The ability of this product to create and edit models with ease, it's user friendly and simple. I love that I can easily send my files to someone else who does not have access by sharing my password because you can share your folder so they don't need access to see everything but just what you want them to see. Sometimes when using shark cadd, the program hangs up for no reason and makes me lose all progress making it very hard to continue working without losing work. There are some things about shark cad that I like such as being able to import different file formats. It also has many features within its system which made it great since we were trying to learn how to use this particular feature before starting our project.
