I really like that it shows you what is going wrong in your building process so there are no surprises when they get their first drawing back from our design team (we've been using them for some time). It's not as good if all of one or two things have changed at once - we had an issue where something was moved around which caused problems but this wasn't obvious until after production started! Also sometimes errors will show up during construction before final submission has happened; however these do seem pretty minor issues compared my bigger ones such getting approval etc I like that it is very easy to use. It has an excellent user interface which makes it simple for anyone who is new to this type of software to learn how to use it. It's also very cost effective. The only thing I dislike about it is that there could be more features added to it in order to make it more user friendly. We are using this tool to create our house plans and it has been extremely helpful so far.
