Great software for 2D drawing and sketching and fine for 3D drawing, especially if you are a budget-conscious user. As far as functionality and features go, CorelCAD is a good alternative to AutoCAD. It is much less expensive for a small office or self-employed architect. It does pretty much everything that AutoCAD can do and is fairly easy to learn to use. CorelCAD makes your graphics come to live! Turn visualization into realization on Windows and macOS, thanks to native .DWG file support for efficient collaboration and .STL support for productive 3D publishing.
