curve the lines attached to it. See Working with Curved Markups for more information.

To scale the markup up or down, click and drag the appropriate purple handle.

See Editing Markups for more information.

The appearance of the Perimeter measurement is configurable, including line color, style, width, and opacity, as well as the font style of the caption and whether or not to show it.

To change the appearance of a Perimeter measurement, select it and click the Properties panel. Go to Window > Panels > Properties or press ALT+P 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: Controls the fill color of the endpoints.

Highlight: Makes the fill color and line transparent so underlying content shows through.

Opacity: Sets opacity level of the line and endpoints, 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 pattern of the line segment.

Start and End: Controls the appearance of the endpoints for each side of the line. The diagram below shows samples of each type of endpoint.

Each endpoint has an associated Scale that determines the size of the endpoint in relation to the Line Width. By default, it is set to Auto and will automatically adjust as the Line Width is changed.

Show Segment Values: Select to show the segment lengths on the markup. Select 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: Select to include caption text on the markup. Click Edit to choose which measurements to include.

Show All Measurements: Select to include all measurements applicable to the markup, not just the default measurement.

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 do not need to be embedded in the PDF when used, thereby cutting down on file size.
• The third shows all other available fonts. When used, these fonts need to be embedded in the PDF.

Note: 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 parameters are retained in the PDF such that even if the original font is not embedded or on the viewer's workstation, a suitable representation of the font will be substituted.

Font Size: Sets the size of the font. While the list shows sizes ranging from 2 to 72, font sizes between 1 to 144 points are supported; just enter the desired size manually. Also, values with up to one digit after the decimal point can be used.

Text Color: Sets the color of text.

Font Style: These settings 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.
