Torus (Donut)

Okay this time around I’m not dealing with donut faces I’m actually trying to create a donut or more properly a torus with two circles and the followme method. Has anyone tried this before?

Donut example:

github.com

SketchUp/sketchup-ruby-api-tutorials/blob/main/examples/99_hello_donut/ex_hello_donut/main.rb#L9-L29


      
          def self.create_donut
            model = Sketchup.active_model
            model.start_operation('Create Donut', true)
            group = model.active_entities.add_group
            # Create a filled circle which later will be extruded along a path to
            # create a donut shape.
            num_segments = 24
            center_radius = 1.m
            thickness = 0.5.m
            origin = Geom::Point3d.new(0, center_radius, 0)
            circle = group.entities.add_circle(origin, X_AXIS, thickness, num_segments)
            face = group.entities.add_face(circle)
            # Create a temporary path for follow me to use to perform the revolve.
            # This path should not touch the face.
            path = group.entities.add_circle(ORIGIN, Z_AXIS, center_radius, num_segments)
            # This creates the donut.
            face.followme(path)
            # The temporary path is no longer needed.
            # group.entities.erase_entities(path)
            model.commit_operation
          end

I sent you code using arcs [for more control] last time you asked?

For some reason I thought this would be hard, here is my code:

        barradius = @Hbardia * 0.5

		xpos = @Pierdia * 0.5 - rebarclr
		ypos = 0
		zpos = 0 - rebarclr - 1.0
		
		grouph = Sketchup.active_model.active_entities.add_group
		entitiesh = grouph.entities

		centertorus = Geom::Point3d.new 0, 0, zpos
		torusradius = xpos
		toruscircle = entitiesh.add_circle centertorus, Z_AXIS, torusradius, 24

		group2 = Sketchup.active_model.active_entities.add_group
		entities2 = group2.entities

		centercircle = Geom::Point3d.new xpos, ypos, zpos
		barcircle = entities2.add_circle centercircle, Y_AXIS, barradius, @Numsegs_db
		barface = entities2.add_face(barcircle)
	
		barface.followme(toruscircle)
		grouph.erase!

Too easy!
