You can associate 3D measurements with specific views. If the default view is active when a measurement is added, a
new measurement view is created. This view is added to the view hierarchy in the Model Tree. The measurement is
associated with that view only. The measurement shows up as a child of the view.
You can also display comments while taking measurements. These comments (also called measurement markups) are
preserved after the document is closed.
Measure 3D objects
1 Click a 3D model in a PDF to enable it.
2 Click the 3D Measurement Tool icon on the 3D toolbar. (If the 3D toolbar view is set for consolidated tools,
select the 3D Measurement tool from the pop-up menu next to the Navigation tool.)
3 Select the options you want in the Snap Enables and Measurement Types areas of the 3D Measurement Tool palette.
4 Right-click the model background, and change the options as needed. Leave the 3D Measurement Tool palette open.
5 Measure the 3D model:
• To measure the distance between two positions on the 3D model, click to set a start point. Then move the pointer
to another location or an edge.
• To measure the circumference of a round shape, move the pointer to the edge of the shape so that a circle appears,
and click once.
• To create and set an annotation on the measurement, right-click the object background and select Change
Markup Label. Type a markup label. Measure the 3D model as described previously. Click to set the end point
for the measurement, and then click a third time to set the location of the measurement and label.
• To save a measurement as a comment, select the Hand tool, right-click the measurement, and click Convert To
Comment.
• To discontinue a measurement, right-click and choose Cancel Measurement.
• To delete a measurement markup, click it with the3D Measurement Tool and press Delete.
Note: To learn how to rotate, pan, zoom, and snap while you measure, right-click the model and choose 3D
