it is possible to add nodes to manipulate the drawing ? on clic event ?
Certainly! When you say "add nodes" I understand that to mean either:
Two.PathIs that what you had in mind?
Objects to the scene
Like Illustrator on clic event

Sorry, just seeing your response now. At the moment there isn't anything out of the box to give you _that_ specific type of functionality... That doesn't mean it's not possible. It's just not written in the library. We could track it as an enhancement though and I will find the time to add an example.
After more thought, I think this would be better as an example in Two.js instead of directly supported in the library. I'll update this ticket once I've made an example.
