windows11で、sketchup6 その47

概要

windows11に、sketchup6を入れてみた。
rubyで、3Dを書く。
プラグインのサンプル見つけたので、やってみた。

サンプルコード

require 'sketchup.rb'

module Examples
	module CustomTool
		class LineTool
			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
			CURSOR_PENCIL = 632
			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
		def self.activate_line_tool
			UI.messagebox "ok"
			Sketchup.active_model.select_tool(LineTool.new)
		end
		unless file_loaded?(__FILE__)
			menu = UI.menu('Plugins')
			menu.add_item('Line Tool') {
				self.activate_line_tool
			}
			file_loaded(__FILE__)
		end
	end
end

以上。
