The Length measurement tool places specialized markups that calculate a single, linear measurement. Length measurements can be given depth or a slope.
Before placing a measurement, it is recommended that you calibrate the page scale for the document first. When trying to place a measurement on a page that does not have a page scale, you will be prompted to set the scale.
Go to Tools > Measure > Length or press SHIFT+The Length measurement mode is engaged. ALT+L.
- Alternatively, click Length on the Measurement panel.
- Click the end points of the desired length.
- Hold down SHIFT to draw lines that are at horizontal, vertical, or 45° angles.
- Length measurement arrows will automatically position themselves inside the extension lines when there is enough room, otherwise they will automatically position themselves outside the extension lines.
- 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.
- Slope describes the slope ratio for the measurement, allowing for accurate calculations of materials over a sloped plane. To set a slope, select a unit of measure for it (Pitch, Degree, or Grade) and enter the value in the corresponding field.
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 resize the markup or change its angle, click and drag the appropriate yellow handle. Hold down SHIFT while dragging to force the markup to a horizontal, vertical, or 45° angle.
To adjust the height of the markup, click and drag the middle (caption) control handle.
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 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 rotate the caption 180°, right-click the markup and select Flip Text.
See Editing Markups for more information.
The appearance of the Length measurement is configurable, including its line and fill color, line width and style, opacity, and font characteristics for the caption.
To change the appearance of a Length measurement, select it and click the Properties panel.
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 line pattern.
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 Caption: Select to include caption text on the markup. Click Edit to choose which measurements to include.
Show Caption Leader Line: Select to show the leader line to the caption.
Font: Sets the font used for the selected text.
- 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.
Text Color: Sets the color of text.
The Font Style settings control the formatting of the text. Options include Bold, Italic, Underline, Strikethrough, Superscript and Subscript. Generally, any combination of these styles can be applied to format the text.
