Point to Point measurement

Point to Point measure

The Point to Point measure tool measures the distance between two scene object points.

• When the tool is activated, a distance indicator displays over the mouse position that enables you to identify a picked point and its distance from the observer.

• The Point to Point line measurement displays on the center of the measurement line along with the measurement name.

Note Measurement labels are hidden when the camera is moved away from measurement line and appears again when the camera moves close to the measurement line.

Perform a point to point measure

1. Click Measure on the toolbar.

   

2. On the pop-up menu, select Linear.

   

3. On the Linear context menu, click Point to Point. Alternatively, you can press shortcut key Q.

   

4. Identify and click the starting point with the mouse. The distance to camera indication disappears and the point-to-point distance appears. When you click on the starting point, a sphere appears at the start of the measure line and the measure line appears in red color while drawing.

   

5. Move the mouse to identify the end point. The point-to-point distance indicator follows the mouse. This helps to correctly identify the end point. A line is shown connecting the start point and the mouse position.

6. Click the end point. The point-to-point distance indicator moves to the center of the line. The distance to camera tool appears again. When you click the end point, the second sphere appears at the end of the line.

   

7. When the measure line is confirmed, spheres will be hidden and the line will turn to blue color.

   Note: The line is confirmed either by exiting the measure tool, or starting to draw a new measure line.

   

Guidelines about point-to-point measurements

When making a point-to-point measurement, both the start point and end point must be in valid locations.

It is not valid to:

• Click on an existing measured line segment.

• Place either start point or end point in the sky.

When using Lock mode

Lock mode constrains the drawing of the measurement to the Y axis.

It is valid when drawing a vertical line with Lock mode enabled to choose an end point in the sky; however, not the starting point.

Delete a measurement

8. Move the mouse over the line of the measure to be deleted. The line becomes thicker confirming selection.

9. Click the mouse over the line to remove it.
