Ok, i send you a blank file with different shapes made by the plugin in this link : https://dl.dropbox.com/u/82810005/2dlinesTest.skp
When i select a shape (directly or selecting one line an then "select all conected") i am unable to push/ pull. Any help is greatly appreciated. My sketchup is v. 8.0.1515.

It could be any number of problems and most likely something you are doing. Without an example, it is difficult to say. If I had to guess, I'd say you didn't have any face to extrude. You could post the SKP file so we'd have some hope of helping you.

Hello!!

This seems like a great tool. However i was having difficulties to extrude / push the 2d area made by the plugin, is it my mistake or it is impossible??
Is there any wasy way to draw on a locked 2d plane and then be able to extrude this area??

Thanks in advance
