About Exporting Layer Information
You can export and import layers. To export layers, you can:
Specify the layer IDs using Specify Id in the SETUP LAYER menu if the kind of export does not support named layers.
Specify the layer name.
Some kinds of export support a single layer per entity. If an entity resides on more than one layer, only the highest layer ID (assigned the largest number) is exported as the layer of the entity.
The layer name for an entity read from the Neutral format is INTF <nnn>, where <nnn> is the layer ID.
You can export layer information for detail entities in Drawing mode. You can set the intf2d_out_blanked_layers configuration option to yes to include blanked layer information in the export to DXF, DWG and STEP files.
If objects such as quilts, datum curves, and so on, have a blanked layer status and the intf2d_out_blanked_layers is set tono, these objects are not exported.
If assembly components are assigned individual layers, when you export assemblies to IGES in the flat mode:
Interface IDs of layers are output as IGES levels. In an IGES file, assembly components are associated with levels instead of layers.
If an assembly component is placed on a layer and blanked, all geometric entities of the blanked component are marked as invisible in an IGES file.
If an assembly has a subassembly, to output layer information of the subassembly when the top-level assembly is output to IGES, you can assign a layer to the subassembly. At the subassembly level, place all the components of the subassembly on this layer, and assign an interface ID to the layer.
