Cubes

Not only can polygon meshes be used as a surface or skin for almost any 3D object, but they are also easy to draw on a computer screen, do not take a lot of effort to edit and can be represented as collections of vertices effortlessly.
Cubes is an application that enables you to create monochrome 3D elements that you can convert to polygon mesh objects that you can use for other design projects later on.

Includes a rugged, yet organized and clean interface

The setup is quick and uneventful, especially since it solely entails decompressing the archive. Upon launch, you come face to face with a grid that you can start drawing on right away. You can efficiently increase or decrease the working space so that you can fit your model without too much effort.
Unfortunately, the application lacks in terms of fine-tuning drawing utensils, as all you have at your disposal include a pen, box and cylinder tools at your disposal. The pen is slightly more advanced, as it enables your fill 2D spaces with just a double click.

Allows you to convert your project to mesh or BMP

It is worth mentioning that the utility enables you to analyze your design carefully from all possible angles, an option that can come in handy when you are designing a model with numerous details that you need to pay attention to. In addition, you can double-check your work by using tools such as anaglyph, wires, wire front, light, shadows or colors, for instance.
You can save your project as is or you can export it to various file formats that permit you to open and manipulate the model with other software solutions. Simply put, you can export to 3DS, OBJ, VRML, WRL, OFF, POV or in non-vector formats like BMP and PNG.

A utility that can help you create surface objects

In the eventuality that you prefer to create your custom objects' surfaces or you are working on a design model that entails solid shapes and thin skins, then perhaps Cubes might be the tool to lend you a hand.
