Measure line/circle/angle, Show recorded

Purpose

Use the measurement tools to measure in the Main window.
They can also be used to test lens calibration.
Neurolucida software does not save measurements to the data file; they are recorded and available during the current session only.
Click Show Recorded to view your measurements, and to print or copy them to the clipboard.

To view, print, or copy measurements to the clipboard, click the Show recorded button; this opens the Quick Measurements window where measurements are recorded.
To exit the measurement tools, click the tool icon to deselect it, right-click and select Stop Quick Measurements, initiate another action (e.g., Align tracing or Move To), or press the ESC key on your keyboard.
By default, the measurement tools operate in continuous mode—once you click a measurement tool icon, it remains active until you exit the tool as described in the previous bullet. In continuous mode, you can quickly take multiple measurements successively.
Exit continuous mode by right-click and de-selecting Continuous. With continuous mode de-activated, you'll need to click the measurement tool icon each time you want to take/record a measurement.

Tips for the measure line tool:

To adjust your origin point, press the SHIFT key and drag the line.
To constrain the line to 22½° increments, press the CTRL key. This is helpful for drawing perfectly horizontal and vertical lines.

Click Measure line.
Click one end of the line, move your cursor and click again to indicate the other end of the line.
The measurement is displayed and recorded.
Click OK to take another measurement.

Click Measure line.
Click the point of origin.
Position the cursor over the first end point and press F8 on your keyboard to record a measurement. The "rubber line" remains anchored at the point of origin.
Position the cursor at the end of another line and press F8 to record the new length. Repeat as many times as desired.

Each value is recorded; click Show recorded to view.
To complete, press the ESC key or click (rather than pressing F8) to indicate the end of a line.

Click Measure line.
Click the point of origin.
Use the field move arrows (on the Move ribbon) to move to the field of view with the end of the line that you want to measure and follow the instructions above to take a single measurement or multiple measurements from a single point.

Click Measure circle.
Click the center of the circle.
Drag the mouse to draw the circle and click again to indicate the extent of the circle.
Click to view and record measurements, including radius, diameter, circumference, area, and volume.

This tool measures an angle defined by three points.

Click Measure angle.
Click and drag the mouse to draw the first line of the angle.
Click again to indicate the vertex of the angle.
Drag the mouse to draw the second line and click again to end. The angle is displayed in degrees and radians.

Measurements are recorded for the duration of the session; they are not saved to the data file.
