I am trying to model a sea floor area of around 1 km X 1 km area. As the floor would be uneven and wavy, what will be best way to create such a surface? I tried using the free form feature, but that is a time consuming feature where I would need to pull and stretch each single dots/points. Is there something I can do automatically or pattern? The same goes for a sea surface on top with waves etc. Thanks in advance.
