Abstract

This chapter explains how to use projects to make your work persistent. We will explain how to create new projects, how to add or remove data from the project and how to save and reopen project files.

## What is a project

A pyFormex project is a persistent copy of some data created by pyFormex. These data are saved in a project file, which you can later re-open to import the data in another pyFormex session.
