SolidWorks & CAD/CAM Expert | 14+ Years | Sheet Metal & DFM Specialist Hi, I'm Abu Shahama Khan, founder of Arrant Engineering Solutions. I do two things: design manufacturing-ready mechanical products that don't fail on the shop floor, and build SolidWorks automation tools (C# add-ins, VBA macros) for engineering teams losing hours to repetitive CAD work. Track record: - Top 30 SolidWorks freelancer on Freelancer.com - 300+ clients across 50+ countries, 14+ years - 4.8/5 rating across 205+ reviews - 99% on-budget delivery, 87% on-time delivery - Preferred Freelancer, ASME Y14.5 GD&T Certified - Largest assembly delivered: 8,759 components Mechanical design work I've led (NDA-anonymized where required): - Multi-thousand-component sheet metal chassis for an acoustic recording studio (European client) — equation-driven parametric design that cut studio resize iterations from ~1 week to ~10 minutes - 20–30 m parametric maritime observation tower (German client) — DNV/ABS/IMO compliance, FEA validation coordinated through specialist third party - Multi-bay IoT parcel locker (USA) — lock-agnostic enclosure designed to accept UL 294-certified electronic lock modules from multiple manufacturers, IP54 ingress protection - IP65 outdoor display enclosure (Australia) — sheet metal + thermal management - FDA-regulated medical laser device (Canadian medical technology client, under NDA) — ISO 13485 design controls - Heavy industrial weldments and lifters, food-grade NSF/ANSI equipment, patent drawings for EU/UK/USA/China filings SolidWorks automation work: - Custom add-ins (C# / SolidWorks API) — drawing standard validators, BOM generators, custom property managers, EPDM workflow integrations - VBA macros for batch PDF/DXF/STEP exports, file rename utilities, and Pack-and-Go automation - Excel ↔ SolidWorks bridges for parameter tables and BOM round-tripping Stack: SolidWorks (advanced) • CATIA • NX • Creo • Inventor • AutoCAD - ANSYS (FEA/CFD) • KeyShot • C# / SolidWorks API • Visual Studio 2022 - 3D printing (FDM/SLS) Standards & compliance: ASME Y14.5 • ISO 9001 • ISO 13485 • FDA • UL/CE - DNV/ABS/IMO • IP54/IP65/IP67 • NSF/ANSI • DIN Why clients hire me: - Production-ready deliverables — manufacturing drawings, GD&T, flat patterns, BOMs that go straight to the shop floor - Manufacturing-aware design — I know what bend radii, weld preps, and tolerance schemes the fab line will accept - Direct communication with the engineer doing the work — no agency handoff chains - Comfort with regulated and complex projects — medical, maritime, industrial, IoT Based in India (IST). Working hours overlap with US-East 7–10 PM IST and EU 1–6 PM IST daily, with scheduled calls available for US-West and Australia. Send me your project — sketches, STEP files, or a description of the CAD bottleneck. I'll review and flag DFM or workflow risks upfront before you commit.

Sheet Metal Design for Vehicle Parts

Abu did an outstanding job on our vehicle parts project. He designed multiple truck bumpers and converted solid parts into accurate, foldable sheet metal components in SolidWorks, with clean file organization and clear assembly drawings. His technical skills, professionalism, and respect for proprietary designs were impressive throughout. Highly recommended — we're excited to continue working with him!

Procurement

Abu has helped us with 2 projects where we needed CAD drawings of new/special products. Both projects were executed swiftly at the agreed price, and to our full satisfaction. Abu is responding fast and is excellent at transforming written descriptions in combination with hand drawings to proper CAD files. I highly recommend Abu to anyone looking for a similar service.
