About Default Layers
Creo Parametric can automatically place certain types of items on specified layers when they are created. You can establish up to 32 default layers in a model. To do this, set the configuration file option create_numbered_layers to yes.
You can then add these items to layers automatically as you create the items by setting the configuration file , def_layer<type-option layername>, where type-option is the item type, and layername is the name that you assign to the layer. Whenever you create an entity of a given item type, Creo Parametric automatically adds it to the specified default layer.
