I really like working from my computer as opposed to having paper layouts or drawings sent back home by email which can be lost etc.. Also being able use this application anywhere without needing special software (like AutoCAD). There are not many things that you dislike about SafeConcretes products but we have had some issues over time such an error messages where it freezes up when trying save certain designs even though nothing has changed? We also recently upgraded our computers so there were compatibility problems at first till they figured out how best handle those changes! Our main focus was creating accurate plans/drawings quickly using safe concreting tools rather than drafting traditional methods.
