Software That Opens & Edits VDA Files (1 Tools, 2026)

VDA-FS (often saved as .vda) is a neutral 3D CAD data exchange specification defined by the German Association of the Automotive Industry (Verband der Automobilindustrie). Developed specifically to bypass geometric modeling engine discrepancies between CATIA and Siemens NX at the OEM level, VDA-FS is specialized for transferring highly complex mathematical Class-A surface geometry, freeform styling contours, and injection mold parting surfaces without translation errors.

Frequently asked

What is the primary technical limitation of VDA-FS compared to STEP?
VDA-FS is strictly a surface format. It represents geometry as mathematical NURBS curves and faces; it cannot store solid model topology (B-Rep structures), assembly constraints, sheet metal properties, or Product Manufacturing Information (PMI). Supply chains have largely replaced it with STEP AP214 and AP242.
Which industries still maintain active support for VDA-FS files?
The German automotive sector (including Mercedes-Benz, BMW, Audi and their Tier-1 stamping mold suppliers) maintains VDA-FS compatibility inside high-end CAM systems and metrology software to verify stamping die geometries against legacy surface models.
