Set the compass to the first measurement you took from the house. Put the point where you measured from on the house, and draw an arc.
Reset the compass to the second measurement. Put the point where you measured from on the house, and draw a second arc to cross the first.
Repeat Steps 1 and 2 for all of your boundary triangulation measurements. Connect the center points of each of the crosses to plot your boundary.
Using the same technique outlined in Steps 1 to 3, plot the position of buildings, trees, plants, and other major features to create your scale plan.
