The ComponentDefinition class is used to define the contents for a component (the entities contained within a component). The ComponentDefinition can be thought of as the class used to represent components in the SketchUp Component Browser.

Instance Methods

<=>
The <=> method is used to compare two ComponentDefinition objects for sorting. The comparison is done based on the component name.
Syntax:
status = componentdefinition1 <=> componentdefinition2
Arguments:
componet1 - the first component in the comparison component2 - the second component in the comparison
Return Value:
status - a -1 if component1 is less then component2. A 1 if component1 greater than component2
Comments:
Example:
path1=Sketchup.find_support_file "BedTraditional.skp" ,"Components/Furniture/" path2=Sketchup.find_support_file "TableRound36.skp", "Components/Furniture/" model = Sketchup.active_model definitions = model.definitions componentdefinition1 = definitions.load path1 componentdefinition2 = definitions.load path2 # Yields a -1 status = componentdefinition1 <=> componentdefinition2

==
The == method is used to test if two ComponentDefinition objects are the same (based on their address in memory).
Syntax:
status = componentdefinition1 == componentdefinition2
Arguments:
componetdefinition1 - the first component definition in the comparison componentdefinition2 - the second component definition in the comparison
Return Value:
status - true if the ComponentDefinition objects are the same object. False if the objects are not the same.
Comments:
Example:
path1=Sketchup.find_support_file "BedTraditional.skp" ,"Components/Furniture/" path2=Sketchup.find_support_file "TableRound36.skp", "Components/Furniture/" model = Sketchup.active_model definitions = model.definitions componentdefinition1 = definitions.load path1 componentdefinition2 = definitions.load path2 # Yields a false status = componentdefinition1 == componentdefinition2

behavior
The behavior method is used to retrieve the Behavior object associated with a component definition.
Syntax:
behavior = componentdefinition.behavior
Arguments:
Return Value:
behavior - a Behavior object if successful
Comments:
Example:
path=Sketchup.find_support_file "BedTraditional.skp" ,"Components/Furniture/" model = Sketchup.active_model definitions = model.definitions componentdefinition = definitions.load path behavior = componentdefinition.behavior if (behavior) UI.messagebox behavior else UI.messagebox "Failure" end

count_instances
The count_instances method is used to count the number of component instances in a model using this component definition.

Arguments:
Return Value:
count - the number of component instances of this component definition (if successful)
Comments:
Example:
path=Sketchup.find_support_file "BedTraditional.skp" ,"Components/Furniture/" model = Sketchup.active_model definitions = model.definitions componentdefinition = definitions.load path number = componentdefinition.count_instances if (number) UI.messagebox number else UI.messagebox "Failure" end

description
The description method is used to retrieve the description of the component definition.
Syntax:
description = componentdefinition.description
Arguments:
Return Value:
description - the description of the component definition if successful
Comments:
Component definitions do not have a description, by default.
Example:
# Set the description componentdefinition.description="This is a traditional bed" description = componentdefinition.description

description=
The description= method is used to set the description for the component definition.
Syntax:
status = componentdefinition.description = description
Arguments:
Return Value:
status - the description if successful, false if unsuccessful
Comments:
Example:
componentdefinition.description="This is a traditional bed" description = componentdefinition.description

entities
The entities method retrieves a collection of all the entities in the component definition
Syntax:
entities=componentdefinition.entities
Arguments:
Return Value:
entities - an Entities object if successful
Comments:
Example:
entities = componentdefinition.entities if (entities) length = entities.length UI.messagebox "Number of Entities in Component: #{length}" else UI.messagebox "Failure" end

group?
The group? method is used to determine if this component definition is used to hold the elements of a group.
Syntax:
status = componentdefinition.group?
Arguments:
Return Value:
status - true if the definition is used to hold a group, false if the definition does not hold a group.
Comments:
Example:
path=Sketchup.find_support_file "BedTraditional.skp" ,"Components/Furniture/" model = Sketchup.active_model definitions = model.definitions componentdefinition = definitions.load path status = componentdefinition.group? if (status) UI.messagebox status else UI.messagebox "No Groups in the Component" end

guid
The guid method is used to retrieve the unique identifier of this component definition.
Syntax:
guid = componentdefinition.guid
Arguments:
Return Value:
guid - a string guid if successful
Comments:
Example:
guid = componentdefinition.guid

hidden?
The hidden method is used to determine if this component definition should be hidden on the component browser.
Syntax:
status = componentdefinition.hidden?
Arguments:
Return Value:
status - true if the definition should be hidden, false if the definition should not be hidden
Comments:
Example:
status = componentdefinition.hidden?

instances
The instances method is used to determine the number of component instances that use this component definition
Syntax:
instances = componentdefinition.instances
Arguments:
Return Value:
instances - the number of instances based on this component definition (if successful)
Comments:
Example:
status = componentdefinition.image? if (status) UI.messagebox "Component definition defines an image" else UI.messagebox status UI.messagebox "Component definition does not define an image" end

image?
The image method is used to determine if this component definition is used to define an image.
Syntax:
status = componentdefinition.image?
Arguments:
Return Value:
status - true if the component definition defines an image, false if the component definition does not define an image.
Comments:
Example:
status = componentdefinition.image? if (status) UI.messagebox "Component definition defines an image" else UI.messagebox status UI.messagebox "Component definition does not define an image" end

insertion_point
The insertion_point method is used to retrieve the Point3d object where the component was inserted.
Syntax:
point = componentdefinition.insertion_point
Arguments:
Return Value:
point - the Point3d where the component was inserted if successful. False if unsuccessful.

point = Geom::Point3d.new 10,20,30 transform = Geom::Transformation.new point model = Sketchup.active_model entities = model.active_entities path=Sketchup.find_support_file "BedTraditional.skp" ,"Components/Furniture/" definitions = model.definitions\ componentdefinition = definitions.load path instance = entities.add_instance componentdefinition, transform\ point = componentdefinition.insertion_point

internal?
The internal? method is used to determine if the component definition is internal to the Component Browser
Syntax:
status = componentdefinition.internal?
Arguments:
Return Value:
status - true if the component definition is internal to SketchUp's Component Browser. False if the component definition is not internal to SketchUp.
Comments:

name=
The name= method is used to set the name of the component definition.
Syntax:
name - componentdefinition.name = name
Arguments:
Return Value:
name - the name assigned to the component definition if successful
Comments:
Example:
path=Sketchup.find_support_file "BedTraditional.skp" ,"Components/Furniture/" model = Sketchup.active_model definitions = model.definitions componentdefinition = definitions.load path name = componentdefinition.name="Bed"

path
The path method is used to retrieve the path where the component was loaded.
Syntax:
path = componentdefinition.path
Arguments:
Return Value:
path - a valid path if successful, false if unsuccessful
Comments:
Returns nil if it is an internal component.

save_thumbnail
The save_thumbnail method is used to save a thumbnail image to a file.
