Reflection in Hull Element Names and Hurefl Attribute

Description

Slightly changed naming rules apply for hull elements created in the Design database by Planar and Curved Hull:

• For any non-symmetric object there will be only one element. The name of this element will be equal to the object name as given by the user (or in some cases automatically by the system).

• For a symmetric object there will be two elements. One of these will be named as the object and one will have a name composed by the object name and a _R suffix (R meaning "reflected").

• For a symmetric object with the geometry defined on PS, the PS element will have the shorter name and the SB element will have a _R suffix.

• For a symmetric object with the geometry defined on SB, the SB element will have the shorter name and the PS element will have a _R suffix. Currently only planar panels can be symmetric and have their geometry defined on SB.

The Hurefl attribute will strictly answer the question "Is the current element in its reflected position relative to where the geometry is defined?" This implies two things:

• Even a non-symmetric element may have a Hurefl value of True.

• The Hurefl value (True/False) and the element name (with or without _R suffix) will not always match.

Benefits

There will be less confusion regarding element names for non-symmetric objects, and there will for certain always be an element with the object name as given by the user. This solution is more intuitive and customised development may be simpler as well. Still functionality using the Hurefl attribute, for example, weld detection, will work properly.

Compatibility Constraints

Objects generated in AVEVA Marine 12.0 that are valid on one side but with the geometry on the other must be recreated before the new rules for element name and Hurefl fully apply. Note in particular that this applies to SB specific curved panels, which internally have their geometry reflected to PS. The objects are recreated via the Recreate functions in the Planar Hull and Curved Hull menus, respectively.
