Overview

Drawingelement is a base class for an item in the model that can be displayed. These items include edges, construction points, construction lines, and images. Arc curves and arcs are not included because they are not drawing elements by themselves, but are a composition of edges.

Instance Method Details

#bounds ⇒ Geom::BoundingBox

The bounds method is used to retrieve the BoundingBox for an drawing element.

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
# Remember, anything that can be displayed, such as a face, is also
# a Drawingelement. So I can call bounds on a face because Face
# is a sub-class of Drawingelement.
boundingbox = face.bounds

Returns:

#casts_shadows=(casts) ⇒ Boolean

The casts_shadows= method is used to set the Drawingelement to cast shadows.

Examples:

depth = 100
width = 100
model = Sketchup.active_model
entities = model.active_entities
pts = []
pts[0] = [0, 0, 100]

pts[2] = [width, depth, 100]
pts[3] = [0, depth, 100]
# Add the face to the entities in the model.
face = entities.add_face pts

# Make the face not cast shadows.
status = face.casts_shadows = false
UI.messagebox status.to_s

Parameters:

  • casts (Boolean) —

    true if you want the Drawingelement object to cast shadows, false if you do not want the Drawingelement object to cast shadows.

Returns:

face = entities.add_face pts
UI.messagebox "Click OK to Hide the Box"
status = face.hidden = true

width = 100
model = Sketchup.active_model
entities = model.active_entities
pts = []
pts[0] = [0, 0, 0]

#layer=(layer) ⇒ Sketchup::Layer, String

The layer= method is used to set the layer for the drawing element.

An exception is raised if you give a string that doesn’t match any layer name.

Examples:

depth = 100
width = 100
model = Sketchup.active_model
entities = model.active_entities
pts = []
pts[0] = [0, 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 a layer
layer = Sketchup.active_model.layers.add "joe"
# Put the face on the joe layer (instead of layer 0)
newlayer = face.layer = layer
