Rhinoceros (Rhino) is a stand-alone, commercial NURBS-based 3-D modeling tool, developed by Robert McNeel &amp; Associates. The software is commonly used for industrial design, architecture, marine design, jewelry design, automotive design, CAD / CAM, rapid prototyping, reverse engineering as well as the multimedia and graphic design industries.

Rhino can create, edit, analyze, document, render, animate, and translate NURBS* curves, surfaces, and solids, point clouds, and polygon meshes. There are no limits on complexity, degree, or size beyond those of your hardware.

Special features include:

- Uninhibited free-form 3-D modeling tools like those found only in products costing 20 to 50 times more. Model any shape you can imagine.
- Accuracy needed to design, prototype, engineer, analyze, and manufacture anything from an airplane to jewelry.
- Compatibility with all your other design, drafting, CAM, engineering, analysis, rendering, animation, and illustration software.
- Read and repair meshes and extremely challenging IGES files.
- Accessible. So easy to learn and use that you can focus on design and visualization without being distracted by the software.
- Fast, even on an ordinary laptop computer. No special hardware is needed.
- Development platform for hundreds of speciality modeling products. (Windows only)
- Affordable. Ordinary hardware. Short learning curve. Affordable purchase price. No maintenance fees.

CadQuery is an intuitive, easy-to-use python based language for building parametric 3D CAD models. CadQuery is for 3D CAD what jQuery is for javascript. Imagine selecting Faces of a 3d object the same way you select DOM objects with JQuery!

CadQuery has several goals:

    Build models with scripts that are as close as possible to how you&#39;d describe the object to a human.
    Create parametric models that can be very easily customized by end users
    Output high quality CAD formats like STEP and AMF in addition to traditional STL
    Provide a non-proprietary, plain text model format that can be edited and executed with only a web browser

Using CadQuery, you can write short, simple scripts that produce high quality CAD models. It is easy to make many different objects using a single script that can be customized.
