Wall Length Adjustment

This is a relatively simple tip, but I was helping a user in the office today and when I adjusted an existing wall using this method, they exclaimed that they didn't know of this functionality....so, just in case you didn't know....

 If you need to adjust the length of an already modeled wall, and one end is going to remain in its original location, select the wall and select the dot at the end that needs to be adjusted holding the left mouse button down, dragging the end of the wall in the direction of the adjustment type in the value of the desired overall length.
