Use CAD import to enhance the representation of objects:

The 20-sim 3D Mechanics Toolbox provides you with the tool that
makes 3D dynamic modeling easier, the 3D Mechanics editor.
Bodies
You can create 3D models by dragging bodies in a 3D workspace.
The representations of each body can be changed to a sphere, block,
cylinder etc. Furthermore, colors can be changed and descriptions
can be added. The size and shape of a body are merely for representation,
a body is fully characterized by its inertia coefficients and
mass.

Joints
Bodies are interconnected by the use of joints. Several joints
are present in the library, divided in two groups, rotational
joints and translational joints. These joints can also be drag
and dropped on the workspace. Constraints can be added to create
closed loop systems like four bar mechanisms or stewart platforms.
Interface
The user interface has 4 different modes in which you can select,
connect, translate and rotate bodies and joints. Much effort is
done to keep the graphical user interface as natural as possible.
Multiple views are supported. Besides the 3D environment, you
can see 2D intersections in the xy xz, and yz plane.
Models
The 3D Mechanics Editor can generate a 20-sim model from your
3D model. This 20-sim model comprises all dynamics and kinematics
of the model. Forces can be applied to the joints or on to each
body directly. You can also couple springs and dampers from the
mechanics library in 20-sim, to the joints, because the whole
model is port-based. Gravity can be set as an external force.
Eventually, the dynamic response of the complete model can be
shown by the 3D Animation toolbox.
