Creating panels for placing Blender add-ons user interface (UI)

One of the essential conditions of comfortable work is the convenience and speed of accessing add-ons functional. It is not enough to write an add-on and register it in Blender API system. Be sure to give the easy call add-on functions ability to the user. So, any add-on should determine a place to put interface buttons that provide access to its functionality.

This tutorial is for Blender 2.79 and older. For the last Blender versions, please see this tutorial.

All available Blender user interface located on panels. Three panels are the most used: T-bar – opens/hides by pressing the t keyboard button, N-bar – opens/hides by pressing the n button, and the Properties panel – called in the main menu of any window, typed it as Properties.

Blender API allows defining users panels to place add-on functional buttons on any of these three main panels.
