Overview

LibreCAD is a 2D CAD application for creating orthogonal and isometric projections, including technical drawings and floor plans. It supports viewing and editing DWG and DXF files, with export options to DXF and SVG formats. Designed for users needing precise 2D drafting, it stands out with layer support for organizing drawings and command-line input for accurate coordinate entry.32

Key Features

  • Layers - Organizes drawings by grouping entities with common attributes, such as walls or electrical elements in floor plans.3
  • Command Line - Provides keyboard-based tool selection, coordinate entry, calculator functions, and multi-command input for precision.6
  • Orthogonal Projections - Supports creation of standard 2D technical drawings.3
  • Isometric Projections - Enables 2.5D representation of 3D models in 2D views.3
  • DWG/DXF Support - Views and saves in DXF format; compatible with DWG files.3
  • Customizable Interface - Allows modification of menus, toolbars, widgets, and style sheets.5
  • Templates - Uses default or user-defined templates for new drawings, set via application preferences.4
  • Snap Tools - Offers snapping options for accurate drawing placement.10

Reputation

LibreCAD is regarded as a reliable free 2D CAD tool for basic drafting and viewing DXF/DWG files, praised for layer support and command-line precision.36 Users appreciate its cross-platform availability and open-source nature under GPLv2.3 Criticisms include incomplete documentation and lack of advanced 3D features, with ongoing community development.13
