Overview

Note:

As of SketchUp 2020 “Layers” were renamed to “Tags” in the UI. The API retains the use of “Layer” for compatibility and is synonymous with “Tag”.

Allows layers to be organized in folders. Folders may have duplicate names.

Instance Method Details

#<=>(other) ⇒ Integer^?

The #<=> method is used to compare two layer folders based on their names. This enables the Ruby Array#sort method to sort SketchUp layer folders.

Examples:

model = Sketchup.active_model
layers = model.layers
folder1 = layers.add_folder('Folder1')
folder2 = layers.add_folder('Folder2')
comparison = folder1 <=> folder2 # Returns: -1
comparison = folder1 <=> folder1 # Returns: 0
comparison = folder2 <=> folder1 # Returns: 1

Parameters:

• other (Object)

Returns:

• (Integer, nil) —

  -1 if the receiver should appear before other. 1 if the receiver should appear after other. 0 if the receiver and other are equal. nil if other is not comparable with the receiver.

Version:

• SketchUp 2021.0

#==(other) ⇒ Boolean

The #== method is used to determine if two layer folders are the same.

Examples:

model = Sketchup.active_model
layers = model.layers
folder1 = layers.add('Folder1')
folder2 = layers.add('Folder2')
equal = folder1 == folder2

Parameters:

• other (Object)

Returns:

• (Boolean)
