LINE WEIGHTS DEFINED.
Essentially a line weight is the line width you create with your pencil or pen. One line weight makes your drawing look flat, while a variety of line weights will assist in communicating your garden design as a three-dimensional space. Since we are proposing real-life garden spaces, it's important to inject that feeling of depth and clarity to our drawings. It's pretty powerful.
To get started here are a couple of things to consider when exploring line weights:
When looking at a plan view (from the sky down), objects closer to you (like canopy trees) have thicker lines, while elements farthest away (like paving details) are the thinnest.
Another tip is to make any line inside an object thinner than the one on the outside. For instance, make the branching on a plant symbol thinner than the outside circle that surrounds it or brick paver lines would be thinner than the overall line around the patio.
