What is Pro/Engineer?
3D solid modeling and design program
Fundamental pro E concepts:
Feature-based modeling
Associative
Parametric
What does feature-based mean?
Feature-based modeling means you start with simple basic features and then add more features
Part is ‘constructed’ so that its individual features describe the way the geometry should behave - i.e. a cut ‘knows’ its shape and location and the fact it has negative volume
Parametric Design
Each feature you give the part is a parameter which can be changed
Parent-child relations are important to understand
Implicit vs. Explicit Relationships
Implicit - new geometry or feature is sketched/dimensioned based on some existing part
Explicit - new geometry is defined mathematically by the user, i.e. any number of spoke holes in a bike rim are all equally distant to each other
What is parametric modeling used for?
CAD
Analysis of design concepts
Improvement of rapid prototyping process
Reduced iterations and increased optimization
Simulation
Actual performance of design
FEA (finite element analysis)
Simulated performance under extreme conditions safely - fire, earthquake, max. loads
Where is Pro E available from?
Student version is available from ptc website or bookstore, etc.
Student version also available in EBUII 239 and 203 computer labs
Note- student version and full version incompatible!
