Using the Points Tool

The Points annotation tool lets you add a series of points to the 2D views or 3D view in a scene. A points set can include any number of points and the information provided for each point includes its position in the world coordinate system, as well as the intensity and voxel position extracted from all underlying datasets. You can also add captions to each point within a set to annotate your findings, as shown below.

Points set

In addition, a number of functions are available for points sets, such as aligning views, creating rulers, and fitting cylinders and spheres (see Annotation Pop-Up Menu).

1. Click the Points tool  in the Annotate panel.
2. Hold down Left Ctrl and then click on the image to add the first point in the set.

   The coordinates of the point and its native value appear in the Basic properties box on the Data Properties and Settings panel. If required, you can add a caption to the point.

3. Add additional points, as required.
4. Do the following to reposition points, if required:
   • Select the required point(s), either directly in a view or in the Basic properties table.
   • Click inside a selected point and then drag to reposition the point(s).
