Scheme Cad: Open-Source 2D & 3D CAD Software for Electrical Design
Scheme Cad is an open-source 2D and 3D CAD software application created specifically for schematic drawing and electrical design. It provides powerful tools for circuit diagram creation, PCB layout design, simulation and more.
What is Scheme Cad?
Scheme Cad is an open-source, cross-platform CAD software application designed for electrical engineers, designers, makers and hobbyists to create schematic diagrams and PCB layouts. It offers an intuitive and customizable user interface with support for both 2D drafting and basic 3D modeling capabilities.
Key features of Scheme Cad include:
- Intuitive schematic capture tools for drawing circuit diagrams with component libraries for common parts and symbols
- PCB layout tools for designing 2-layer printed circuit boards
- Drag-and-drop interface for placing components and routing connections
- Support for SPICE netlist generation and analog/digital circuit simulation
- Import/export capabilities for various CAD file formats and standards
- Parametric drawing and reusable component creation tools
- 3D modeling for basic enclosure design and PCB preview visualization
As an open-source software, Scheme Cad benefits from continuous community development and platform support across Windows, Mac, and Linux. It offers an affordable, accessible CAD solution for DIY electrical/electronic designs and prototyping projects, though it lacks some advanced capabilities of proprietary tools like Altium Designer or Eagle.
