QCAD is a free computer-aided design (CAD) software application for 2D design and drafting. It is available for Linux, Apple macOS, Unix and Microsoft Windows. The QCAD GUI is based on the Qt framework.
Some of the interface and concepts behind QCAD are similar to those of AutoCAD.
Starting from version 3.7 QCAD is distributed as Professional Trial that work for a limited time, or as Community Edition as source code only, so users need to self compile or remove the QCAD Professional add-on running in trial mode.
QCAD operates on Linux, macOS [10.7 (Lion) or later], UNIX (FreeBSD, NetBSD), Solaris for x86 and SPARC, and Windows [8, 7, Vista, XP, 2000]. This is of importance for collaboration across a diverse computing environment.
