Removing several anchor points in a path quickly -using a box for example- (Illustrator CC)?

Question

If I have an anchor points path of a deformed box, and I want to remove all the points except the base (the bottom line), is it possible to remove them quickly? maybe using a box selection, is it possible the box selection causes the path to move

Answer 1

With the lasso tool (shortcut Q) you can quickly select the anchor points you want to delete, when selected you can press the delete key to delete the anchors.
