You can use the measurement tools to measure and analyze the lengths of lines on plan documents. To open the Measurement toolbar, click the Measurement option from the toolbar.
The Measurement toolbar is displayed.
Click the Line Measurement option to measure the distance between two points on the document. With this option selected, click and drag on the document to create a line. The length of the line is displayed in the Scale and Measurements section of the toolbar. Use the available drop-down lists to change the unit of measurement used to measure the line.
Click the Polyline Measurement option to measure the distance of a line with multiple points and the area of the shape. With this option selected, click and drag on the document to create a line. Left-click to add another point to the polyline, or right-click to place the final endpoint. Hold CTRL while right-clicking to create a final line segment linking the endpoint to the first point created, thereby closing the polyline.
Only shapes closed using CTRL + Right-click can be used to calculate the area of the shape. Manually placing the final line segment in such a way as to appear to close a shape does not link the line segments together and cannot be used to calculate the area of the shape.
The length of the entire line or polyline is displayed in the Scale and Measurements section of the toolbar, and the area of closed polyline shapes is displayed in the Measurements section only. Use the available drop-down lists to change the unit of measurement used to measure the line and calculate the area. Use the drop-down list next to the Enable Snap To Points option to change the color of the line being drawn.
Select the Snap To Points option to display the closest SnapTo locations that can be used with the measurement tools. SnapTo locations are displayed on the document as blue shapes. When a SnapTo location is displayed on the document and a measurement tool is used to start or finish drawing a measurement near that location, the SnapTo location is used instead of the exact mouse position. Deselect the Snap To Points option if you need to select a specific location on the document when creating measurements.
When the Snap To Points option is selected, the End Points and Mid Points options are enabled. Select the End Points option to enable the ability to snap to end point SnapTo locations on the document. Select the Mid Points option to enable the ability to snap to mid point SnapTo locations on the document.
OnBase creates SnapTo locations by analyzing the document to find relevant points. Not all likely locations are discoverable, so users may find it necessary to use manual selection to measure between two points accurately.
SnapTo locations are not available on secured PDF documents that were created without enabling the Enable copying of text, images, and other content option.
