# Introduction/Overview

## Program Goals

RDPharm3D is a computational tool that allows scientists who are not computational experts to quickly and easily ask -- and answer -- "what if?" type questions using pharmacophore models. The models themselves are developed by computational chemists and deployed to the end-user scientists. End users query the pharmacophore models by simply drawing probe molecules in ChemDraw and then pulling them into RDPharm3D with a button click.
