• The main Transform representing the CATIA product is always scaled by a factor
of 0.001 (conversion from millimeters to meters), regardless of the units used in the
CATIA document
Adjusting Resulting VRML files
Adjust exported VRML files to use the exported VRML models with the Simulink 3D
Animation software. You can perform these adjustments manually, as described in this
topic, or use the vrcadcleanup and vrphysmod functions to perform some of these
tasks.
• Adding DEF Names to Part Transforms
In the VRML file, assign a unique name for each VRML object. To do this, add the
DEF Object_Name statement to each part Transform line.
The following is an example of a VRML file that has DEF names added to the cylinder
assembly.
