CATIA V5 Drafting Module – Creating Engineering Drawings from 3D Models (Updated June 2026) (Updated June 2026)

You can design the most brilliant 3D part in CATIA, but if you can't produce a clear engineering drawing from it, that part cannot be manufactured. The ability to create correct, fully-dimensioned 2D drawings from 3D models is one of the most consistently tested skills in mechanical engineering interviews at Bajaj Auto, Tata Motors, and Force Motors. With the AURIC zone in Sambhajinagar pulling in Rs. 71,343 crore in manufacturing investment and creating 62,405 engineering jobs at plants like Skoda VW (Plot A-1/1, Shendra) and Bajaj (Plot G-137, Waluj), drafting skills are more in demand than ever — particularly as companies transition from AutoCAD 2D drafting to CATIA 3D-driven drawing generation. Episode 17 of our CATIA Essentials series teaches you the complete CATIA V5 Drafting workflow from creating your first drawing sheet to exporting a print-ready PDF.

Getting Started with CATIA V5 Drafting: Creating a New Drawing Sheet

To open the Drafting workbench in CATIA V5, go to Start, then Mechanical Design, then Drafting. CATIA will ask if you want to create a drawing from an existing 3D part (select Empty Sheet to manually link later, or All Views to auto-generate standard views). Choose your sheet format (A4, A3, A1) and projection angle (first-angle for ISO/Indian standards, third-angle for ASME/US standards). The drawing sheet opens with a standard border and an empty title block at the bottom right. A quick tip: before placing any views, set your drawing standard in Tools, then Options, then Mechanical Design, then Drafting to ensure dimensions, text, and annotations match your company or university format exactly.

Generating Orthographic Views from Your 3D Part

In the CATIA Drafting workbench, go to Insert, then Views, then Projections, then Front View. Click on your 3D part's face in the model viewport to define the projection direction — a preview appears on your drawing sheet. Reposition it by dragging, then click to place. Once the Front View is on the sheet, you can add Projection Views (top, bottom, left, right) by clicking Insert, then Views, then Projections, then Projection View, and clicking the front view as the reference. CATIA automatically maintains the correct orthographic alignment. The isometric view is added from Insert, then Views, then Isometric View. These views are fully associated with the 3D model — update the part geometry and the drawing views refresh when you double-click Update from the sheet toolbar.

Drawing View Type	What It Shows	When to Use
Front View	Primary projection showing most features	Always — first view placed on sheet
Projection View	Top, bottom, left, right orthographic	Show features in other directions
Section View	Cross-sectional cut through the part	Internal bores, walls, and channels
Detail View	Magnified region of existing view	Complex threads and small fillets
Isometric View	3D pictorial representation	Assembly clarity, customer documentation
Auxiliary View	Projection at angle to principal planes	Inclined faces with true-shape dimensions

Section Views and Detail Views: Showing What's Hidden Inside

Section views reveal internal geometry that cannot be seen in standard orthographic projections — critical for hollow parts, internal channels, and threaded bores. In CATIA Drafting, select Insert, then Views, then Sections, then Offset Section View, draw your cutting plane as a 2D line through the front view, and CATIA generates the cross-sectional view with automatic hatching. Detail Views zoom in on a small area of an existing view — insert them with Insert, then Views, then Details, then Detail View, and draw a circle around the feature you want to magnify. Both section and detail views are associative and update when the 3D model changes, making drawing revisions far faster than manual drafting.

Adding Dimensions and Tolerances to Your CATIA Drawing

Adding dimensions in CATIA Drafting starts with the Dimensioning toolbar. Use the Dimensions tool (keyboard shortcut D) and click two points, a line, a circle, or any geometric entity on your view — CATIA measures the exact 3D distance and places the dimension automatically. Tolerances are added by double-clicking the dimension to open the Dimension Properties dialog: set the tolerance type (symmetric, bilateral, limits), enter the values, and CATIA formats the dimension text correctly. The key advantage over manual drafting: dimensions come directly from the 3D model geometry, so there are no manual measurement errors. If you change the 3D feature and update the drawing, the dimension value updates too.

GD&T Annotations, Surface Finish Symbols, and Datum References

GD&T (Geometric Dimensioning and Tolerancing) in CATIA Drafting is handled through the Annotations toolbar. Insert a datum reference by clicking Datum Feature and selecting the surface — CATIA places the datum identifier box (A, B, C). For geometric tolerances, click Geometric Tolerance and choose the symbol (flatness, parallelism, perpendicularity, true position) from the GD&T symbol library. Click to connect it to the toleranced surface and fill in the tolerance value and datum references. Surface finish symbols (Ra roughness values) are inserted similarly from the Annotations, then Roughness Symbol tool. These annotations follow ISO 1101 and ISO 1302 standards, making them directly usable in Indian manufacturing drawings submitted to BIS-compliant workshops.

Title Block, Bill of Materials, and PDF Export for Manufacturing

The title block in CATIA Drafting is editable directly by double-clicking individual text fields — enter part name, drawing number, material, scale, date, and revision level. For company-standard title blocks, create or import a CATIA Drawing Template (.dxf or .CATDrawing) that contains the pre-formatted border and title block, so every new drawing inherits the same format. Bill of Materials (BOM) is generated automatically from assembly drawings using Insert, then Generation, then Bill of Material. To export your final drawing, go to File, then Print to PDF, or use File, then Save As, then DXF to send the drawing to a CNC machine operator or downstream supplier. Bajaj Auto and Mahindra's manufacturing vendors receive CATIA drawings in DXF or PDF format as part of the standard design release package.

Maharashtra's Chief Minister Yuva Karya Prashikshan Yojana (CMYKPY) provides Rs. 6,000-10,000/month stipends for engineering graduates completing on-the-job training at manufacturing companies. CATIA Drafting skills from ABC Trainings prepare students for CMYKPY-eligible design draughtsman roles at Bajaj Auto Waluj, Tata Motors Ranjangaon, Mercedes-Benz R&D Pune, and Force Motors.

FAQs

What is the difference between first-angle and third-angle projection in CATIA Drafting?

First-angle projection (used in India, Europe, and most of Asia) places the front view in the centre, the top view below it, and the right-side view to the left. Third-angle projection (used in the USA and Canada) places the top view above and the right-side view to the right. In CATIA V5, go to Tools, then Options, then Mechanical Design, then Drafting, then View, and select your projection standard. Indian drawing standards (IS 696:2008) follow first-angle projection, so ensure your CATIA training and workplace drawings use this consistently.

Do CATIA drawing dimensions update automatically if I change the 3D model?

Yes — CATIA Drafting views and dimensions are fully associative with the 3D model. When you modify the 3D Part Design geometry and save, the drawing sheet shows yellow update arrows on the affected views. Click the Update toolbar button (or Ctrl+Shift+U) and all views refresh to show the new geometry, with dimension values updating automatically to reflect the changed sizes. This associativity is what makes 3D-driven drafting far faster than maintaining separate 2D drawings — design changes propagate through the drawing automatically instead of requiring manual redimensioning.

Can I create a drawing template in CATIA V5 for company-standard formats?

Yes — CATIA Drawing Templates define the sheet format (size, border, title block) and annotation standards that all new drawings inherit. To create one, set up a blank drawing with your company border and pre-filled title block elements, configure the dimensioning and annotation standards in Tools, then Options, and save the file as a .CATDrawing template. When creating new drawings, point CATIA to this template file. Many Indian automotive companies maintain standardized CATIA templates for A0, A1, A2, A3, and A4 drawing sheets so every engineer on a project produces drawings with identical formatting.

How do I export a CATIA drawing to AutoCAD DWG or DXF format?

In CATIA V5, go to File, then Save As, and select DXF (*.dxf) or DWG (*.dwg) as the file type. CATIA exports the selected drawing sheet as a 2D flat file. Note that GD&T symbols, surface finish annotations, and some CATIA-specific elements may not transfer perfectly due to format differences — always review the exported DXF in AutoCAD or DraftSight before sending to a supplier. For DWG format, ensure your CATIA version supports the DWG release version your recipient's AutoCAD expects (AutoCAD 2018 DWG is the most widely accepted current version).
