The plans

The plans show a flat plan "bird's-eye view" and an elevation (side) plan giving all dimensions. Refer to these plans for any required measurements throughout the project.

Setting out

The carport is a 6000 mm x 3000mm (20ft x 10ft) rectangle.
Mark out the four corners, and erect wood profile boards (batter boards) out from each corner and also out from the middle to take in the two center posts. Set the profile boards (batter boards) back at least 600mm (2ft) from the building line (carport perimeter) to allow room for hole digging etc.
For instructions on setting the profiles go to http://www.buildeazy.com/plans/helpfiles_profile.html

The building line (in this case) is the perimeter of the carport (the very outside edge). It is a 6000 mm x 3000mm (20ft x 10ft) rectangle.
The posts however, will need to be off-set in from the building line, 50mm (2") in from the sides and 300mm (12") back from each end (front and back).
Use string lines (attached to the batter boards) to make a rectangle that will determine the post positions.
As mentioned, the posts will be off-set 50mm (2") in from the sides of the building line, and 300mm (12") back from the ends (front and back) of the building line,
thus, the stringline should form a rectangle 5400mm x 2900mm (18ft x 9ft-8in).
