O que você precisará
The Curvature Pen tool is located under the Pen tool in the Tools panel. Select it, and then select Shape in the tool mode drop-down menu in the Options bar. Then set the Fill and Stroke colors to None.
Note: This only affects a path’s appearance and helps you to visualize the shape better. It has no effect on the stroke — you’ll specify that later when you apply color to the shapes.
Click once on the canvas to start drawing a straight line, and then double-click to add a corner point.
Each double-click creates a straight line between the corner points. Shift-click to constrain your path to 90° and 45° angles.
Press Esc to complete an open path.
Click once to create your first point. Continue tracing around the curved shape, clicking once to place each point.
Click and drag a point to move it — no need to change tools for this.
Click to add extra points for finer control over the curve. It’s easy to delete any extra points — click a point to select it, and then press Delete.
Tip: Each path and shape is automatically saved as a separate shape layer in the Layers panel. Give each shape a unique name to tell it apart. Double-click the layer’s name and type a new one.
It couldn’t be easier to switch between drawing straight lines and curves — just double-click a point to switch between corner and smooth points. You can also double-click a point on a line or shape you’ve already drawn to change it from corner to smooth point and vice versa.
Select a shape layer, or press Shift and click multiple shape layers to color them at once. Change the Fill and Stroke colors in the Options bar.
