CAD applications

Examples of typical CAD applications heavily based on constraints (exploiting variational modeling paradigm) include:

  • Parametric drawing/sketching in 2D
  • 3D sketching and surface design
  • 3D Direct Modeling
  • 3D feature modeling
  • 3D assembly design
  • 3D kinematic analysis and motion simulation
  • Knowledge-based engineering and product optimization
