3D Shape Net Generator

Describe any 3D shape — AI unfolds it into a flat net with exact dimensions

This AI-powered net generator creates unfolded diagrams (nets) for any 3D shape. Type a shape with dimensions — like "cylinder radius 3 height 5" or "regular tetrahedron side 4" — and the AI draws the complete flat pattern with fold lines, dimension labels, and surface area.

Works for cylinders, cones, cubes, rectangular prisms, triangular prisms, pyramids, tetrahedra, octahedra, and more. Every net uses precise measurements — what you see is what you can print and fold.

Unlike static net galleries, this tool handles any dimensions you specify. Ask the AI to explain the math: "Why is the cone sector angle 120°?" or "What's the surface area of this prism?"

FAQ

What is a net of a 3D shape?
A net is a flat 2D pattern that folds into a 3D shape. For example, a cube net is six connected squares, and a cylinder net is a rectangle (the lateral surface) plus two circles (the top and bottom bases).
How do I calculate the cone net sector angle?
For a cone with base radius r and slant height l, the sector angle is θ = (r/l) × 360°. The sector's radius equals the slant height, and its arc length equals the base circumference 2πr.
What is the surface area of a cylinder?
Total surface area = 2πr² + 2πrh. The first term is the two circular bases, the second is the lateral surface (a rectangle with width 2πr and height h when unfolded).
Can I print these nets?
Yes! The dimensions shown are mathematically exact. Use the share/export button to save the net, then print at any scale. For physical models, remember to add small tabs along fold lines for gluing.
What shapes can this tool generate?
Any polyhedron or surface of revolution: cubes, rectangular prisms, cylinders, cones, pyramids, triangular prisms, tetrahedra, octahedra, and custom shapes. Just describe the shape and its dimensions.
