I am new to concepts 2D but many (many more than I care to think about) years ago used an early version of Acad. I still remember some of how Acad worked. I am using the line command and know there must be an easier way to do what I am trying. Is it possible to call out a line by angle and/or length without first drawing a line and then editing it? What is the easy way to draw a line .105 long @ 270 degrees, from that another line 3.5 long @ 0 degrees, another from that at .325 long @ 90 degrees and then to close the box. Acad you just pushed "c" for close to do this.
I know there has to be a lot easier way to do this than I have found so far. Thanks for any help.

There is a 'dynamic help' which is html based. Not very well presented but you can get it by pressing the '?' on the top line of the current tool you're in - not sure if that helps.
