サンプルコード

起動　Sketchup.active_model.select_tool LineTool.new

require 'sketchup.rb'



class LineTool
	CURSOR_PENCIL = 632
	def activate
		@mouse_ip = Sketchup::InputPoint.new
		@picked_first_ip = Sketchup::InputPoint.new
		update_ui
	end

	def deactivate(view)
		view.invalidate
	end

	def resume(view)
		update_ui
		view.invalidate
	end

	def suspend(view)
		view.invalidate
	end

	def onCancel(reason, view)
		reset_tool
		view.invalidate
	end

	def onMouseMove(flags, x, y, view)
		if picked_first_point?
			@mouse_ip.pick(view, x, y, @picked_first_ip)
		else
			@mouse_ip.pick(view, x, y)
		end
		view.tooltip = @mouse_ip.tooltip if @mouse_ip.valid?
		view.invalidate
	end

	def onLButtonDown(flags, x, y, view)
		if picked_first_point? && create_edge > 0
			reset_tool
		else
			@picked_first_ip.copy!(@mouse_ip)
		end
		update_ui
		view.invalidate
	end

	def onSetCursor
		UI.set_cursor(CURSOR_PENCIL)
	end

	def draw(view)
		draw_preview(view)
		@mouse_ip.draw(view) if @mouse_ip.display?
	end

	def getExtents
		bounds = Geom::BoundingBox.new
		bounds.add(picked_points)
		bounds
	end

	private

	def update_ui
		if picked_first_point?
			Sketchup.status_text = 'Select end point.'
		else
			Sketchup.status_text = 'Select start point.'
		end
	end

	def reset_tool
		@picked_first_ip.clear
		update_ui
	end

	def picked_first_point?
		@picked_first_ip.valid?
	end

	def picked_points
		points = []
		points << @picked_first_ip.position if picked_first_point?
		points << @mouse_ip.position if @mouse_ip.valid?
		points
	end

	def draw_preview(view)
		points = picked_points
		return unless points.size == 2
		view.set_color_from_line(*points)
		view.line_width = 1
		view.line_stipple = ''
		view.draw(GL_LINES, points)
	end

	def create_edge
		model = Sketchup.active_model
		#model.start_operation('Edge', true)
		edge = model.active_entities.add_line(picked_points)
		num_faces = edge.find_faces || 0
		#model.commit_operation
		num_faces
	end
end

以上。
