Main Characteristics of Implementation

A conclusion of the description above is that this feature consists of two parts:

1. Translation forth and back between the customer specific endcut strings and the corresponding internal AVEVA Marine representation.

2. Modification/update of the given endcut strings with measurements, calculated from the connection angles.

The second of these issues is addressed first.

Suppose the simple case illustrated by the figure below,

Figure 11:1. Endcuts with calculated connection angles.

Traditionally the endcut would in this case have been specified as CUT=1120 in both cases. The result after generation will in the two cases be equal to CUT=1120, 60 and CUT=1120, 120, respectively.

The corresponding endcut string should be Cb173R50 and Ca173R50, respectively (here 173 is the result of the connection angle and the profile height). But beforehand the designer may not know the connection angle and thus not whether it is <90, >90 or should happen to be exactly 90 degrees. So the question is: How should he present his request for endcut to the AVEVA Marine modelling function?

The following approach has been chosen as a general feature. The endcut should be specified (in this case) as:

C$##aR50

Here:

Thus, when the designer gives an endcut string containing $ and ## he expects the system to exchange these characters by appropriate values, evaluated from the result of the modelling. These characters are allowed only immediately following the leading character specifying the endcut type.

The mapping from endcut strings to AVEVA Marine endcuts are performed by the aid of a translation file that is described in the next section.
