Before opening the Maxsurf model in Workshop a number of checks need to be made. This is basically the same as for Hydromax and consists of checking: 

·   Frame of Reference and Zero Point

·   Check trimming

·   Check surface Use

·   Check Surface Thickness

·   Check Outside Arrows

Before starting in Workshop check that the Maxsurf model has the correct frame of reference and zero point defined. Do not change the frame of reference after you have started defining parts in Workshop.

Ensure that all surface intersections are correct and that the model is trimmed completely.

In order to be able to form frames correctly you should have closed transverse sections (or sections with at most one opening).

In order to be able to form decks correctly, the model’s waterlines should be made up from closed polylines.

Maxsurf surfaces are divided into two types:

·   Hull shell

·   Internal structure

Workshop treats these differently. For example, an internal surface cannot be used to define a frame boundary. The following table summarises the different functions in Workshop and how the surface use property of the Maxsurf surface is treated.

The thickness assigned to the Maxsurf surfaces, is used in Workshop to form frames and stringer paths. For more information, see:

Check Outside Arrows on page 9

Deduct Skin Thickness on page 19

Plate Thickness on page 65

In order for Workshop to know which side of each surface is outside and which side is inside, you need to set the outside arrows direction in Maxsurf.

The direction of the outside arrows is used in Workshop to determine the direction of stringers (cutouts through frames) and throw direction of skin thickness (plate development, frame perimeter deduction).

You can check the direction of the outside arrows by turning on the outside arrows in the display menu or using the toolbar item:

You can change the direction of the outside arrows by clicking on the circle at the end of the arrow.

For more information on outside arrows please refer to the Maxsurf manual.
