KiCAD_Utilities

MATLAB or Python functions/scripts to help with things like electrode coordinate placement etc. on PCB layouts in KiCAD specifically.

Features

• Extract coordinates from DXF files: Parse circular elements (electrodes, mounting holes) from CAD drawings
• Interactive GUI: File dialogs and element selection for easy workflow
• Update KiCad PCB files: Automatically update footprint locations based on DXF coordinates
• Coordinate transformations: Apply offsets, flipping, and centering based on PCB schematic style
• Flexible element mapping: Supports multiple element types with configurable metadata

Python Usage

Interactive Mode (Recommended)

Run the script and follow the GUI prompts:

cd python
python example_update_pcb_from_dxf.py

The script will guide you through:

1. Selecting a DXF file
2. Selecting a KiCad PCB file
3. Choosing which circular elements to update
4. Configuring coordinate transformations
5. Updating the PCB file

Requirements

pip install -r python/requirements.txt

Required packages:

• ezdxf
• numpy
• pandas
• matplotlib
