These are the 3D videos designed for services companies that have tangible work results. Your ideal client is someone who wants to do something that is impossible without expensive equipment or learning how to use it, but it’s impractical for him to buy it for one day.
The 3D animation about services reveals your ability to work out the client’s task: work process organization, used equipment, and skills of your company specialists. The target audience might be as an individual as a company that needs contractors.
The video is useful for building and renovation companies, at least. It shows your skill level and aligns the client’s expectations with your abilities.
