Input files of category 3 models include layered files.

The following illustrations assume that you have one base.
Note: When refining layered input files, multiple layers can be mapped together to simplify the file if necessary.

Model 6: [all layers]
Provide a single layered input file in which each layer in the file represents a layer in the version plan.

 
Model 7: [some layers]ⁿ
Provide two or more layered files in which each file contains two or more layers. Each layer must represent a layer in the version plan and contain either base or version content.

 
Model 8: [1 base layer+ 1 version layer], [1 layer]ⁿ

Provide two or more layered files:

• One file containing two or more layers: one layer with base content and other layers with version content
• One or more files each containing content for only one layer (base or version content).
