## What it is
QCAD is an open source 2D CAD application for creating technical drawings such as building plans, mechanical parts, and schematics, built in C++ on Qt. It supports DXF (and optionally DWG via a proprietary plugin), offers a JavaScript scripting interface, command-line conversion tools, and an extensible plugin architecture.

## Use cases
- create 2D technical drawings and floor plans
- convert DWG files to PDF, SVG, or BMP from the command line
- edit and view DXF files on Linux, Windows, or macOS
- automate CAD drawing tasks with ECMAScript scripting
- export G-Code for CNC machining with QCAD/CAM
- draw mechanical parts and schematics without expensive CAD licenses

## When to choose
- you need a free, cross-platform 2D CAD tool with strong DXF support
- you want scriptable or command-line CAD file conversion
- you need an extensible CAD system with plugin and scripting APIs
- you are a beginner looking for an intuitive 2D drafting application

## When to avoid
- you need full 3D modeling capabilities
- you require native DWG support without a proprietary plugin
- you need parametric feature-based CAD like FreeCAD provides

## Facets
- artifact type: application
- maturity: stable
- function: gui, cli, file-system, graphics, plugin-system
- domain: cross-platform, desktop-applications, developer-tools
- platform: windows, cpp, cli
