This is an open-source utility dedicated to generating 3D models of Printed Circuit Boards (PCBs) in Blender (.blend) format. The tool uses Gerber (Gerber RS-274X) input files that are used for producing physical PCBs. This makes the PCB visualization independent from the software used for designing it. Currently gerber2blend supports Blender 4.5+.

Installation

Requirements

gerber2blend depends on the following packages:

  • gerbv (recommended >=2.10)
  • inkscape >= 1.2
  • python3.11, pipx

Additionally to preview and modify the generated .blend file Blender 4.5 LTS needs to be installed.

Installation (Debian)

  1. Install the dependencies:

    sudo apt-get update
sudo apt install gerbv inkscape python3.11 python3.11-venv pipx

  2. Configure PATH:

    export PATH=$HOME/.local/bin:$PATH

  3. Clone and install gerber2blend:

    python3.11 -m pipx install 'git+https://github.com/antmicro/gerber2blend.git'

Usage

Please check the gerber2blend documentation for more guidelines.

glTF generation

gerber2blend supports exporting PCB model to glTF format. To use that functionality you need KTX-Software and gltf-transform npm package in version 4.2.0 installed:

wget https://github.com/KhronosGroup/KTX-Software/releases/download/v4.4.0/KTX-Software-4.4.0-Linux-x86_64.deb
sudo dpkg --install KTX-Software-4.4.0-Linux-x86_64.deb
sudo apt install npm
nvm use 22
npm install -g @gltf-transform/cli@4.2.0 @gltf-transform/core@4.2.0 @gltf-transform/extensions@4.2.0 @gltf-transform/functions@4.2.0

`gltf-transform` requires Node version >= 22.
