Layers

Every item in KernelCAD models has string property called "Layer Name". Layer Name should be considered as family name of the object. There is no separate "layer" objects created in KernelCAD software. In every operation, where layers are involved, only individual layer names are used to  to dynamically classify objects.

Layers are useful user-defined classification of objects independent of the child/parent relationship. The KernelCAD software itself does not modify or use layer names, unless requested by the user or programmatically

By default the Layer Name is an empty string (Default Layer).

The layer name can be used to store an application-defined string in the object. See details at User Data

In 3D Debugger Layer Name can be accessed and modified from the Model Explorer (Model > Explore in menu). To modify Layer Name select an object in the Model Explorer and type new name on the Layer combo box on the right hand side or select an existing name from the drop down list.

Layers Tab in the Model Explorer displays all objects in the model sorted by the Layer Name. Default layer contains all objects with empty Layer Name string. With the Layers Tab opened Layers menu appears, which allows to hide or show the layer's objects and renaming the layer (changing the Layer Name property for all object with the same Layer Name).

Programmatically individual Layer Name can be accessed via the IUserData interface, which can be queried from the correspondent ISection or IItem interface. Collection of all different layer names in the model can be accessed via the ILayers interface, obtained via IModel.
