Optional Positions

AVEVA Marine offers three different options for placing of the reference point of a profile.

1. It is supposed always to be located in the plate surface, see figure below, that means, the fact that an inclination of the profile may "lift" the reference point from the plate surface is neglected. This is the default option.

2. The second option is that the reference point is located as though the edge of the web welded against the plate is rectangular, see figure below. Compared to option 1 there is only a difference when the angle between the profile web and the plate surface is larger than 90 degrees. In this case the profile section will be "lifted up" having the base of the non mould line side on the same level as the surface.

3. The third alternative is a compromise between the other two alternatives, namely that the midpoint of the web is located in the plate surface. This is the case both when the angle between the web and the surface is smaller or larger than 90 degrees.
