The ability to use it as an add-on for other CAD applications is great! I have used this software in conjunction with Solidworks (DWG) files. It has made creating my models much easier than if i was using only DWGs. This program does not do well when working in higher resolutions (4800x1200). If resolution isn't set correctly, it will start making lines that are too wide/thin causing many problems throughout your model. My favorite feature of keysoft landscape is being able to utilize different types of file formats such as dwg, dxf etc.
