You can resize or reshape a site boundary by clicking and dragging its grab handles.
To stretch a site boundary:
Click on one of your lot lines to select the site boundary. If you want to resize the boundary, click on the specific lot line that you want to move. Clear blue grab handles appear at each corner of the boundary, and a solid blue grab handle appears at the center of the lot line you selected.
To resize the boundary, click and drag the solid blue grab handle. To reshape the boundary, click and drag one of the clear blue corner grab handles.
Release your mouse button.
Note: You can also edit the length and direction of individual lot lines precisely by editing the boundary’s properties.
