Easy drag and drop functionality for creating drawings with multiple sheets and sections. The program has great customer support and is very easy to learn. I have only been using it since March but have not had any problems with it. It would be nice if there was more room on the screen. The space available makes it difficult to see all of the information at once. I highly recommend this product as it does help increase productivity when working in a team environment. There are many benefits such as being able to easily communicate with other people involved in a project or job. I am also able to create and manage different sections of my drawing without having to download a new sheet for each one.
