Frequently Asked Questions
What is the main difference between Catia and Parasolid?
Catia is a complete CAD/CAE/PLM application for design, simulation and analysis, while Parasolid is a geometric modeling kernel that serves as the underlying engine for many CAD products, providing high‑precision geometry services.
Can I use Parasolid directly without a UI?
Parasolid itself has no graphical user interface; it is a library you embed into your own application or use within another CAD system that provides the UI.
Is Catia the most expensive CAD suite?
Catia is among the more costly premium CAD suites due to its extensive feature set and professional licensing, but costs vary by modules, term and contract terms.
Which is better for research on surface modeling?
Parasolid offers the most mathematically precise NURBS and surface capabilities for research, while Catia provides a rich environment for applied surface modeling within a full design workflow.
