Welcome to my profile. I am Erol Alkaya, the Founder and Lead Industrial Designer of Helix Design Studio. With extensive experience in mechanical engineering and product development, I bridge the critical gap between conceptual ideas and the actual production floor. I don't just draw 3D shapes; I engineer functional, production-ready parametric solids. Whether you are an inventor looking to prototype a new consumer product, or a manufacturer needing high-precision reverse engineering from 3D scan data, I provide solutions built on strict Design for Manufacturing (DFM) principles. I approach every project with a toolmaker's perspective. My Core Expertise Includes: High-Precision Reverse Engineering (Scan-to-CAD): Expert-level workflow using Geomagic Design X and SolidWorks to convert dense STL/OBJ scan data into clean, fully editable parametric models. I provide 3D deviation analysis (heat maps) to guarantee dimensional accuracy. Plastic Injection Molding & DFM: Deep knowledge of tooling requirements, including draft angles, uniform wall thickness, sink mark prevention, undercut resolution, and mechanical assembly features (snap-fits, screw bosses). 3D Printing & Prototyping Optimization: Engineering complex, multi-part assemblies, interlocking joints, and smart sectioning for FDM, SLA, and SLS additive manufacturing. Professional Deliverables: Supplying native, feature-based SolidWorks assemblies, watertight neutral formats (STEP, IGES), and comprehensive 2D technical production drawings. When you collaborate with Helix Design Studio, you are partnering with an engineer who ensures your product is designed to fit, function, and manufacture flawlessly without costly downstream errors. Let’s discuss your project and bring your engineering data to life.

Mechanical Engineer | Fusion 360 Expert | Product Design & Manufacturing-Ready CAD I am a **Mechanical Engineer specializing in Autodesk Fusion 360**, focused on turning ideas, sketches, existing parts, and technical requirements into **accurate, functional, and manufacturing-ready CAD designs**. My goal is not simply to create a 3D model that looks good on screen. I design with **real-world functionality, manufacturability, assembly, tolerances, materials, production methods, and future design changes** in mind. Whether you need a single mechanical component, a complete assembly, a prototype-ready product, production drawings, or an existing design improved for manufacturing, I can take your project from **concept to production-ready CAD**. I work extensively with the **native professional capabilities of Autodesk Fusion 360**, creating clean, editable, fully parametric designs without relying on third-party plug-ins or add-ins. This makes project files easier to transfer, modify, maintain, and continue developing after delivery. What I Can Do for You Mechanical Design & Product Development * Mechanical component and product design * Concept development and design refinement * Functional mechanism design * Design of mechanical assemblies * Parametric and feature-based CAD modeling * Design optimization * Product improvement and redesign * Prototype development * Design for Manufacturing (DFM) * Design for Assembly (DFA) 3D CAD Modeling * Precise parametric 3D models * Complex mechanical parts * Multi-component assemblies * Solid modeling * Surface and freeform modeling * Mesh and STL modification * Existing CAD model modification * 2D drawing to 3D CAD conversion * Sketch, image, or concept to 3D model * STEP / STP / STL / DXF and other manufacturing file preparation Mechanical Assemblies * Multi-part assemblies * Component relationships and joints * Motion-oriented mechanism design * Interference and fit checking * Exploded assemblies * Assembly organization * Design revisions and component replacement * Production-ready assembly documentation Manufacturing-Ready Design I design parts with the manufacturing process in mind rather than treating manufacturing as an afterthought. Projects can be prepared for: * CNC machining * 3D printing * Sheet metal fabrication * Laser cutting * Waterjet cutting * Plasma cutting * Conventional machining * Prototype manufacturing * General mechanical fabrication Sheet Metal Design * Sheet metal components * Flanges and bends * Folded enclosures and brackets * Flat patterns * Manufacturing-ready DXF files * Bend-aware design * Production drawings Engineering Drawings & Documentation * Professional 2D engineering drawings * Manufacturing drawings * Assembly drawings * Dimensioning * Geometric tolerancing where required * Section and detail views * Exploded views * Parts lists / BOM-ready documentation * Production notes * PDF and DWG/DXF drawing output Reverse Engineering & CAD Reconstruction If you already have a physical component, STL/mesh, old drawing, image, or incomplete CAD file, I can recreate it as a **clean and editable parametric Fusion 360 model**. This includes: * Existing part reconstruction * STL / mesh to editable CAD * Legacy drawing to modern 3D CAD * Measurement-based modeling * Replacement part modeling * Design modification and improvement Design for 3D Printing * FDM-friendly mechanical parts * Prototype components * Functional printed assemblies * STL preparation * Clearance and tolerance consideration * Print-oriented geometry optimization * Support-conscious design * Rapid-prototyping models CNC & CAM Preparation For suitable projects, I can support the transition from CAD into Fusion 360's integrated manufacturing workflow, including machining-oriented model preparation and CAM-ready geometry. Rendering & Product Presentation When needed, I can also create: * Professional product renders * Material and appearance setups * Exploded product presentations * Technical visualizations * Product concept images * Assembly animations and motion presentations Why Work With Me? Engineering First — Not Just CAD Modeling A CAD model should not only look correct. It should also make sense mechanically. I approach every project from a **mechanical engineering perspective**, considering: * Function * Geometry * Manufacturability * Assembly * Mechanical clearances * Design intent * Material usage * Production constraints * Maintainability * Future revisions Fully Parametric & Editable Models Whenever appropriate, models are built with a clean parametric structure so dimensions and design features can be modified efficiently instead of rebuilding the entire part. Manufacturing-Oriented Workflow I aim to identify potential production problems before they become expensive manufacturing problems. The objective is always to provide a design that is as close as
