Bezier curve

A smooth curve shaped by a few anchor points and the handles that pull on them

Also called Bézier curve, Bezier path

What is a Bezier curve?

A Bezier curve is a smooth line defined by anchor points and handles. The curve passes through each anchor, and each handle sets the direction and pull of the curve as it leaves that point. In 3D apps, Bezier curves draw paths, cables, logos and outlines.

Think of it like this

Picture a garden hose held at a few spots. Where your hands grip it are the anchors; the way you point each wrist is a handle.

How a Bezier curve works

  1. 01Click to place anchor points where the curve should pass.
  2. 02Drag each anchor’s handles to set how sharply the curve bends.
  3. 03The software draws a smooth line between anchors from those settings.
  4. 04Give the curve depth or a profile shape to turn it into a 3D object.

Bezier curve vs NURBS

Common inPaths, logos, motion graphics, cablesCar, product and CAD design

Use Bezier curves for paths, outlines and shapes you draw by hand; use NURBS when a product needs precise, smooth surfaces.

Where a Bezier curve is used

  • Camera and animation paths through a scene
  • Cables, pipes and ropes given thickness along a line
  • Logos and text outlines turned into 3D shapes

Beginner tip

Use as few anchors as you can. Two anchors with well-placed handles make a cleaner arc than six anchors pulling against each other.

Bezier curve FAQ

What are Bezier handles?
The two arms that stick out of each anchor point. Their direction sets which way the curve leaves the point, and their length sets how far it travels before turning. Short handles make tight bends; long ones make wide, gentle arcs.
Is a Bezier curve the same as a spline?
A Bezier curve is one type of spline. Spline is the general word for a smooth curve built from control points, and Bezier is the type most drawing and 3D apps use for hand-drawn paths.
How do I turn a Bezier curve into a mesh?
Give it thickness first, with a bevel depth or a profile shape in the curve’s settings, then convert it. In Blender, Object > Convert > Mesh does this. The result is ordinary geometry you can edit.
