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]

Parameters:

  • entity_index (Integer) —

    The index for a specific entity.

Returns:

    Height of the text in inches.

  • tolerance (Numeric) (defaults to: 0.0) —

    Tolerance of the curve creation. Defaults to 0.0, which creates the highest possible curve quality.

  • z (Numeric) (defaults to: 0.0) —

    z position in inches.

  • is_filled (Boolean) (defaults to: true) —

    true for filled, which will put a face between the edges of the letters.

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

Parameters:

  • arc_curve (Sketchup::ArcCurve) —

    an ArcCurve object to which the dimension is to be attached.

#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)
edges = entities.add_edges point1, point2

#add_face(some_entities) ⇒ Sketchup::Face

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.

Note that 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.

Examples:

depth = 100
width = 100
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)

#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 objects to the collection of entities from a 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 Sketchup::Entities.sketchupsketchup::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('green')
smooth_flags = Geom::PolygonMesh::NO_SMOOTH_OR_HIDE
group.entities.add_faces_from_mesh(pm, smooth_flags, material)

Parameters:

  • polygon_mesh (Geom::PolygonMesh)
  • smooth_flags (Integer) (defaults to: Geom::PolygonMesh::AUTO_SOFTEN|Geom::PolygonMesh::SMOOTH_SOFT_EDGES) —

    flags for softening and smoothing of edges.

  • f_material (Sketchup::Material, String) (defaults to: nil) —

    material to paint front faces with.

  • b_material (Sketchup::Material, String) (defaults to: nil) —

    material to paint back faces with.

Returns:

  • (Integer) —

    Number of faces created

#add_group(entities) ⇒ Sketchup::Group

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

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.

Examples:

model = Sketchup.active_model
entities = model.active_entities
group = entities.add_group
if (group)
  UI.messagebox group
else
  UI.messagebox "Failure"
end

#add_image(filename, point, width, height) ⇒ 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 "Shapes.jpg", point, 300
if (image)
  UI.messagebox image
else
  UI.messagebox "Failure"
end

Parameters:

  • filename (String) —

    A filename for the image file.

  • point (Geom::Point3d) —

    A Point3d object representing the insertion point of the image.

  • width (Numeric) —

    Width for the image.

  • height (Numeric) —

    height for the image if you want to control width and height independently.

Returns:

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

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

Examples:

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 "Bed.skp",
  "Components/Components Sampler/"
definitions = model.definitions
componentdefinition = definitions.load path
instance = entities.add_instance componentdefinition, transform
if (instance)
  UI.messagebox instance

#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
if (line)
  UI.messagebox line
else
  UI.messagebox "Failure"
end

Parameters:

  • point1 (Geom::Point3d) —

    Point3d object representing the edge’s starting point.

  • point2 (Geom::Point3d) —

    Point3d object representing the edge’s ending point.

#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('red')
smooth_flags = Geom::PolygonMesh::HIDE_BASED_ON_INDEX
group.entities.fill_from_mesh(pm, true, smooth_flags, material)

Parameters:

  • polygon_mesh (Geom::PolygonMesh)
  • weld_vertices (Boolean) (defaults to: true) —

    This argument has no effect and is kept for compatibility reasons. Points are always merged.

  • smooth_flags (Integer) (defaults to: Geom::PolygonMesh::AUTO_SOFTEN|Geom::PolygonMesh::SMOOTH_SOFT_EDGES) —

    flags for softening and smoothing of edges.

  • f_material (Sketchup::Material, String) (defaults to: nil) —

    material to paint front faces with.

  • b_material (Sketchup::Material, String) (defaults to: nil) —

    material to paint back faces with.

Returns:

  • (Boolean)

#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:

entities.intersect_with recurse, transformation1, entities1,
  transformation2, hidden, entities2

Parameters:

  • recurse (Boolean) —

    true if you want this entities object to be recursed (intersection lines will be put inside of groups and components within this entities object).

  • transform1 (Geom::Transformation) —

    The transformation for this entities object.

  • entities1 (Sketchup::Entities) —

    The entities object where you want the intersection lines to appear.

  • transform2 (Geom::Transformation) —

    The transformation for entities1.

  • hidden (Boolean) —

    true if you want hidden geometry in this entities object to be used in the intersection.

  • entities2 (Sketchup::Entity, Array<Sketchup::Entity>) —

    A single entity, or an array of entities.

Returns:

  • (nil)

#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
entities.add_cpoint([10, 10, 10])
number = entities.length

Returns:

  • (Integer)

#model ⇒ Sketchup::Model

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

Examples:

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

Returns:

  • (Sketchup::Model) —

    the model that contains the collection of entities if successful.

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:

coordinates = [10, 10, 10]
model = Sketchup.active_model
entities = model.entities
point = Geom::Point3d.new coordinates
text = entities.add_text "This is a Test", point
parent = entities.parent

#remove_observer(observer) ⇒ Boolean

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

Examples:

entities = Sketchup.active_model.entities
status = entities.remove_observer observer

Parameters:

  • observer (Object) —

    An observer.

Returns:

  • (Boolean) —

    true if successful, false if unsuccessful.

model = Sketchup.active_model
entities = model.entities
entities.add_cpoint([10, 10, 10])
number = entities.size

Returns:

  • (Integer)

#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:

# Need better Ruby example.
entities = entities.transform_by_vectors sub_entities, vector_array

Parameters:

Returns:

def transform_by_vectors(sub_entities, vectors)
end

#transform_entities(transform, entities) ⇒ Boolean

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

Important note: If you apply a transformation to entities that are not in the current edit context (i.e. faces that are inside a group), SketchUp will apply the transformation incorrectly, since the geometry has one origin and the current edit context has another. You can correct for this by watching the Model.edit_transform and Model.active_path. See ModelObserver.onActivePathChanged for more information.

Examples:

entities = Sketchup.active_model.entities
entities.add_line([0,0,0],[100,100,100])
entities.add_line([0,0,0],[200,-10,-10])

entities_to_transform = []
entities_to_transform.push(entities[0])
entities_to_transform.push(entities[1])

transform = Geom::Transformation.new([100,0,0])
entities.transform_entities(transform, ent1, ent2, ent3)

Parameters:

Returns:

  • (Boolean) —

    results of the transform.
