# Introduction

PADS4 Designer provides a **wide range of built-in page elements** to create professional presentations. Each element type has **specific properties**, along with **common properties** shared by all elements.

In addition to built-in elements, **Add-On elements** can be installed and used just like standard elements, offering extended functionality.
