Generative Drafting (CATIA)
CATIA's 2D drawing workbench — views, dimensions, tolerances, and annotations generated from the 3D model.
Definition
Drafting creates a CATDrawing from a CATPart or CATProduct. Views (front, projected, section, detail, broken, isometric), generative dimensioning (extracts dimensions from the 3D model), tolerancing (GD&T per ASME Y14.5 / ISO 1101), title blocks, and BOMs are all generated and link back to the source 3D.
Why it matters
Drawings are still the manufacturing deliverable. CATIA's Generative Drafting produces them with associativity — change the 3D model, the drawing updates.
Common pitfalls
- Manual dimensions that don't link back to model parameters — diverge silently.
- Title block inconsistencies across drawings — sheet sets look ad hoc.
- Not setting drawing standard (ANSI vs. ISO vs. JIS) — dimensioning style is wrong.
This concept is a core structural element of the CATIA drafting and engineering environment developed by Dassault Systèmes. Dassault Systèmes' high-end PLM-grade CAD — the production tool of aerospace, automotive, and class-A surface modelling.
Relevant CATIA FAQs
❓ What's the difference between CATIA and SOLIDWORKS, both Dassault products?
Different markets. SOLIDWORKS is mid-market mechanical CAD (industrial machinery, consumer products). CATIA is high-end (aerospace, automotive, very large assemblies, class-A surfacing). CATIA's learning curve, price, and capability are substantially higher.
❓ Is CATIA available for individual hobbyists?
No. CATIA is sold through VARs to enterprises and educational institutions. Hobbyists looking for similar capability use Rhino (surfacing), Plasticity (modern direct modelling), Onshape (cloud), or older perpetual versions of SOLIDWORKS via student licenses.
❓ What is the difference between V5 and V6?
V5 is the file-based desktop platform (still widely used). V6 was the predecessor to 3DEXPERIENCE — server-stored on ENOVIA V6. CATIA on 3DEXPERIENCE is the current 'V6'-equivalent track. Many organisations run both V5 and 3DX in parallel.
