Chapter 4: Analyzing product designs The tools on the Design Review toolbar and in the Tools menu facilitate design-review work. Calculations for analysis can be precise, based on exact geometry defined by the original CAD file. Or, calculations can be approximate, based on the level of detail set for the display.
Bounding boxes A bounding box is a rectangular wireframe entity that encloses the selected components. The active coordinates system (Main CS) determines the orientation of the bounding box faces. Each segment of a bounding box is also an entity. Bounding boxes are calculated from geometric elements. You can make bounding boxes of a part, multiple parts, assemblies, or subassemblies. Bounding boxes appear under the Models branch of the Model Tree structure. You can hide or show bounding boxes or individual segments, as needed. You can also rename them. Each segment of a bounding box is an entity. Adobe 3D Reviewer gives default names to the bounding boxes and segments. You can change the names in the Model Tree after you create the bounding box.

Create a bounding box entity 1 Choose Tools > Bounding Box. 2 Select options for displaying units with the bounding box wireframe:
• Choose the measurement system in the Unit menu. • Select Display Unit to display the units of measurements with the dimensions, or deselect it to see the dimension values alone. Note: The unit options apply only to bounding boxes created with the middle button, Create Bounding Box With Dimension. 3 Select the parts or assemblies that you want to enclose in the bounding box.
The Selection area displays the volume and X, Y, and Z dimensions of the bounding box. 4 Click to create bounding boxes:
• Create Bounding Box
, to create a wireframe bounding box.
• Create Bounding Box With Dimension
, to create a wireframe bounding box that displays each dimension
measurement.
• Create Gravity Center
, to create a point entity for the center of gravity of the bounding box.
Each click creates a new bounding box.
