You sound like me! I have an associates in Computer-Aided Drafting. Love designing. Download DraftSight Its Free! :). Go to Office Max, Office Depot, Staples!, buy an architects scale, in order to draw out rooms on paper. Also when you save your dwg files, act like your printing and select print to pdf. You can take a jump drive to Fedex Office, and they'll print it out for you.
Keys to Remember:
Think Green! Think Modular! Think Even Measurements!
Use 4'x4' grids (Frank Lloyd Wright Method) to layout rooms at a 1/4"=1'-0" or 1/8"=1'-0" scale.
In order to save on wood make sure all studs, floor, and ceiling joist are 2' or 24" on center instead of 1'-4" or 16" on center.
Room Size to start:
20' wide by 24' long (extra space): Garage, Gathering, Great Rm, Keeping Rm, Hearth, Bonus
16' wide by 20' long (ample space): Master Bedroom, Kitchen, Living, Dining, Outdoor Living.
