Yes, I understand I can increase the width of the tank, but this is not useful if i don`t want a tank with great width. There is also the same problem with the vertical tank. I also get that it`s possible to do this manually by using text object numbers, but this is a lot of work, and does not work if you suddenly need to change the scale interval. It was more of suggestion on what can improve with your software.
Thanks for your reply.
