### 07/29/2019
- Was working on 'dsn_python' Python Library.
- Class tree:
~~~
|--dsnwritter.py (top and second level structure)
|--dsn_module.py
|--module class
|--load module functions
|--dsn_rule.py
|--dsn_geo.py
|--boudary class
|--keepout class
|--load drawing functions
|--dsn_net.py
|--net class
|--netclass class
|--load netlist functions
~~~
- Text tree structure is done.
- Documentation and notes for code needed
- Functions are needed to help user use library.
- Function that load `dxf` file
- Function that load `footprint` file
- Function that load `netlist` file
- For board outline/footprint/netlist not loaded from file but define through this library manually, it works very well for now.
- Pull out those information from low-level file and convert it to proper text for `dsn` file
- Record of Tips:
- `Freerouting` cannot take more than one boundary. (error: exact 1 bounding expected)
- Able to use functions to load `dxf` drawings
- "internal cut issue" solved
- Treat every line individually as polygon and labeled as keepout in `dsn` library
- ![](journal_media/keepout_load.png)
- ![](journal_media/dxf_in_freerouting.png)
- TODO: functions that load modules and footprints
