## The input geometric model

We start with a geometric model of a 3D object. This is typically a triangle mesh exported from a 3D modeling program.

## Generating the parts

Now we use automatic and interactive methods to subdivide the object into sections. Each section is approximated by a 2D part. Lamina software writes out cutting paths and a PDF file with assembly instructions.

## Construction document

The PDF file documents how to assemble the structure from the parts.

## Building the structure

The parts are plotted and cut out. Then they are attached to each other to build the final object. Various kinds of attachment elements can be generated to make the parts fit together accurately and easily. This paper model was assembled using scotch tape.
