Active Dimensions 3 is a very easy-to-use CAD and 3D modeling application with several special features. It has thirty-one preset surfaces which are categorized as extruded regular polygons, inverse kinematics capable joints, platonic solids, 3D primitives, and rounded cubes, cylinders and diamonds. Other features include Boolean operations, basic inverse kinematics, interactive light positioning, polygon painting and real-time manipulation. You can save your image as a bitmap or export your work in the DXF, VRML 2, or Wavefront Obj format. Active Dimensions 3 also features a special 3D positioning control, called the Dynamic Transformation Control, which greatly facilitates 3D positioning.
