Instance Method Details

#[](entity_index) ⇒ Sketchup::Entity?

The #[] method is used to retrieve an entity by its index in an array of entities. The index is a number between 0 and entities.length - 1. In general, it is preferable to use the #each method to iterate though all of the entities in the collection as it will be much more efficient.

Examples:

entities = Sketchup.active_model.entities
entity = entities[0]

end

#active_section_plane ⇒ Sketchup::SectionPlane?

The active_section_plane method is used to access the currently active section plane in the Entities object.

Examples:

entities = Sketchup.active_model.entities
section_plane = entities.add_section_plane([50, 50, 0], [1.0, 1.0, 0])
entities.active_section_plane = section_plane
section_plane = entities.active_section_plane

#active_section_plane=(sec_plane) ⇒ Sketchup::SectionPlane?

The active_section_plane= method is used to set the active section plane in the Entities object.

Examples:

entities = Sketchup.active_model.entities
section_plane = entities.add_section_plane([50, 50, 0], [1.0, 1.0, 0])
entities.active_section_plane = section_plane

The #add_3d_text method is used to create 3D text. It will be added as edges and faces drawn at the origin.

Examples:

# Draw the word "test" at the origin of the model, aligned left, in
# Arial Bold, not italics, 1" in size, best tolerance quality, filled,
# with an extrusion size of 5".
entities = Sketchup.active_model.entities

entities = model.active_entities
center_point = Geom::Point3d.new
# Create an arc perpendicular to the normal or Z axis
normal = Geom::Vector3d.new(0, 0, 1)

Examples:

model = Sketchup.active_model
entities = model.active_entities
point1 = Geom::Point3d.new(0, 0, 0)
point2 = Geom::Point3d.new(20, 20, 20)

#add_cpoint(point) ⇒ Sketchup::ConstructionPoint

The add_cpoint method is used to create a construction point.

Examples:

entities = Sketchup.active_model.active_entities
point1 = Geom::Point3d.new(100, 200, 300)
constpoint = entities.add_cpoint(point1)

#add_curve(points) ⇒ Array<Sketchup::Edge> #add_curve(*points) ⇒ Array<Sketchup::Edge>

The add_curve method is used to create a curve from a collection of edges.

The arguments are either Points or an Array of Points. At least 2 points are required.

Examples:

entities = Sketchup.active_model.entities
curve = entities.add_curve([0, 0, 0], [0, 10, 0], [10, 20, 0])

The #add_dimension_linear method adds a linear dimension to the entities.

Examples:

entities = Sketchup.active_model.entities
# From point to point
dim = entities.add_dimension_linear([0, 0, 0], [50, 0, 0], [0, 20, 0])

# Between edge vertices
edge1 = entities.add_edges([70, 0, 0], [120, 0, 0])[0]
v0 = edge1.start
v1 = edge1.end
dim = entities.add_dimension_linear(v0, v1, [0, 20, 0])

# From an edge's midpoint to a construction point
edge2 = entities.add_edges([150, 0, 0], [200, 0, 0])[0]
p0 = edge2.start.position
p1 = edge2.end.position
mp = Geom::Point3d.new((p0.x + p1.x) / 2.0, (p0.y + p1.y) / 2.0, (p0.z + p1.z) / 2.0)
cp = entities.add_cpoint([150, 40, 0])
dim = entities.add_dimension_linear([edge2, mp], cp, [20, 0, 0])

#add_dimension_radial(arc_curve, leader_break_pt) ⇒ Sketchup::DimensionRadial

The add_dimension_radial method adds a radial dimension (i.e arc/circle radius/diameter dimension) to the entities.

Examples:

entities = Sketchup.active_model.entities
# Create a circle
center_point = Geom::Point3d.new(10, 10, 0)
vector = Geom::Vector3d.new(0, 0, 1)
edges = entities.add_circle(center_point, vector, 10)
circle = edges[0].curve
dim = entities.add_dimension_radial(circle, [30, 30, 0])

end

#add_edges(points) ⇒ Array<Sketchup::Edge> #add_edges(*points) ⇒ Array<Sketchup::Edge>

Note:

If the points form a closed loop, the first and last vertex will not merge. If you intend to create a face from the edges, use #add_face directly.

The #add_edges method is used to add a set of connected edges to the Sketchup::Entities collection.

Examples:

model = Sketchup.active_model
entities = model.active_entities
point1 = Geom::Point3d.new(0, 0, 0)
point2 = Geom::Point3d.new(20, 20, 20)
point3 = Geom::Point3d.new(20, 40, 20)
edges = entities.add_edges(point1, point2, point3)

end

#add_face(entities) ⇒ Sketchup::Face? #add_face(*entities) ⇒ Sketchup::Face?

Note:

A special case exists for any face created on the ground plane, in which case the vertex order is ignored and the face is always facing down.

The add_face method is used to create a face. You can call this method a number of ways:

- entities.add_face(edge1, edge2, edge3, ...)
- entities.add_face(edgearray)
- entities.add_face(pt1, pt2, pt3, ...)
- entities.add_face([pt1, pt2, pt3,...])
- entities.add_face(curve)

For the last form that takes a Curve, the curve must be closed - like a circle.

Examples:

model = Sketchup.active_model
entities = model.active_entities
points = []
points << [0, 0, 0]
points << [100, 0, 0]
points << [100, 100, 0]
points << [0, 100, 0]
# Add the face to the entities in the model
face = entities.add_face(points)

#add_faces_from_mesh(polygon_mesh, smooth_flags = Geom::PolygonMesh::AUTO_SOFTEN|Geom::PolygonMesh::SMOOTH_SOFT_EDGES, f_material = nil, b_material = nil) ⇒ Integer

The #add_faces_from_mesh method is used to add Face entities to the collection of entities from a Geom::PolygonMesh.

The smooth_flags parameter can contain any of the following values if passed. The constants were added in SketchUp 2014. For previous versions, numeric values have to be specified instead of the Ruby constants.

The 3rd and 4th parameters will accept a Material object or a string name of a material currently in the model.

Examples:

pm = Geom::PolygonMesh.new
pm.add_point([ 0, 0, 0]) # 1
pm.add_point([10, 0, 0]) # 2
pm.add_point([10, 10, 0]) # 3
pm.add_point([0, 10, 0]) # 4
pm.add_point([20, 0, 5]) # 5
pm.add_point([20, 10, 5]) # 6
pm.add_polygon(1, -2, 3, 4)
pm.add_polygon(2, 5, 6, -3)

# Create a new group that we will populate with the mesh.
group = Sketchup.active_model.entities.add_group
material1 = Sketchup.active_model.materials.add('My Green Material')
material1.color = 'green'
material2 = Sketchup.active_model.materials.add('My Red Material')
material2.color = 'red'
smooth_flags = Geom::PolygonMesh::NO_SMOOTH_OR_HIDE
group.entities.add_faces_from_mesh(pm, smooth_flags, material1, material2)

#add_group(entities) ⇒ Sketchup::Group #add_group(*entities) ⇒ Sketchup::Group

Note:

Calling add_group with entities in its parameters has been known to crash SketchUp before version 8.0. It is preferable to create an empty group and then add things to its Entities collection.

The add_group method is used to create an empty group or a group with entities.

Examples:

model = Sketchup.active_model
entities = model.active_entities
group = entities.add_group

#add_image(path, point, width, height = 0.0) ⇒ Sketchup::Image?

The add_image method is used to add an image to the collection of entities.

The width and height are measured in model units (i.e. inches). If the height is not given, then it is computed from the width to preserve the aspect ratio of the image.

Examples:

model = Sketchup.active_model
entities = model.active_entities
point = Geom::Point3d.new(10, 20, 30)
image = entities.add_image(Sketchup.find_support_file('ColorWheel.png',
  'Resources/../..'), point, 300)

#add_instance(definition, transform) ⇒ Sketchup::ComponentInstance

The add_instance method adds a component instance to the collection of entities.

Examples:

model = Sketchup.active_model
entities = model.active_entities
point = Geom::Point3d.new(10, 20, 30)
transform = Geom::Transformation.new(point)
path = Sketchup.find_support_file("Bed.skp", "Components/Components Sampler/")
definitions = model.definitions
componentdefinition = definitions.load(path)
instance = entities.add_instance(componentdefinition, transform)

#add_line(point1, point2) ⇒ Sketchup::Edge

The add_line method is used to add an edge to the collection of entities. This is not to be confused with the concept of a “line” from a geometric sense, which is an invisible object represented by an Array of a point and a vector. (See the Array class for more information on geometric lines in SketchUp.)

This method is the same as add_edges method, but returns a single edge.

Examples:

model = Sketchup.active_model
entities = model.active_entities
point1 = Geom::Point3d.new(0, 0, 0)
point2 = Geom::Point3d.new(20, 20, 20)
line = entities.add_line(point1, point2)

end

#add_ngon(center, normal, radius, numsides = 24) ⇒ Array<Sketchup::Edge>

The add_ngon method is used to create a multi-sided polygon.

Examples:

entities = Sketchup.active_model.entities
center = Geom::Point3d.new
normal = Geom::Vector3d.new(0, 0, 1)
radius = 100
numsides = 6
edges = entities.add_ngon(center, normal, radius, numsides)

def add_ngon(center, normal, radius, numsides = 24)
end

#add_observer(observer) ⇒ Boolean

The add_observer method is used to add an observer to the current object.

Examples:

# This is an example of an observer that watches the entities collection.
# It writes to the console everytime new entities are added to the model.
class MyEntitiesObserver < Sketchup::EntitiesObserver
  def onElementAdded(entities, entity)
    puts "onElementAdded: #{entity} was added to the model."
  end
end

# Attach the observer
entities = Sketchup.active_model.entities
entities.add_observer(MyEntitiesObserver.new)

def add_observer(observer)
end

#add_section_plane(plane) ⇒ Sketchup::SectionPlane?

The add_section_plane method adds a section plane object to the entities.

Examples:

# Create a section plane
model = Sketchup.active_model
section_plane = model.entities.add_section_plane([50, 50, 0], [1.0, 1.0, 0])
# Activate it
section_plane.activate
# Make sure section planes are visible

#add_text(text, point, vector) ⇒ Sketchup::Text #add_text(text, instance_path_and_pt, vector) ⇒ Sketchup::Text #add_text(text, instance_array_and_pt, vector) ⇒ Sketchup::Text

The #add_text method adds a note or label text entity to the entities.

Examples:

model = Sketchup.active_model
entities = model.entities
point = Geom::Point3d.new(10, 10, 10)
text = entities.add_text("This is a Test", point)

#build {|builder| ... } ⇒ nil

Note:

While using #build it is important to not add or remove vertices by other means of the builder. Also don’t modify the position of the vertices in the Sketchup::Entities container geometry is added to. Doing so can break the vertex-cache that de-duplicates the vertices.

Creates an Sketchup::EntitiesBuilder that can be used to generate bulk geometry with performance in mind. This is particularly useful for importers where the geometry is already well defined and one wants to recreate it without further processing.

The call to #build starts an implicit operation, even if no other model changes are made within the block. This is not the same as Model#start_operation, so it’s still recommended to wrap all model changes, including #build with Model#start_operation and Model#commit_operation.

Refer to the documentation of Sketchup::EntitiesBuilder for more details.

Examples:

model = Sketchup.active_model
model.entities.build { |builder|
  edge = builder.add_edge([0, 0, 0], [9, 0, 0])
  edge.material = 'red'
  face = builder.add_face([0, 0, 0], [9, 0, 0], [9, 9, 0], [0, 9, 0])
  face.material = 'maroon'
}

end

#count ⇒ Integer

Note:

Since SketchUp 2014 the count method is inherited from Ruby’s Enumerable mix-in module. Prior to that the #count method is an alias for #length.

Examples:

entities = Sketchup.active_model.entities
number = entities.count

def count
end

#each {|entity| ... } ⇒ nil

Note:

Don’t remove content from this collection while iterating over it with #each. This would change the size of the collection and cause elements to be skipped as the indices change. Instead copy the current collection to an array using to_a and then use each on the array, when removing content.

The #each method is used to iterate through the entities in the collection of entities.

Examples:

model = Sketchup.active_model
entities = model.entities
entities.each { | entity| puts entity }

#erase_entities(entities) ⇒ nil #erase_entities(*entities) ⇒ nil

Note:

It’s faster to use this method and erase in bulk than to iterate individual drawing elements calling Drawingelement#erase!.

The #erase_entities method is used to erase one or more entities from the model.

Examples:

model = Sketchup.active_model
entities = model.active_entities
points = []
points << [0, 0, 0]
points << [100, 0, 0]
points << [100, 100, 0]
points << [0, 100, 0]

# Add the face to the entities in the model.
face = entities.add_face(pts)
faces = entities.grep(Sketchup::Face)
entities.erase_entities(faces)

Raises:

  • (ArgumentError) —

    if the given entities contains instances or definitions are used by Model#active_path.

#fill_from_mesh(polygon_mesh, weld_vertices = true, smooth_flags = Geom::PolygonMesh::AUTO_SOFTEN|Geom::PolygonMesh::SMOOTH_SOFT_EDGES, f_material = nil, b_material = nil) ⇒ Boolean

The #fill_from_mesh method is used to add faces and edges to the collection of entities from a Geom::PolygonMesh. It requires that the entities collection to be filled is empty. It has higher performance than #add_faces_from_mesh, but does less error checking as it builds the geometry.

The smooth_flags parameter can contain any of the following values if passed. The constants were added in SketchUp 2014. For previous versions, numeric values have to be specified instead of the Ruby constants:

The 4rd and 5th parameters will accept a Material object or a string name of a material currently in the model.

Examples:

pm = Geom::PolygonMesh.new
pm.add_point([  0,  0, 0]) # 1
pm.add_point([ 10,  0, 0]) # 2
pm.add_point([ 10, 10, 0]) # 3
pm.add_point([  0, 10, 0]) # 4
pm.add_point([ 20,  0, 5]) # 5
pm.add_point([ 20, 10, 5]) # 6
pm.add_polygon(1, -2, 3, 4)
pm.add_polygon(2, 5, 6, -3)

# Create a new group that we will populate with the mesh.
group = Sketchup.active_model.entities.add_group
material = Sketchup.active_model.materials.add('My Red Material')
material.color = 'red'
smooth_flags = Geom::PolygonMesh::HIDE_BASED_ON_INDEX
group.entities.fill_from_mesh(pm, true, smooth_flags, material)

#intersect_with(recurse, transform1, entities1, transform2, hidden, entities2) ⇒ nil

The intersect_with method is used to intersect an entities, component instance, or group object with a entities object.

Examples:

model = Sketchup.active_model
entities = model.active_entities

# Create a group to intersect with the model
group1 = entities.add_group
face1 = group1.entities.add_face([0, 0, 0], [100, 0, 0], [100, 100, 0], [0, 100, 0])
face1.pushpull(-40)

# Add geometry into the model
face2 = entities.add_face([50, 50, 0], [200, 50, 0], [200, 200, 0], [50, 200, 0])
face2.pushpull(-100)

entities1 = group1.entities
entities2 = entities.to_a

transformation1 = Geom::Transformation.new
transformation2 = group1.transformation

# Intersect the group and model geometry
entities.intersect_with(true, transformation1, entities1, transformation2, true, entities2)

#length ⇒ Integer

The #length method is used to retrieve the number of entities in the collection of entities.

Examples:

model = Sketchup.active_model
entities = model.entities
number = entities.length

#model ⇒ Sketchup::Model

The model method is used to retrieve the model that contains the collection of entities.

Examples:

model = Sketchup.active_model
entities = model.entities
group = entities.add_group
face = group.entities.add_face([0, 0, 0], [100, 0, 0], [100, 100, 0], [0, 100, 0])
model = group.entities.model

def model
end

#parent ⇒ Sketchup::ComponentDefinition, Sketchup::Model

The parent method is used to retrieve the parent or object that contains the collection of entities. A parent can be either a Model or ComponentDefinition object.

Examples:

model = Sketchup.active_model
entities = model.entities
group = entities.add_group
face = group.entities.add_face([0, 0, 0], [100, 0, 0], [100, 100, 0], [0, 100, 0])
model = group.entities.parent

#remove_observer(observer) ⇒ Boolean

The remove_observer method is used to remove an observer from the current object.

Examples:

# This is an example of an observer that watches the entities collection.
# It writes to the console everytime new entities are added to the model.
class MyEntitiesObserver < Sketchup::EntitiesObserver
  def onElementAdded(entities, entity)
    puts "onElementAdded: #{entity} was added to the model."
  end
end

# Attach the observer
entities = Sketchup.active_model.entities
my_observer = MyEntitiesObserver.new
entities.add_observer(my_observer)
# Add an entity to the model, and the observer will trigger.
entities.add_line([0,0,0], [100,0,0])
# Remove the oberserver and the observer will no longer trigger.
status = entities.remove_observer(my_observer)

#transform_by_vectors(sub_entities, vectors) ⇒ Sketchup::Entities

The transform_by_vectors method is used to apply several vectors to several sub-entities all at once.

Examples:

model = Sketchup.active_model
entities = model.active_entities

# Create a group with geometry to transform
group1 = entities.add_group
face1 = group1.entities.add_face([0, 0, 0], [100, 0, 0], [100, 100, 0], [0, 100, 0])
face1.pushpull(-40)

# Raise vertices in selection by their distance to the origin.
with_vertices = group1.entities.select { |entity| entity.respond_to?(:vertices) }
vertices = with_vertices.flat_map(&:vertices).uniq
lengths = vertices.map { |vertex| vertex.position.distance(ORIGIN) }
vectors = lengths.map { |length| Geom::Vector3d.new(0, 0, length) }

entities.transform_by_vectors(vertices, vectors)

#transform_entities(transform, entities) ⇒ Boolean

The transform_entities method is used to apply a transform to several sub-entities all at once.

If you are transforming entities in the active drawing context or any of its parent drawing contexts, the transformation will be interpreted as relative to the global coordinate system. Otherwise the transformation will be interpreted as being on the local coordinate system.

Examples:

entities = Sketchup.active_model.entities
# Add edges to the model at the origin.
edge1 = entities.add_line([0, 0, 0], [100, 100, 100])
edge2 = entities.add_line([0, 0, 0], [200, -10, -10])

# After the transformation, the edges will be moved 100 inches
# away from the origin, on the x axis.
transformation = Geom::Transformation.new([100, 0, 0])
entities.transform_entities(transformation, [edge1, edge2])

#weld(edges) ⇒ Array<Sketchup::Curve>

The #weld method takes a set of edges and find all possible chains of edges and connect them with a Curve.

A curve will not cross another curve. They will split where multiple curves meet.

Examples:

model = Sketchup.active_model
entities = model.active_entities
edges = []
edges << entities.add_line([0, 0, 0], [100, 20, 0])
edges << entities.add_line([100, 20, 0], [130, 200, 50])
edges << entities.add_line([130, 200, 50], [130, 300, 50])
curves = model.active_entities.weld(edges)

Raises:

  • (ArgumentError) —

    if the given entities are not part of the same Sketchup::Entities collection.
