In Flow, you create a set of drawing tools that can each be customized. You can choose a style, color and size for each tool. With Apple Pencil the tools react to tilt and pressure.
Tools are created and organized in the Tool Dock. When you want to change a tool’s properties like color, tip, or size, this is done in the Tool Editor, which always displays information for the tool you currently have selected.
Below is a brief explanation of each of the seven tool types offered in Flow:
A brush style pen that applies on top of your existing drawing at full opacity. A highly variable size that can be controlled by pressure with an Apple Pencil makes it ideal for inking large areas.
A technical style pencil with a balanced mix of softness, sharpness and texture. The size is slightly responsive to pressure and can be used for shading at an angle. Applies additively so you can build up strokes or use it for marking-up.
A smooth, roller style pen that applies at full opacity and builds additively. The size changes minimally with speed and pressure, so it’s ideal for note taking or precise drawing where clean lines are desired.
An expressive pen with smooth ink flow and highly variable size depending on speed, pressure and the angle you are holding an Apple Pencil.
A round tipped marker. The opacity will build with each individual stroke you make by lifting the Brush or your finger and drawing again.
A chisel tipped marker that responds to the angle you are holding an Apple Pencil. The opacity will build with each individual stroke you make as you lift off the screen and draw again.
Applies over large areas with additive blending and responds to pressure.
The Eraser tool is found at the top of the Tool Dock. When selected, it slides out in a similar fashion to the drawing tools and has two modes it can be used in.
Normal mode – In normal mode, the eraser can be drawn with remove like a traditional eraser. You can choose size and a hard or soft edge.
Stroke mode – Flow’s stroke eraser removes entire strokes as you touch them. You can toggle which types of tool the eraser will be able to delete.
To clear the entire document, press and hold on the eraser until the dialogue box appears.
