Can the Ruby API monitor the consumer’s actions drawn by the drawing instrument? – Ruby API

Can the Ruby API monitor the consumer’s actions in drawing faces with the drawing instrument? Every time the consumer attracts a floor get the coordinate info of that floor.

I discovered the related code, however I don’t know how you can management MyEntitiesObserver to run or cease. I might recognize any recommendation, thanks!

class MyEntitiesObserver < Sketchup::EntitiesObserver
  def onElementAdded(entities, entity)
    places "onElementAdded: #{entity}"
    if entity.typename == "Face" 
      p entity.persistent_id
    finish
  finish
finish

# Connect the observer
Sketchup.active_model.entities.add_observer(MyEntitiesObserver.new)

See the instance right here
Entities #remove_observer-instance_method

By the best way:
entity.typename == "Face" compassion is sluggish, use entity.is_a?(Sketchup::Face) as a substitute.
