Model3D was designed from first principles to be easy to learn and use. Simple functions give the user the power to create nearly anything without a steep learning curve.
Camera areas near the edges of the screen make moving around intuitive, "ghost" controls and camera focus allows you to concentrate on a single element in a complex scene.
Functionality allows you to easily create new faces and align vertices in order to create complex shapes. Simple, low-level functions combined give lots of creative power while still being easy to learn.
Model3D is a direct (and destructive) modeler, allowing you complete control over the geometry you're creating. Don't worry about complex operations, just model.
Sometimes it's easier to begin a shape in 2D. Model3D allows you to draw on a 2D grid and then extrude or rotate that 2D shape into 3 dimensions. Powerful, yet easy to use.
