Are you looking for a CAD designer who truly understands how a part is manufactured? Too many CAD files are rejected by CNC machines because they are drawn by designers who don't know the reality of the factory floor. My expertise lies exactly there: I bridge the gap between your concept and the production machine. Working daily in an industrial environment, I have a deep mastery of production workflows and CAD/CAM software (Lantek, DraftSight, QCAD, FreeCAD). I know that a plan isn't just a drawing—it's a precision tool that must be flawless. What I bring to your project: Precision Conversion: Transforming PDFs, sketches, or photos into 100% usable DXF/STEP files. DXF Optimization: Complete cleaning (removing duplicates, closing contours, 1:1 scaling) to prevent machine errors and reduce cutting time. Industrial Drafting: Creating dimensioned PDF plans according to ISO standards, with professional title blocks and ISO views for total clarity in the workshop. Design for Manufacturing (DfM): Taking real-world constraints into account (material thickness, tool diameters, bend tolerances). Why collaborate with me? Responsiveness & Reliability: Based in Belgium, I react quickly and strictly respect your deadlines. "Workshop-Ready" Quality: My files are tested and ready for direct import into your nesting software (Alma, Lantek, etc.). Verified Professionalism: My rigor and identity are guaranteed by the platform. My goal is simple: to provide you with technical documents so clear that your machine operator won't have a single question to ask. Ready to launch your production? Contact me now to discuss your project! Expert en conception industrielle avec une expérience concrète en atelier de fabrication. ​Vous cherchez un dessinateur qui comprend réellement comment une pièce est fabriquée ? ​Trop de fichiers CAO sont rejetés par les machines parce qu'ils sont dessinés par des graphistes qui ne connaissent pas la réalité de l'usine.
