The Packet Tree

A single Regina data file can store a range of objects, from 3-manifold triangulations and normal surfaces to Python scripts, PDF documents and text notes. All of these objects are called packets, and are arranged in a tree-like structure as you can see below.

To view or edit a packet, just click on the packet in the tree (on some platforms, such as MacOS X, you need to double-click instead). The packet will open up in the right-hand side of the window, as shown below.
