5. USING CAD MODELS WITH SIMULINK 3D ANIMATION

When working with models of dynamic systems, it is an often requirement to

visualize them in an advanced three-dimensional, preferably virtual reality

environment. As most of the 3D designs in companies are created using some

CAD tools, users need to convert these designs into a form that can be used in

connection with Simulink® or SimMechanics® models and MATLAB®-based

applications.

This section describes how to adapt existing CAD designs for visualization in the

virtual reality environment using Simulink 3D Animation™. The process usually

consists of three steps:

- Exporting VRML models from CAD tools

o Converting part or assembly model into the VRML format used by

the Simulink 3D Animation

- Virtual scene modeling

o Composing the converted model into a virtual scene like urban or

manufacturing environment, adding other objects important for

interaction with the scene – viewpoints, background, lights, etc.

- Linking the virtual scene to a Simulink / SimMechanics / MATLAB

model

o Converting dynamic model quantities represented by Simulink

signals, SimMechanics quantities or MATLAB data objects into

form corresponding to VRML object properties (positions,

rotations, etc.) and establishing a live data connection between

the model and the virtual scene.

5.1. Exporting VRML models from CAD tools

The first part of the conversion process is exporting the CAD model of a part or

whole product assembly from the CAD tool into the VRML format used by the

Simulink 3D Animation. Most CAD tools have VRML export filters available. In

addition, there are conversion utilities available from 3

parties that can

perform this task when the export filter isn’t available in the CAD tool directly.
