A ready-made basic shape, such as a cube, sphere or cylinder, to start from

Also called Mesh primitive

What is a primitive in 3D modeling?

A primitive is a ready-made basic shape that 3D software adds in one click, such as a cube, sphere, cylinder, cone, plane or torus. Most models start as a primitive that is then extruded, cut and reshaped. You can usually set its size and number of segments as you add it.

Think of it like this

Primitives are like the basic blocks in a toy set: a cube, a cylinder and a ball can be stacked and carved into almost anything.

How a primitive works

  1. 01Add a primitive close to the shape you want, such as a cylinder for a cup.
  2. 02Set its size and number of segments before you edit it.
  3. 03Reshape it with extrude, loop cuts and moved vertices.
  4. 04Combine several primitives for more complex objects.

Where a primitive is used

  • The starting shape for almost any hard-surface model
  • Quick stand-ins for blocking out a scene
  • Cutters for boolean operations

Beginner tip

Pick the primitive whose layout matches your target. A cylinder already has loops running around it, which suits a bottle better than reshaping a cube would.

Primitive FAQ

What are the basic 3D primitives?
The usual set is the plane, cube, sphere, cylinder, cone and torus, a ring shaped like a doughnut. Blender also adds a circle, a grid and a monkey head that people use for test renders.
How do I add a primitive in Blender?
Press Shift+A in the viewport, choose Mesh, then pick a shape. It appears at the 3D cursor, and the panel in the lower-left corner lets you change its size and segments right away.
UV sphere vs ico sphere: which should I use?
A UV sphere has rows and columns like a globe, with pinch points at the top and bottom, which suits planets and anything you will unwrap. An ico sphere is made of even triangles, which suits sculpting and evenly spread detail.
