The ability to create, edit & publish models for clients in seconds instead of hours or days! I've been using this software since 2011 when we were first introduced by our design consultants at EY who used it every day with their own engineering teams while working together as part 1st engineers - they're still very impressed that after 7 years there's no major issues left over from those early trials so you can be assured your new product will also run without hassle once released into production use (which does happen sometimes!). It was just an added benefit having them around because if anything went wrong whilst being trained up then not least would have had someone else nearby able/willing enough know what needed doing!! As mentioned above its great but best thing about ACube compared some older applications outthere like Autodesk Revit etc which are difficult even though free versions available nowdays? Its speed / easeofuse factor especially considering how easy their training.
