The program has many different components to it such as 3D models which are used in my industry. I find this application very beneficial because you can use your computer or even mobile device to run simulations with multiple parameters all at once without using too much paper. Sometimes there may be lag time when creating new designs especially if they have been sitting around waiting to get designed but i think most of those problems could easily resolve themselves via some training by one's own IT department. We do design work both domestically (US) & internationally (Canada). This software allows us to see our drawings come together quickly so we dont waste alot of expensive materials/time having mistakes brought up later after construction begins.
