Chaining walls together

[Brian J. Larson]

Max,

I know how to draw walls by clicking the left mouse button 50 million times. I want to be able to left click once pull my mouse in a specific direction, enter a specific distance hit return and my first wall is placed. Then another wall automatically starts from the endpoint of the first wall and you enter in your specific distance in a specific direction, hit return and you second wall is placed.(and so on , and so on)
This way you place your wall at the exact length in the direction you specify.
There should be a smarter way.

Thanks,
