**PhotoCAD** is written in Python3 and needs to run on a 64-bit operating system. It is recommended to use Python 3.8 or higher as the interpreter.

Install Python IDE and Python package
-----------------------------------------------------
It is recommended that users use PyCharm as the IDE for **PhotoCAD**, which is available in the free Community Edition of PyCharm. This manual example and software interface is based on PyCharm 2022.2 (Communication Edition) for Windows 11, which can be downloaded from its official website: https://www.jetbrains.com/pycharm

Install PhotoCAD
-------------------------------
Once Python and Pycharm are installed, you can follow the steps in the Quick Start to install and license **fnpcell**. After installation, we will find the completed **fnpcell** and **gpdk** packages in ``Lib>site-packages``. **fnpcell** is the main package of **PhotoCAD**, which is used for parametric layout component scripts and layout routing scripts. **gpdk** is a collection of all parametric layout design scripts in **PhotoCAD**. It contains both component cell layout scripts and other design templates based on parametric component cells.
