Convert CATDRAWING to DXF

Recipients using AutoCAD, DraftSight, CAM software, or inspection tools may need an editable 2D file instead of CATIA’s native drawing document. DXF provides a more widely supported exchange format, but it preserves exported drawing content rather than CATIA’s parametric model and drafting intelligence.

What the CATDRAWING format is

.CATDrawing is Dassault Systèmes CATIA’s native 2D drafting format, used mainly with CATIA V5 and related 3DEXPERIENCE workflows. It can contain drawing sheets, generated views, dimensions, annotations, drafting standards, layers, line styles, symbols, and links to referenced .CATPart or .CATProduct files.

Linked model files are needed to update or regenerate views, but a drawing can usually be exported as static 2D content without sending those source models. CATDRAWING files are common in engineering departments, supplier exchanges, manufacturing documentation, and product archives.

What the DXF format is

DXF, or Drawing Exchange Format, is Autodesk’s exchange format for CAD data. It supports 2D entities such as lines, arcs, circles, polylines, text, dimensions, layers, and blocks, plus limited 3D geometry. AutoCAD, DraftSight, BricsCAD, LibreCAD, CAM systems, laser-cutting software, and many inspection applications can import it.

DXF is useful when the recipient needs editable geometry in a non-CATIA application. Select a DXF release supported by the receiving software; older systems may require an older ASCII DXF version. DXF does not retain CATIA feature history, associativity, 3D design intent, or the complete semantics of the original drafting database.

How to convert CATDRAWING to DXF

Using CATIA V5

1. Open the .CATDrawing in CATIA V5. Resolve missing links and update the drawing if the exported views must reflect the current CATPart or CATProduct.
2. Review each sheet, view, scale, layer, annotation, and drafting standard. Hide construction geometry and remove or exclude sheets that should not be delivered.
3. Use File → Save As and choose DXF as the output type. Depending on the CATIA release, DXF may be exposed through the available export command rather than the same dialog.
4. Set the available export options, including DXF release, sheet selection, units, layer mapping, and text or annotation handling. Preserve a 1:1 scale for manufacturing, cutting, or inspection workflows.
5. Save to a new filename such as drawing_export.dxf. Open the result in the recipient’s CAD application and measure a known dimension to verify scale, units, geometry, layers, text, dimensions, and the drawing origin.

Using 3DEXPERIENCE or a desktop converter

In 3DEXPERIENCE, use the CATIA drafting export function available to the assigned role and license, then select DXF. Menu names, export settings, and supported DXF releases vary by platform release and company configuration.

For batch work, CATIA V5 automation or an approved company process can standardize sheet selection, units, layer mapping, and DXF version. Test it on representative drawings before processing an archive.

CrossManager by Datakit is a desktop alternative that can convert supported CATIA data to exchange formats, including DXF in configurations that support CATDrawing input. Confirm the installed version and license support .CATDrawing specifically; support for .CATPart or .CATProduct does not prove that drawing documents are supported.

Online converters

Online conversion is usually unsuitable for CATDRAWING. Many general services do not support CATIA drawing documents, and services that accept CATIA files may support only parts or products. Do not upload proprietary engineering drawings unless the provider explicitly lists .CATDrawing input, documents which entities it preserves, and satisfies the organization’s security and confidentiality requirements. For sensitive or production-critical files, use CATIA or an approved local converter.

Quality and compatibility limitations

• Static 2D output: DXF normally contains exported drawing geometry, not CATIA’s parametric features, model links, constraints, drafting standards, or 3D model.
• Linked views: A missing, outdated, or unresolved source model can produce incomplete or stale generated views. Update the drawing before export when current geometry is required.
• Text and symbols: CATIA fonts, symbols, weld marks, tolerances, and specialized annotations may become substitute text, blocks, or linework. Inspect critical annotations after import.
• Dimensions: The target application may import dimensions as editable dimension objects or as separate lines and text. Confirm the result before using DXF for downstream editing.
• Units and scale: Unit interpretation varies between CAD systems. Check the CATIA drawing units and measure a known feature after import rather than relying on the displayed sheet size.
• Manufacturing data: DXF may omit GD&T semantics, material information, parametric constraints, and other CATIA-specific data. If the recipient needs the 3D model, export a separate neutral format such as STEP.
