It's highly popular for enterprise line of business and industrial apps you'll never hear about. Some of it is moving to web but web is not really competitive in terms of performance and integration (lots of legacy COM/ActiveX or closed source native libraries to integrate with). The only realistic alternative is using WinForms (more dead than WPF) or Qt but then you have to hire C++ programmers. It's certainly perfomant enough (much faster than web) for complex apps like CAD - the actual editor/renderer won't be WPF of course but some custom OpenGL/Direct3D code.
