Measurement tools

The Tools menu displays different types of measurement tools.

Point measurement

The point measurement tool prints the coordinates of a picked point to the BubbleView or 3D view display. Select the required point with the left mouse button.

As shown below, coordinates are displayed alongside the selected point and also in the Measurement Tab Attributes Window.

Selecting the Measure Point icon brings up the Actions tab as shown below:

The Edge feature enables you to measure points at the edges of the walls, pavements and points at the intersection between planes.

To enable edge detection, select Edge and hover over a corner or an edge surface. The measurement state brings up semi-transparent planes that cover the creases and corners, thus forming 2-planes (for creases) and 3-planes (for corners) respectively. You can then measure from the creases and corners that have been created. When Edge Patch is enabled along with Edge, a semi-transparent blue square is formed around the area that is selected. Moving the mouse wheel then dynamically changes the size of the patch, thereby enabling you to determine the corners. Scrolling the mouse wheel when Edge Patch is disabled will zoom you into the data.

Note: The edge detection features appear under the Actions tab when performing Point, Distance and Chained measurements. This works both in Points and Solid Point Cloud views.

Distance measurement

The distance measurement tool gives the linear distance between selected picked points.

Selecting the Distance icon brings up the Actions tab as shown below:

Steps to perform a distance measurement:

1. Select the distance measurement icon.

2. Click to select the first point to measure. If the Edge feature is enabled, semi-transparent squares are formed around the creases and corners, enabling to make accurate corner-to-corner measurements.

3. Click to select the second point and finish the measurement.

4. Measurement values appear in the BubbleView or 3D view windows and Measurements Tab Attributes Window.

After selecting the measurement start point a cutting plane appears which tracks the movement of the mouse cursor until the measurement end point is selected. This gives the user a sense of depth as the cutting plane appears behind objects/points that are in front of the measurement.

After selecting the end point, the measurement is displayed in the BubbleView or 3D view as a blue line with a diamond at each end. Clicking on the diamonds shows the x,y,z coordinates of the point. Clicking on the line displays the total point-to-point distance but also a measurement component frame.

This measurement component frame is interactive, enabling you to click on each of the measurement component lines to see the planar measurement for each axis.

Measurements are logged in the Measurements Manager.

Chained measurement

The chained distance tool allows a measurement across multiple points to be taken. Select points with the left mouse button, then finish the measurement with a right-click.

Selecting the Chained icon brings up the Actions tab as shown below:

After the measurement is complete, it appears in the BubbleView or 3D view as a blue line. The measurement can be interacted with in the following ways:

• Click on the diamonds showing the start or end point – displays the x,y,z coordinates and the total distance.

• Click on one of the lines – displays the distance of that line, the total distance and the measurement component frame for that portion of the measurement.

• Click on the intermediate diamonds – displays the x,y,z coordinates, angle at point and total distance.
