Need a clean, production-ready 3D model from a drawing, sketch, or a set of dimensions? I turn 2D drawings, hand sketches, and technical specs into accurate, parametric 3D models delivered as STEP, STL, or DXF — ready for CNC, 3D printing, or manufacturing. I'm a mechanical CAD specialist focused on parametric modeling. That means your part isn't just "drawn" — it's built on a logic of dimensions and constraints, so revisions are fast and every measurement is exact. If you need one part or a whole family of variants, I can produce them quickly and consistently. What I do for you: - 3D modeling from 2D drawings, sketches, photos, or written specs - Mechanical parts: brackets, enclosures, fixtures, adapters, mounts, gears, housings - Parametric models — easy to revise, scale, or generate in variants - Clean exports: STEP (master), STL (3D printing), DXF (2D) - Design for manufacturing: tolerances, wall thickness, print/CNC-friendly geometry How I work: I start by turning your request into a clear technical spec, so we're aligned on dimensions, tolerances, materials, and deliverables before modeling begins. You get exactly what you asked for — no guesswork, no endless revisions. Tools: CadQuery (parametric), FreeCAD, SolidWorks, with STEP/STL/IGES/DXF output. If you have a drawing or an idea and need it modeled right, send me a message with your files and I'll tell you exactly how I'd approach it. With 6 years modelling mechanical parts.

Hello, I'm Filipe Fernandes, an accomplished embeded and PCB designer with a proven track record spanning over two decades. My expertise is in electronic embeded design, PCB design, and RF noise management. Armed with a diverse skill set and state-of-the-art testing equipment, I excel in unraveling complex challenges and delivering ingenious solutions. During my career journey, I've had the privilege of working with dynamic team of professionals, consistently steering toward our shared objectives. My passion for innovation led me to harness the power of freeCAD, allowing me to design and 3D print prototype enclosures with precision and creativity. My journey began at Red River College, where I pursued a two-year program in Electronic Engineering Technology, followed by Computer Engineering Technology. My role as an in-house EMC expert at Vansco marked a pivotal moment that laid the foundation for my consultancy, Tagus Consulting. Two standout projects reflect the depth of my expertise: 1. I designed a microcontroller-based product for MRI rooms, situated in close proximity to the magnetic bore, ensuring uninterrupted functionality during imaging—still in use after 17 years. 2. A plastic enclosure challenge: Enhancing a tractor control unit's EMC performance from 15V/m to 145V/m while maintaining plastic materials and unchanged connector locations. Outside of my professional endeavors, I cherish quality time with my family, exploring the scenic parks of Manitoba. .

I am an individual with an academic background in Geophysical Engineering and professional experience in Entry Data Processing within the logistics industry. The combination of a science-based education and practical work experience has shaped me into someone who is detail-oriented, analytical, and capable of managing information in a systematic and structured manner. During my time working in Entry Data Processing, I was responsible for entering, verifying, and maintaining operational data related to shipments, goods receipt, warehousing, and distribution activities. This role required a high level of accuracy, speed in data entry, and consistency to ensure that the information could be relied upon for operational and strategic decision-making. I became proficient in using tools such as Microsoft Excel, ERP systems, and internal company databases, while also coordinating with warehouse, transportation, and administrative teams to ensure that the data reflected actual field conditions. This experience strengthened my skills in information management, data processing, and cross-departmental communication. I am accustomed to working under pressure and meeting strict deadlines, which has instilled discipline and strong time management in my professional approach. Academically, my studies in Geophysical Engineering provided me with a solid foundation in scientific data analysis, problem-solving, and the application of technology to understand complex natural phenomena. This background trained me to think critically, logically, and with attention to detail—skills that I have successfully transferred into my professional work. As a result, I am not only capable of accurate data entry but also of identifying patterns, analyzing information, and offering insights that contribute to operational efficiency. The combination of practical experience and academic training makes me an individual who is adaptable to new technologies, meticulous in handling information, and able to contribute meaningfully to improving company operations. I believe that my ability to bridge technical and administrative aspects provides significant added value, both in supporting smooth logistics processes and in enhancing the company’s information systems. - Know ArcGIS, Geosoft Oasis Montaj, FreeCAD, Blender, ERP Dynamics - Full project management from start to finish - Good communication, hard work, and good team
