Class: Sketchup::ComponentInstance

Inherits:
Drawingelement show all
Defined in:
SketchUp/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.

componentinstance = entities.add_instance(definition, transformation)
status = componentinstance.add_observer observer

Parameters:

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]

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:

Version:

  • SketchUp 6.0

width = 100
path=Sketchup.find_support_file "Bed.skp",
  "Components/Components Sampler/"
model = Sketchup.active_model
entities = model.active_entities
pts = []
pts[0] = [0, 0, 0]
pts[1] = [width, 0, 0]
pts[2] = [width, depth, 0]
pts[3] = [0, depth, 0]
# Add the face to the entities in the model
face = entities.add_face pts
point = Geom::Point3d.new 10,10,0
transform = Geom::Transformation.new point
definitions = model.definitions
componentdefinition = definitions.load path
instance = entities.add_instance componentdefinition, transform
begin

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:

Parameters:

Returns:

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