Many advanced options are hidden in Photoshop's Brushes palette. By adjusting the spacing we can create a custom brush to make dotted lines. This method uses a path and the paintbrush tool.
Time Required: 2 minutes
- Select the Rectangle tool (U).
- In the options bar click the button for paths.
- Click and drag out a rectangular path in your document.
- Select the paintbrush tool. (B)
- Open the brushes palette if it is not showing. (Window -> Brushes)
- Click on Brush Presets and choose an appropriately-sized, hard, round brush.
- Click on Brush Tip Shape and set the spacing to a number higher than 100%. The preview will give you an idea how the spacing will look.
- While you're in the Brush Tip Shape properties panel, you can also adjust the diameter and hardness if desired.
- Click Scattering in the Brushes Palette and make sure scatter is set to 0%.
- Open the Paths Palette if it is not showing. (Window -> Paths)
- Select the rectangular path you created in step 3.
- Click the "Stroke path with brush" button on the paths palette.
- Any path can be stroked with a brush. Selections can be converted to paths for stroking.
- You can save your custom brush as a preset by choosing New Brush from the brushes palette menu.
- Very small brushes sometimes skip a dot. I don't know why, but you can fill them in by clicking once with the brush in the skipped spot.
- Experiment with shaped brushes and the Scattering options in the brushes palette. There's some powerful stuff hidden in the brushes palette!
