Maxsurf can also quickly calculate the Surface areas for you. This information may be useful when you are trying to estimate a steel weight for a surface (3D surface area) or the windage area of the model above the waterline (2D projected lateral area). All this data is available in one dialog.

Ø  Read the Calculate Areas section of the Maxsurf manual.

Ø  Calculate the 3D true surface area for your MyFirstDesign_TrimmingComplete.msd

Ø  Do this with trimming on / off to see the difference

In case you wish to calculate the total 3D true surface area for all surfaces except for, for example the Transom, you can hide that particular surface.

Ø  Hide the Transom and Calculate the Areas

You’ll see that the transom is now not included in the Surface area list.

The last short section in this training manual is on Chapter 11 Data Exchange.
