LibreCAD Overview
LibreCAD is a free, open-source 2D computer-aided design (CAD) application for Windows, macOS, and Linux, suited to technical drawing, floor plans, schematics, and other precise 2D drafting. It provides the core drafting tools — lines, arcs, circles, polylines, dimensioning, layers, and blocks — with snapping and precise coordinate entry for accurate work. Its native format is the widely used DXF, and it can also import and export other 2D formats, which makes it compatible with many CAD workflows. It is a lightweight, focused free alternative for 2D drafting. The full LibreCAD installer is self-contained and finishes installation even on an offline machine. It is based on the older QCad codebase and keeps a small, focused toolset, which makes it quick to learn for straightforward 2D drafting and for editing existing DXF drawings without a heavy CAD suite.
