User Guide
Measuring preferences
Change the 3D Measuring preferences to determine how 3D data is measured. These options appear in the
Measuring (3D) panel of the Preferences dialog box.
Use Scales And Units From Model (When Present) Displays measurements based on the model units, if present,
generated from the original 3D model. Deselect this option to specify the units of measurements manually. This
setting can be changed in the 3D Measurement Tool palette.
Use Default Display Unit Uses units of measurement that you specify here rather than those in the 3D model.
Significant Digits To Display Specifies the maximum number of digits in the measurement number.
3D Measuring Line Color Specifies the color of the line that appears when you click or drag to measure an object.
Measure Feedback Size Sets the text size for the measurement display.
Angular Measurements Shown In Specifies units as either degrees or radians.
Circular Measurements Shown As Designates whether the diameter or radius is measured for circular parts.
3D Snap Settings Turns on snap and specifies whether points, arcs, edges, silhouette edges, or faces are snapped to.
Sensitivity indicates how close the pointer needs to be to the item being snapped to. For Snap Hint Color, specify the
color of the snap line that appears when you hold the pointer over the 3D object.
Set 3D views
The default view of a 3D model lets you quickly revert to a starting point at any time as you interact with the model.
A default view is different from a preview, which determines what the 3D model looks like when it’s not activated.
The list of all available views for the 3D model appears in the Views menu on the 3D toolbar and in the View pane
of the Model Tree.
You can also create additional views of the 3D model in Acrobat that let you quickly navigate the 3D content as you
want (such as top, bottom, left, right, inside, outside, exploded, or assembled). A view can include lighting, camera
position, rendering mode, the Model Tree state, and transparency and cross section settings. When you add a
comment or markup to the 3D model, Acrobat automatically creates a view.
You can link views to bookmarks in the Bookmarks panel, or you can use the Go To 3D View action to link views to
buttons and links that you create on the page.
