AutoCAD vs LibreCAD

AutoCAD is software for precise 2D and 3D drafting, design, and modeling. It uses DWG as its primary file format and also supports DXF and PDF underlays. Seven specialized toolsets address architecture, mechanical, MEP, electrical, plant, mapping, and raster design. Teams can share DWG files, work in parallel, and add markups with multiple users. AI capabilities include markup assistance, block replacement suggestions, and contextual productivity tips. Standalone subscriptions include Forma Data Management Essentials. AutoCAD runs on Windows, macOS, web, iOS, and Android; subscriptions include web and mobile access. Each subscription is assigned to one named user and can be installed on up to three devices, with use limited to one device at a time. A 15-day free trial is available. Pricing starts at $175 per month; listed options are $260 per month or $2,095 per year. Eligible students and educators can receive renewable one-year access while eligible.

LibreCAD is a free, open-source 2D CAD application released under the GNU General Public License version 2. Its drawing tools include lines, circles, arcs, polylines and splines, along with entity modification, hatching, blocks, annotations and dimensions. DXF is its main format, with import and export; it can also export PDF and images and import DWG on a limited basis. The FAQ describes DWG support as basic and import-only, and suggests converting DWG to DXF if import fails. LibreCAD does not support every Autodesk DXF feature, and lists support for versions R12, R14, 2000, 2004 and 2007. The interface is available in over 30 languages, and the application runs on Linux, macOS and Windows. Community-developed plugins can help with some tasks. The project describes itself as non-profit and community-driven, with free support and documentation from its community. The software is free, with no trial, subscription, license cost or annual fee. It is distributed without warranty, including implied warranties of merchantability or fitness for a particular purpose.
