# LibreCAD/LibreCAD

LibreCAD is a cross-platform 2D CAD program. It can read DXF/DWG, and write DXF/DWG/PDF/SVG files. It supports point/line/circle/ellipse/parabola/hyperbola/spline primitives. The GUI is highly customizable, and has dozens of translations.

## What it is
LibreCAD is a free, open-source, cross-platform 2D CAD application built on Qt, based on the QCAD community edition. It reads and writes DXF/DWG, exports PDF/SVG/PNG, supports standard 2D geometry primitives, and can also run as a DXF converter from the command line.

## Use cases
- draw 2D technical plans and blueprints
- open and edit DXF or DWG files for free
- convert DXF files to PDF, PNG, or SVG
- import ESRI shapefiles into a CAD drawing
- free AutoCAD alternative for Windows, Mac, and Linux
- create 2D geometry with lines, circles, splines, and ellipses

## When to choose
- you need a free, no-subscription 2D CAD tool
- you work with DXF/DWG files across Linux, macOS, and Windows
- you want scriptable DXF-to-PDF/SVG/PNG conversion
- you need a localized UI in one of 30+ languages

## When to avoid
- you need 3D modeling or parametric feature-based CAD
- you require notarized macOS builds or commercial support
- you need Shapefile export (import is read-only)

## Facets
- artifact type: application
- maturity: active
- function: gui, file-system, graphics
- domain: cross-platform, developer-tools, graphics
- platform: windows, cpp, cross-platform
- tags: cad, 2d-drawing, dxf, dwg, qt, svg-export, pdf-export, shapefile-import, open-source, linux, macos, desktop
