Solid Modeling

Pro/ENGINEER Wildfire 3.0 allows you to easily create 3D solid models, enabling you to visualize parts and assemblies with a realistic appearance.  Based on material properties such as density, these models have mass, volume, surface area and other physical properties such as a center of gravity. 

For example, consider the cast aluminum engine block shown below.  This model was created in millimeters, and has the mass properties shown.  The coordinate system labeled 123 indicates the center of gravity of the model.

The following are advantages of solid modeling:

• If the model changes (such as increasing the number of cooling fins), all of the mass properties would automatically update.
• Solid models also allow you to check tolerances and clearance/interference between components in an assembly.

VOLUME = 3.332e+04 MM^3 SURFACE AREA = 2.488e+04 MM^2 DENSITY = 2.7e-06 KG/MM^3 MASS = 8.998e-02 KG CENTER OF GRAVITY X = -0.642 MM Y = 20.508 MM Z = 24.194 MM Solid Model and its Mass Properties
