I need to create a tube with all sides (also the inner part) being red. Here is my code:
model = Sketchup.active_model
entities = model.entities
tubeOuterWidth = 10.5
tubeInnerWidth = 7
#Draw smal circle
edges2 = entities.add_circle [0,0,10],[0,0,-10],(tubeInnerWidth / 2)
curve2 = edges2[0].curve
face2 = entities.add_face(curve2)
#Draw bigger circle
edges1 = entities.add_circle [0,0,0],[0,0,10],(tubeOuterWidth / 2)
curve1 = edges1[0].curve
face1 = entities.add_face(curve1)
#Make 3D tube
face1.pushpull( -10 )
face2.pushpull( 10 )
#Color all faces red, also the top and inner part of the tube!!!!!!!!!!
faces = Sketchup.active_model.entities.grep(Sketchup::Face).find_all { |f| !f.deleted? }
faces.each do |face3|
face3.material = 'Red'
end
The outcome is that the bottom and round part of the outer cilinder is red, but the top and inner part not? I am new to SketchUp and Ruby and don’t know why this does not do what I want.
You were almost correct, but your statements were a bit out of order …
def make_tube(
outer_width = 10.5,
inner_width = 7
)
#
model = Sketchup.active_model
model.start_operation('Draw Tube', true)
#
editing_context = model.active_entities
# Create a group context:
group = editing_context.add_group
entities = group.entities
# Draw outer circle:
edges_outer = entities.add_circle( ORIGIN, Z_AXIS, (outer_width / 2) )
# Make the bottom face:
curve_outer = edges_outer.first.curve
entities.add_face(curve_outer)
# Draw inner circle (which divides the bottom face into 2 faces):
edges_inner = entities.add_circle( ORIGIN, Z_AXIS, (inner_width / 2) )
# Get the outer face, which is that common to an outer edge and an inner edge:
outer_face = edges_outer[0].common_face(edges_inner[0])
# Get the faces set for the smaller circle (ie, both faces):
both_faces = edges_inner[0].faces
# Subtract an array of the outer face from the faces array, getting the remaining face:
inner_face = ( both_faces - [outer_face] ).first
# Erase the inner face:
inner_face.erase!
# Faces drawn with the API upon the ground plane are facing down, so ...
outer_face.reverse!
# Color the face:
outer_face.material = 'Red'
# Make 3D tube:
outer_face.pushpull( 10 )
#
model.commit_operation
#
return group
end
Thanks for your solution, but it did not work for me. In the Ruby console I get below message and no tube:
Running the code...
Done running code. Ruby says: make_tube
But after playing with your code and changing it, I got a script that does work for me:
outer_width = 10.5
inner_width = 7
# Draw outer circle:
edges_outer = entities.add_circle( ORIGIN, Z_AXIS, (outer_width / 2) )
# Make the bottom face:
curve_outer = edges_outer.first.curve
entities.add_face(curve_outer)
# Draw inner circle (which divides the bottom face into 2 faces):
edges_inner = entities.add_circle( ORIGIN, Z_AXIS, (inner_width / 2) )
# Get the outer face, which is that common to an outer edge and an inner edge:
outer_face = edges_outer[0].common_face(edges_inner[0])
# Get the faces set for the smaller circle (ie, both faces):
both_faces = edges_inner[0].faces
# Subtract an array of the outer face from the faces array, getting the remaining face:
inner_face = ( both_faces - [outer_face] ).first
# Erase the inner face:
inner_face.erase!
# Faces drawn with the API upon the ground plane are facing down, so ...
outer_face.reverse!
# Color the face:
outer_face.material = 'Red'
# Make 3D tube:
outer_face.pushpull( 10 )
So thanks again for your effort and I don’t understand why your code didn’t work for me or my first code, but I am happy I have a working script now.
