What is 3D Modeling & CAD?
3D Modeling and Computer-Aided Design (CAD) is the technical process of creating precise, geometry specific three-dimensional objects (part files, assembly files) using a software like SolidWorks. These files contain all of the measurements, geometries, materials, tolerances and more that help engineers manufacture parts, products and assemblies. In addition to the 3D models, 2D Drawings and Bills of Materials can be created that help develop a more clear picture of how much a product, part or assembly would cost to produce? It can also help with 3D renderings, assembly instructions, and much more.
Every great product begins as a concept, but moving from an idea to a 3D model or physical prototype is a challenging task. We specialize in transforming your early-stage ideas into fully-realized 3D models optimized for form, fit, and function. Whether you are refining a mechanism or visualizing a new invention, our Twin Cities-based 3D modeling & CAD services provide the foundational CAD data needed for rapid prototyping and design validation. We bridge the gap between idea and concept, giving you the details you need to move your idea forward.

Deciding when your design is ready for formal manufacturing prep
What do I need to provide to start the 3D modeling process?
We can begin with as little as a hand-drawn sketch, a crude physical mockup, or a detailed verbal description. Our Rapid Concept Design service is specifically built to handle early-stage ambiguity. We translate your initial "napkin sketches" into professional SolidWorks CAD data, defining the core measurements and geometries needed to move your idea forward.
Can 3D modeling help determine if my invention is affordable to build?
Absolutely. A primary benefit of early-stage CAD is the ability to generate a preliminary Bill of Materials (BOM) and part volume data. By defining the geometry early, we can provide you with a clearer picture of potential material costs and manufacturing complexity, helping you vet the financial viability of your invention before moving into full-scale development.
How do I show my idea to investors or partners if I don't have a prototype yet?
Beyond technical files, we use your 3D models to create high-fidelity 3D renderings and assembly instructions. These visual tools are essential for presentations, allowing you to show exactly how your invention functions and looks in a real-world environment. This "digital prototype" is often the most effective way to communicate your vision to stakeholders without the lead time of physical manufacturing.
What is the benefit of starting with professional CAD instead of a basic 3D sketch?
Professional SolidWorks CAD is more than just a visual; it is a precise mathematical definition of your product. Unlike basic artistic models, our CAD data includes accurate wall thicknesses, draft angles, and mechanical clearances. Starting with professional-grade models ensures that your concept is actually buildable, preventing costly "re-dos" when you eventually move into manufacturing.
