Class: Sketchup::ComponentInstance

Inherits:
Drawingelement show all
Defined in:
lib/sketchup-api-stubs/stubs/Sketchup/ComponentInstance.rb

Overview

The ComponentInstance class is used to represent component instances of a component definition or components that have been dragged from the Component Browser and placed (thus, instanced) within the Model. Therefore, the ComponentInstance class contains a reference to a corresponding ComponentDefinition object and a Transformation object (which contains the location of the component in the Drawing Window).

Starting from SketchUp 2018+, the ComponentInstance class contains default attributes when created or imported. The attributes are: “Owner”, “Status”. See the Help article for more information. The dictionary cannot be deleted via ruby and an @raise ArgumentError will be raised. The key/value pairs in the dictionary can be deleted safely.

Examples:

entities = Sketchup.active_model.entities
definition = Sketchup.active_model.definitions[0]
transformation = Geom::Transformation.new([0,0,0])
componentinstance = entities.add_instance(definition, transformation)
status = componentinstance.add_observer observer

Parameters:

  • observer (Object) —

    An observer.

Returns:

  • (Boolean) —

    true if successful, false if unsuccessful.

end

#definition ⇒ Sketchup::ComponentDefinition

The definition method is used to retrieve the component definition for this component instance.

Examples:

# First create an instance for us to look at.
entities = Sketchup.active_model.entities
definition = Sketchup.active_model.definitions[0]
transformation = Geom::Transformation.new([0,0,0])

def definition
end

#definition=(definition) ⇒ Sketchup::ComponentDefinition

The definition= method is used to set the component definition for this component.

This method causes the instance to use a different definition, but it will use the same transformation to position it in the Model.

Examples:

# Assumes that the active model contains two different components.
instance1 = Sketchup.active_model.entities[0]
instance2 = Sketchup.active_model.entities[1]

# Grab handles to our two definitions.
definition1 = instance1.definition
definition2 = instance2.definition

# Replace 2nd instance with the 1st definition.
instance2.definition = definition1

Parameters:

Returns:

  UI.messagebox "Exploded the component instance"
else
  UI.messagebox "Failure"
end

Returns:

  • (Array<Sketchup:Entity>) —

    An array of entity objects if successful, false if unsuccessful

model = Sketchup.active_model
entities = model.active_entities
path = Sketchup.find_support_file("Bed.skp", "Components/Components Sampler/")

def glued_to
end

#glued_to=(drawing_element) ⇒ Sketchup::Face, ...

The #glued_to= method glues this instance to a drawing element. When moving this other drawing elment with the Move tool, the glued instance moves with it.

In SketchUp 2021.1 support for passing Group, Sketchup::ComponentInstance and Image was added.

Examples:

model = Sketchup.active_model
entities = model.active_entities

# Create a face
face = entities.add_face([[0, 0, 0], [100, 0, 0], [100, 100, 0], [0, 100, 0]])

# Add component
path = Sketchup.find_support_file("Bed.skp", "Components/Components Sampler/")
point = Geom::Point3d.new(10, 10, 0)
transformation = Geom::Transformation.new(point)
definitions = model.definitions
definition = definitions.load(path)
instance = entities.add_instance(definition, transformation)

# Make component "gluable"
definition.behavior.is2d = true

# Glue the component to the face.
# If you now move the face, the component will follow.
instance.glued_to = face

Parameters:

Returns:

Raises:

  • ArgumentError if the Behavior for this component doesn’t allow gluing, if the alignment is wrong, or if this would lead to cyclic gluing.

#outer_shell(instance) ⇒ Sketchup::Group?

The outer_shell method is used to compute the outer shell of the two instances representing manifold solid volumes (this || arg). If the specified objects (this and arg) do not represent manifold volumes, this method fails.

instance1 = entities[0]
instance2 = entities[1]
result = instance1.outer_shell(instance2)

def remove_observer(observer)
end

#show_differences(instance, verbose) ⇒ Boolean

The show_differences method is used to determine if a component instance is geometrically equivalent to another instance and in addition move the non- matching and matching geometry to new layers.

This method will move both instances to Layer0. Geometry that is the same in both components will be moved to a new layer named def_name + “_same”. Geometry that is not the same will be moved to a layer named def_name + “_diff”.

If verbose is true, a list of all the geometry that is different from one component to the other is displayed texturally in the Ruby Console.

Examples:

entities = Sketchup.active_model.entities
instance1 = entities[0]
instance2 = entities[1]
status = instance1.show_differences(instance2, true)

Parameters:

  • instance (Sketchup::ComponentInstance) —

    The instance to be compared with.

  • verbose (Boolean) —

    A boolean flag indicating whether to display a textural report of the found differences to the Ruby console.

Returns:

  • (Boolean) —

    true if the instances are geometrically equivalent, otherwise false.

Note:

Examples:

entities = Sketchup.active_model.entities
instance1 = entities[0]
instance2 = entities[1]
result = instance1.split(instance2)

Parameters:

Returns:

  • (Array(Sketchup::Group, Sketchup::Group, Sketchup::Group)) —

    A vector (array) of the three resultant groups if the two objects (this and arg) represent manifold solids and the operation succeeds otherwise nil is returned. The 3 groups are as follows: The intersection of volume 1 & volume 2, the difference of volume 1 minus volume 2, and the reverse difference of volume 2 minus volume 1.
