Layer Categories Editor

There are three predefined categories which are always listed at the top of the Categories Editor. These categories cannot be deleted.

All Layers – This category automatically includes all the layers.

Reference Layers – This category automatically includes all reference layers.

Selected Layers – This category automatically includes all the currently selected layers. Consequently, its content will vary.

Categories you create are added below the predefined categories.

You can:

• Click a category to select it.

  You can select more than one category by holding down the key.

• Double-click a user-defined category name to change it.

  The number of layers in a category appears to the right of its name.

Buttons

There are two buttons that appear before each category's name:

• Pick – Selects all the layers in the category.
• Eye – Turns on or off the visibility of all layers in the category as well as all objects on those layers. The visibility state of a category is automatically passed down to all of its layers.

  If the icon is:

  • Eye open – All layers in the category are visible.
  • Eye half closed – Some layers in the category are visible.
  • Eye crossed out – All layers in the category are invisible.
