About CATIA Start Parts
You can use custom CATIA V4 .model start parts when exporting parts or assemblies to the CATIA V4 .model file format. The custom start-part template files define nongeometric entities such as workspace, views, layers, fonts, colors, graphic standards, tolerance, and other parameters.
The attributes of the start parts are applied to the exported CATIA V4 .model files. The following parameters from the CATIA start-part template file are copied to the models:
Graphics standards
Colors
Tolerances
Thickness
Model comments
Initial view plane
Project file information
To access and use the CATIA start-part template files, you can select the Model preferences option, Export start model in the CATIA V4 export profile. If the start parts are missing, the exported CATIA V4 .model files use the default model parameter values.
