CAD/CAE Modeling/Analysis 3D & 2D drawing, design & Engineering Experienced in aero/mechanical, electronics, and software specializing in all stages of product development to help you get your project completed, on time, and within budget. With 25+ years of experience as an aerospace engineer, program manager, and systems expert, I deliver high-value solutions in CFD, aeroelastic modeling, CAD design, manufacturing, testing, and proposal development. I’ve supported major programs in defense, aerospace, and advanced manufacturing, and helped startups and government contractors turn complex requirements into executable, cost-effective outcomes. Capabilities range from generating CAD drawings, to fully modeling a product for, to engineering documentation details. helping you write a patent, to taking measurements of an existing product and cranking out a 3D model for you. Can work with you to 3D print your design. Designed, built, and operating own composite 3D printer. Based in the LA/OC area and work in the Aerospace , automotive, machinery, tooling, Biotech consumer products and much more. ___________________________________ ___________________________________ Concept Design: Can produce 3D parametric Models & Annotated General Arrangement drawings to customer specifications and needs. Manufacturing Drawings/Production Drawings: Can produce drawings for use in Additive, Subtractive, and Sheet Bending manufacturing. Assembly Drawings/General Arrangements & BOM's: Can produce a complete & full set of GA's, including all parts lists & Bills of Materials (BOM) which will be required to build the product. 2D CAD to 3D CAD Conversion Service: Can convert individual drawings, or your complete library of 2D CAD drawings into 3D CAD. Paper Drawings to 3D CAD: Can convert your existing stock of paper drawings into full parametric 3D Models and drawings. 3D Printing: Can produce 3D Models for 3D Printing or we can take customer models and convert them for Printing. 3D CAD Animation & Visualization: Can produce 3D Animations & Visualizations of structural and flowfield solutions. Built and tested hardware products for Ground Vibration Testing purposes. Specializing in products and assemblies with part quantities ranging from a few parts to over 1000 parts, from a consumer to industrial application, and from metal, sheet metal, to injection molding manufacturing approaches. Please contact if you want to create new products or modify existing ones. Capable of quickly reverse engineering existing products.
