MoI’s sleek intuitive UI blends a fluid easy workflow with powerful tools, making it the perfect choice for someone who has been frustrated with the complexity of existing CAD tools.



Rhinoceros is described as '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' and is a 3D Modeler in the photos & graphics category. There are more than 50 alternatives to Rhinoceros for a variety of platforms, including Windows, Mac, Linux, Web-based and iPad apps. The best Rhinoceros alternative is Blender, which is both free and Open Source. Other great apps like Rhinoceros are FreeCAD, SketchUp, SOLIDWORKS and Autodesk 3ds Max.

MoI uses the same 3dm file as rhino and NURBS design. The UI is easier to navigate so you do not have to spend ages looking for the right command, moreover it can be easily customized. You can add shortcuts and run scripts if you need additional features and use the forum to get any help you might need. I used rhino since version 2.0 but prefer Moi because is more design focused. It does not have an internal render engine, but there are plenty available nowadays.
