How to make an inspection plane
- Select the data object you would like to dimension.
- Change the main viewport – or if using split-views, the leftmost viewport – to one of the cardinal 2D slice axes, a revolving slice plane, or custom slice plane. In the latter two cases, you can also click on the revolving or custom slice plane in the data panel.
- Find the slice you want to inspect by dragging the slider to the desired position at the bottom of the viewport, or in the attributes panel of the object.
- Click on the inspection plane button to create the new data object, which locks that plane in for inspection.

Accessing or editing an inspection plane
There are two ways to access inspection planes. Through the Data Panel (a)- Expand the reconstruction or ROI object to see associated data.
- Select the Inspection Plane data object
- All inspection planes are an option in the view dropdown.

Dimensioning an inspection plane
- If not already selected, click on an Inspection Plane to bring it into the main view
- Use dimensioning tools to assign persistent dimensions on the plane.
- Line – select two points to start and end the dimension, then click to drop the label.
- Circle – select three points to define the circle (all perimeter) and then click to drop the label.
- Angle – select four points, the first two clicks defining one line and the following two clicks to define the next. Click to drop the angle label. The location of the label determines which angle is being measured (acute or obtuse).
- Modify the labels as needed in the Attributes panel.
