I like that it is easy to drag and drop models and orient them in PreForm. It is also easy to add support structures with the magic wand tool and visualize how the print will appear on the bed. It also allows for many different ways to customize the support structures and how the printer builds the layers. It also highlights areas where the build might fail, such as overhangs or intersecting models. There are many significant updates for the newest version, such as many more custom options for the rafts.

User-friendliness is great, and the auto-support features are handy too.

The intuitive nature of how to use it. It is simple to connect to a printer and to send a job, and I enjoy being able to track the print remotely for it's progress.
