if you find another layer let me know, because one of the reasons we've spent has been for that work.Not to mention that on numerous occasions the browser congealed and I had to restart losing all work done, in other words, I would have been much better if all the possibilities of the DA-Wall.But hey, were clear that out in this way, so do not think you can do anything about it, at the end I had to find a way to easily make the drawing not to entangle the work one more time.
