The Seam element models a shell seam. It has a curve definition and a limit box:

The Box element is optional. If the box is omitted the box defined in the current Defaults element will be used. If there is no Defaults element, the curve will unrestricted along all coordinate axes.
The Seam element has three attributes:
|
ObjId |
The name of the seam, required. The attribute value must apply to the general AVEVA Marine rules for naming objects. |
|
Refl |
When set to "true" this flag indicates the resulting seam will be a reflected (in CL) version of the given seam specification. This is an optional attribute, the default value is "false". |
|
Symmetry |
The symmetry of the seam, possible values are "Auto", "Symmetric", "SB" (valid SB only), "PS" (valid PS only) and "CL" (over/in CL). The value "Auto" means that the symmetry will be selected automatically: a seam which is completely on the PS side will be valid for both SB and PS, a seam on the SB side will be valid only SB and a seam over CL or in CL will be "over/in CL". The attribute is optional, the default value is "Auto" |
|
BlockLimit |
Indicated is the seam is a block limit, optional. Possible values are "true" or "false", the default value is "false". |
As shown in the picture above, the curve can be defined in a number of ways all recognized from interactive curved hull:
-
by intersection between a surface and a plane.
-
by intersection between a surface and a general cylinder
-
parallel another curve
-
as a combination of two other curves
-
from an existing hull curve or from a curve in an external surface system
