#curve ⇒ Sketchup::Curve?

The curve method is used to get the Curve object that this edge belongs to, if any. Note that if the edge is part of an arc instead of a random curve, then this method will return an ArcCurve object.

Examples:

edge = Sketchup.active_model.entities.add_line([0,0,0],[100,100,0])
curve = edge.curve
if (curve)
  # If it is a curve, display a pointer to the curve
  UI.messagebox curve
else
  UI.messagebox "Failure: Not a Curve"
end

Returns:

  • (Sketchup::Curve, nil) —

    returns a Curve object if it is a curve, nil if it is not a curve

Version:

  • SketchUp 6.0

# File 'SketchUp/Sketchup/Edge.rb', line 99

def curve
end

#end ⇒ Sketchup::Vertex

The end method is used to retrieve the Vertex object at the end of the edge.

Examples:

edge = Sketchup.active_model.entities.add_line([0,0,0],[100,100,0])
vertex = edge.end
if (vertex)
  # display a pointer to the Vertex
  UI.messagebox vertex
else
  UI.messagebox "Failure"
end
point = vertex.position
# Let's get the Point3d of the vertex
if (point)
  UI.messagebox point
else
  UI.messagebox "Failure"
end

Returns:

end

#explode_curve ⇒ Sketchup::Edge

The explode_curve method is used to explode an edge as though it were an ArcCurve.

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
# I just happen to know that the second entity in the
# entities objects is an edge.
entity1 = entities[1]
curve = entity1.explode_curve
if (curve)
  UI.messagebox curve
else
  UI.messagebox "Failure"
end

#faces ⇒ Array<Sketchup::Face>

The faces method is used to retrieve all of the faces common to the edge.

Examples:

edge = Sketchup.active_model.entities.add_line([0,0,0],[100,100,0])
faces = edge.faces
if (faces)
  # Display the pointer to the first face returned in the array
  UI.messagebox faces[0]
else
  UI.messagebox "Failure: No Faces Found"
end

Returns:

# File 'SketchUp/Sketchup/Edge.rb', line 174

def faces
end

#find_faces ⇒ Integer

The find_faces method is used to create all of the Faces that can be created with this edge. For example, if you use the API to draw three edges that form a triangle, the face between them will not show up because you’ve only drawn the edges, but if you call find_faces on one of the edges, the triangle will be filled in.

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
# I just happen to know that the second entity in the
# entities objects is an edge.
entity1 = entities[1]
# Getting zero.
number = entity1.find_faces
if (number)
  UI.messagebox "I created " + number.to_s + " faces."
else
  UI.messagebox "Failure"
end

Returns:

  • (Integer) —

    the number of faces found

#length ⇒ Length #length(transform) ⇒ Length

The #length method is used to retrieve the length of an edge in current units.

You can pass in an optional Geom::Transformation (or an array that can represent a transformation), to correct for a parent group’s transformation. For example, if an edge is inside of a group that is scaled to 200%, the length method will return the unscaled length of the edge. So by passing a 200% transformation object to this method, you can account for that to get the “visual” length of the edge.

Examples:

edge = Sketchup.active_model.entities.add_line([0, 0, 0], [100, 100, 0])
puts "#{edge.length} (#{edge.length.inspect})"

Overloads:

  • #length ⇒ Length

    Returns the length of the edge.

    Returns:

    • (Length) —

      the length of the edge

  • #length(transform) ⇒ Length

    Returns the length of the edge.

    Parameters:

    • transform (Geom::Transformation) —

      A Transformation object or array that can be interpreted as a Transformation object.

    Returns:

    • (Length) —

      the length of the edge

def length(*args)
end

#line ⇒ Array(Geom::Point3d, Geom::Vector3d)

The line method is used to retrieve the line defined by the edge. Lines in SketchUp aren’t visible entities but geometric constructs represented by an Array with a Point3d and a Vector3d. See the Geom module and the Array class for more information on lines.

Examples:

edge = Sketchup.active_model.entities.add_line([0,0,0],[100,100,0])
# Returns a 3D ray
line = edge.line
if (line)
  UI.messagebox line
else
  UI.messagebox "Failure"
end

Returns:

# File 'SketchUp/Sketchup/Edge.rb', line 259

def line
end

#other_vertex(vertex1) ⇒ Sketchup::Vertex

The other_vertex method is used to find the opposite vertex given one vertex of the edge.

Examples:

edge = Sketchup.active_model.entities.add_line([0,0,0],[100,100,0])
# Get the end vertex of an edge
vertex = edge.end
# Should find the starting vertex
othervertex = edge.other_vertex vertex
if (othervertex)
  UI.messagebox othervertex
else
  UI.messagebox "Failure"
end
# The Point3d for the vertex
point = othervertex.position
if (point)
  UI.messagebox point
else
  UI.messagebox "Failure"
end

#reversed_in?(face) ⇒ Boolean

The #reversed_in? method is used to determine if the edge is reversed in a face’s bounding loop.

Examples:

model = Sketchup.active_model
entities = model.active_entities
points = []
points[0] = [0, 0, 0]
points[1] = [9, 0, 0]
points[2] = [9, 9, 0]
points[3] = [0, 9, 0]
# Add the face to the entities in the model
face = entities.add_face(points)
edge = face.edges[0]
if edge.reversed_in?(face)
  face.reverse!
end

Parameters:

Returns:

  • (Boolean)
  • (Boolean) —

    true if the edge is reversed, false if it is not reversed. nil if the edge and face is not connected.

#smooth=(value) ⇒ Boolean

Note:

The soft and smooth properties are normally set in pairs. You can observer this when the Soften/Smooth Edges feature or holding down Ctrl when using the Eraser Tool.

The #smooth= method is used to set the edge to be smooth.

A smooth edge will cause the shading between connected faces to blend to a smooth transition. The edge will still be visible.

Examples:

edge = Sketchup.active_model.entities.add_line([0,0,0], [100,100,0])
# Soft and Smooth are normally set in pairs.
edge.soft = true
edge.smooth = true

Parameters:

  • value (Boolean)

Returns:

  • (Boolean)

def smooth=(value)
end

#smooth? ⇒ Boolean

The #smooth? method is used to retrieve the current smooth setting for an edge.

A smooth edge will cause the shading between connected faces to blend to a smooth transition. The edge will still be visible.

Examples:

edge = Sketchup.active_model.entities.add_line([0,0,0], [100,100,0])
# Soft and Smooth are normally set in pairs.
edge.smooth = !edge.smooth?
edge.soft = edge.smooth?

Returns:

  • (Boolean)

def smooth?
end

#soft=(value) ⇒ Boolean

Note:

The soft and smooth properties are normally set in pairs. You can observer this when the Soften/Smooth Edges feature or holding down Ctrl when using the Eraser Tool.

The #soft= method is used to set the edge to be soft.

A soft edge will cause the connected faces to be treated as a surface. This means that if you have Hidden Geometry off and select one face it will also select all faces connected with soft edges. A soft edge will also appear hidden.

Examples:

edge = Sketchup.active_model.entities.add_line([0,0,0], [100,100,0])
# Soft and Smooth are normally set in pairs.
edge.soft = true
edge.smooth = true

#soft? ⇒ Boolean

The #soft? method is used to retrieve the current smooth setting for an edge.

A soft edge will cause the connected faces to be treated as a surface. This means that if you have Hidden Geometry off and select one face it will also select all faces connected with soft edges. A soft edge will also appear hidden.

Examples:

edge = Sketchup.active_model.entities.add_line([0,0,0], [100,100,0])
# Soft and Smooth are normally set in pairs.
edge.soft = !edge.soft?
edge.smooth = edge.soft?

#split(position) ⇒ Sketchup::Edge

The split method is used to to split an edge into to or more distinct edges. If a Point3d is given, it must be a point that is on the Edge.

If a Float is given, it is a number between 0 and 1 that gives the relative position along the edge at which to split it. For example, edge.split(0.5) will split the Edge at its midpoint. This split position is measured from the Edge.start.

Returns the new Edge that was created as a result of splitting this one.

Examples:

# Split a line in half.
edge = Sketchup.active_model.entities.add_line([0,0,0],[100,100,0])
new_edge = edge.split 0.5

Parameters:

  • position (Geom::Point3d) —

    A Point3d object whose location is along the edge, or a Float between 0.0 and 1.0 defining how far along the edge to split.

Returns:

  • (Sketchup::Edge) —

    the new Edge object that was split off the old one if successful

vertex = edge.start
if (vertex)
  # display a pointer to the Vertex
  UI.messagebox vertex

# Returns a vertex
vertex = edge.start
# Check to see if the edge is used by the Vertex.
