week 2 Finding out the real silhouette of the lake

I want on the internet to find out the real size and silhouette of the lake
I used Google Maps to copy the structure of the lake/water and looked for a program to make an pdf file to Print/Laser this structure out.

When i found out i could use Autocad for this, i made the structure as big as an A1 paper.

I wanted to make a wood structure of the lake with the trees as wood sticks.
