Growing up in an advanced mult-axis CNC machine shop and furthering my experience with studies in International Industrial Product Design Marketing and Mechanical Engineering I bring 25 years of theory and deep experience in the hands on / real world aspects of how precision industrial, medical, food processing, commercial, aerospace and consumer product products are conceptualized, prototyped and later produced and sourced. I have substantial experience in multi-axis CNC programming for high-speed, horizontal and vertical milling centers as well as multi-axis Swiss lathes (Citizen) via Mastercam. I am very well versed in a variety of materials and have years experience programming complex, multi-surfaced components to simple components, for short run prototypes, high speed, long run production and high-confidence lights out operations. In addition I have many years experience in CAD modeling and design via Solidworks 2018 including part, assembly and prints of which I also own one seat of latest 2018 version including Solid Works Simulation and the new, very impressive Solid Works Visualize. With Visualize I have the ability to not only design full solid models and assemblies but also create incredible, rendered real world pictures and images. I have designed, prototyped, sourced and brought to market several products from the ground up in various market segments including industrial, medical, food processing and aerospace. (including sheet metal, injection molded parts and of course precision machined parts with very tight tolerances). I currently own a Okuma MB-4000H Multi-Axis Horizontal Milling Center in which I can complete advanced protoypes to high speed, long run production runs. I am very confident that my education, real world experience and upbringing in a CNC environment has given me the ability to not only boldly design and or program components and products with disruptive, world class mechanical characteristics, it has given me the hands on experience to also design within the mindset of key variables like machine-ability and optimal material selection as this directly relates to final product cost. I have deep experience in optimization of solid model product design for machining and injection molding as well. I also hold several patents within the industrial and packaging spaces. I welcome any inquiry, as someone that truly enjoys this innovative space, I take projects with the assumption as if they were my own products. I embrace deep communication and work with the latest versions of all software I am versed in, with a deep emphasis on leveraging the amazing digital world we live in. I am willing to negotiate hourly rate based on the project.

1-Mostly, I drew the Aluminum injection molds, separated the mold, what the mold elements would be and I could create the technical drawings of the mold elements for production. First of all, I make all the controls of the 3d data you have according to the technical drawing, if it is a drawing that cannot be removed from the mold, we create the molding process, then I create the female mold and remove the separation line and make it male in the 3d environment. I take out the technical drawing of each element of the mold separately and file it. If desired, I offer the opportunity to make a presentation with a 3d pdf file. Injection Molding is serious business. Correct design of the mold is very important for the mold to have a long life and to work efficiently. If you want to work with an experienced and reliable person, I am ready to make an offer. 2-When you have an idea as a prototype, I can work together to help you draw the product you want in 3d. I have been designing metal injection molds by actively using Solidworks program for more than 15 years. Afterwards, I have been designing machinery for more than 3 years in a company that produces mining and concrete pumping machines. Reading Technical Drawing Part drawing and 3D Modeling specialist. I am proficient in creating cut lists for laser and plasma, and designing sheet metal or surface parts. I can prepare technical documents to manage the production, explain to the welder and CNC operator and have them manufactured, and work in accordance with teamwork. I specialize in surface modeling and solid modeling for product design to create a photorealistic (Render) view of the product. I can also work competently in modeling and animating any mechanism. I can also help you realize a design that can be produced with 3d printing. I am proficient in machining and chipless manufacturing processes.

Message me before posting your job — I typically reply within 2 hours with a scoped estimate. Most CAD freelancers draw shapes. I engineer functional, manufacturable systems built for the factory floor. I'm a Mechanical Engineer (NIT Andhra Pradesh, B.Tech 2026) and the founder of Aerora Dynamics, an industrial UAV startup building heavy-payload drones. I lead end-to-end mechanical design for autonomous multi-rotor aircraft: weight budgets, aerodynamic clearances, structural stress conditions, and Design-for-Manufacturing from day one — not CAD models that look good but can't be built. Recent proof of work: I took a hexacopter chassis (25 kg MTOW, 10 kg payload capacity) from a SolidWorks parametric assembly through FEA validation to CNC-aluminum prototype coordination. The arm-to-socket junction was redesigned twice against simulation data before reaching a 1.78x safety factor at rated load. That's the standard I hold every project to.

I don’t approach projects as isolated design tasks. I approach them as systems that must survive prototyping, manufacturing, assembly, cost pressure, and real-world use. 📐 What You Can Expect Working With Me: - Clear, structured CAD suitable for iteration and production - Design decisions informed by manufacturing reality - Practical communication with engineers, suppliers, and manufacturers - Honest feasibility feedback (go / no-go when needed) - Designs meant to be tested, not just rendered 📐 Core Capabilities: - 3D CAD modeling (Siemens NX) - 2D technical drawings (AutoCAD Professional) - CNC, laser cutting, and sheet metal preparation - Injection molding–ready part design - Fixture, bracket, and assembly design - BOM creation and production planning support - Reverse engineering and scan-based modeling 📐 Injection Mold & Manufacturing Experience I have hands-on experience designing plastic injection molds and mold-ready parts, including projects for automotive and food-related products. ⚙️ I’m familiar with: - Injection molding–ready design, Core / cavity logic - Draft angles & wall thickness optimization - Parting lines and shut-off surfaces - Shrinkage and material behavior - Gate concepts (hot runner, valve gate) - Collaboration with mold makers and CNC shops - Design for Assembly (DFA), production validation - Engineering-driven product development - Long-term product roadmap support My focus is always on tool longevity, cycle time, surface quality, and cost efficiency. 📏 Typical Projects I Work On: - Automotive accessories and aftermarket products - Mechanically complex plastic or metal parts - Prototyping-heavy product development - Production validation before tooling - Redesigns for cost reduction or manufacturability - CAD clean-up and production conversion 📌 Primary CAD Tool: Siemens NX, AutoCAD and Geomagic Design X I work primarily in Siemens NX, which is widely used in high-end automotive and industrial manufacturing. I can deliver clean, fully editable STEP / STL / Parasolid files, and I regularly convert and work with SolidWorks, Fusion 360, Rhino, SketchUp, and scan-based data. If you use SolidWorks or another CAD system, this is not a limitation — deliverables are always production-ready and compatible. 📌 If you need more than a modeler—someone who understands how products are actually built and scaled—I can support your project from concept to production readiness.
