Many different tools are available for easy modeling : draw, grab, smooth, flatten, paint, symmetry, ...
Dare anything thanks to the undo-redo and the standard ".obj" save format. Zoom and pan with two fingers.
Imagine something, sculpt it, and share with others.
You'll enjoy this simplified tactile modeling experience inspired by the sculpture mode of Blender and ZBrush. Look at them if you want to get more serious.
Last but not least, this sofware is free, open source, and without any annoying ad ! If you want to improve it, feel free to join the project.
