The main idea – to use drawing instead of the usual methods of modeling. You just make strokes in 3D space, or lines, whatever. 3D Brush may consist of several objects and change their color and deformation, depending on the graphic tablet pen pressure. Each brush can have a different set of parameters, it’s easily selected by the user as a modifier stack. A result it turns library of different sets of brushes which users can exchange. Two different stroke – the two different from each other objects.
In addition there are tools for sculpting (including Remesh), and unusual tool for a very quick drawing of surfaces of revolution.
PolyBrush
All the files created with this tool are said to be supported by most 3D editors.
