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 works 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.
