Why the Pen tool matters
The Pen tool gives you full control over every anchor and handle in a path. Once it clicks, you can vectorize anything — logos, icons, illustration linework — with curves smoother than any other tool can produce.
Anchor points and handles
Each anchor is either a corner point (no handles, sharp angle) or a smooth point (two handles that control the curve's direction and length). Handles are tangent to the curve — longer handles mean broader, softer curves.
Drawing your first curve
Press P, click once to drop an anchor, then click-and-drag at the next position. The dragged distance becomes the outgoing handle. Repeat. Aim for the fewest anchors possible — every extra point adds wobble.
Corner-to-smooth transitions
Hold Alt and drag a handle to change a smooth point into a corner with an independent outgoing direction. This is how you draw a leaf — smooth on top, sharp at the tip.
Following a reference
Place a sketch on a locked layer at 30% opacity. Trace by setting anchors at the extremes of each curve — top, bottom, left, right of a circle, not in between. Your paths will be cleaner than any auto-trace.
Curvature Tool
Press Shift+~ for the Curvature Tool — click along a path and Illustrator interpolates smooth curves. Great for beginners, but the classic Pen still wins for tight, deliberate control.
Editing existing paths
Direct Selection (A) selects individual anchors and handles. Hold Cmd/Ctrl to temporarily switch from Pen to last selection tool — move an anchor and continue drawing without breaking flow.
Practice drill
Trace the alphabet in a single weight. The mix of curves, corners and tight inner radii in letters like B, S and R forces you through every Pen scenario in two evenings.
