1 New Handling of Seams and Plates

• DescriptionPreviously, the seams had to be generated first and then the plates. If the seamarrangement had to be changed the result could be that the plates had to be deleted andthen regenerated. This is now changed to the dependency between the seams and platesbeing handled automatically by the system.

When generating seams the plates will be automatically updated. This update includes theuser-defined point given in the plate definition. If a plate is defined and later on divided by aseam it will become two plates inheriting the attributes (thickness, quality, …) from theoriginal plate.

When deleting a seam the plates bounded by that seam will be merged with thecorresponding plate on the opposite side of the seam.

When moving seams the system will make sure that the number of plates is correct and thattheir definition points are updated.

For example, a simple square panel originally with no seams and one plate defined.

Now add a seam on Z=500 cutting the existing plate in two. The plate statement has nowbecome two, with points added automatically by the system:

Adding another more complex seam along a curve will split the two plates into five plates:

The scheme now looks like:

While generating, the order between the plates and seams in the scheme does not matter,but after storing the panel the seams are placed before the plates in the scheme due to theinternal topological sorting.

2 Improvements in RSO - Create

• DescriptionPreviously, when creating an RSO, a number of panels had to be activated. The activatedpanels were the ones to form the RSO. In that process both instances of a symmetricalpanel were used, if the panel was not located parallel to CL. However there was no way topick only one instance from a symmetrical panel.

Now panel instances are picked and highlighted rather than panels. In the dialog the string"(reflected)" after the panel name indicates a reflected panel instance. The panel location isupdated only if the non-reflected panel instance is included in the RSO.

• BenefitsImproved control of the created RSO when using symmetrical panels.

• Compatibility ConstraintsNone.

3 Improvements in RSO - Delete

• DescriptionPreviously when deleting an RSO, the location of the panels referred from the RSO was notchanged even if it was depending on the RSO. This was then up to the user to change if theRSO was permanently deleted and not created again.

Now the panels are updated provided that they are referred from the RSO and that theirlocation is defined by the RSO. The new location will be derived from the panel plane andwill be either a position along one of the principal axes, or three points.

• BenefitsPanels with location by an RSO are automatically updated when deleting the RSO.

• Compatibility ConstraintsNone.

4 New Function RSO - ReCreate

• DescriptionA new function, ReCreate, has been added to the RSO sub-menu. It is intended to be usedwhen the panels forming an RSO has changed in shape. By picking the RSO the samedialog will appear as in the Create function listing the referred panels. The geometry of theRSO will then be adapted to the panel boundaries.

It is necessary that the panels are noted in the RSO as they would be for example if theRSO was once created from the panels and the panel location was then updated to refer theRSO. Otherwise the RSO cannot be recreated.

Previously this had to be done via the Create function manually picking all the panels toform the RSO.

• BenefitsEasier to recreate an existing RSO from the referred panels.

• Compatibility ConstraintsNone.

5 Referring RSO’s in Panel Generation

• DescriptionThe modelling of planar panels is to a large extent built on references to the surroundingstructure. Many of these references are to the plate surface of panels intersecting the planeof the modelled panel or to stiffeners on such panels.

However, if substantial modifications are made to the referred panels, such as movingboundaries between panels, the references may become invalid. One way to overcome thisand make the reference more stable is to refer an RSO containing these panels rather thanthe panels themselves. The RSO is supposed to cover for example a whole deck and will beunaffected by the panel subdivision.

This is similar to the use of SF and SL terms inside a panel to make the stiffener referencesstable. So an RSO can be for panels something like what a longitudinal position can be forstiffeners.

If such a reference is made to a panel that is positioned by an RSO (…,LOC='<RSOname>',…), the reference can be made via the RSO instead. If a stiffener is referred viaRSO it has to be via SF or SL terms.

The RSO reference above can be used when defining a boundary, when setting cutouts forstiffeners, when connecting stiffeners or brackets to intersecting stiffeners or to a platesurface. Also the RSO can be used when defining topological points and fillet curves in thesituations mentioned above. Finally, also ‘pillar end against plate surface’, ‘flange endagainst stiffener’ and ‘seam for panel’ can use RSO reference.

• BenefitsMore stable references when using RSOs instead of panels.

• Compatibility ConstraintsNone.

6 Block Division news

• DescriptionFrom Tribon M3 Reference Surfaces (RSOs) can be used both to cut the panels in the blockto split and as block boundaries. Also a stiffener offset can be defined.

When selecting the cutting objects RSOs can now also be selected. Unlike the planes andRSO is limited in space. In order for an RSO to cut a panel it must intersect the panelboundary twice, cutting the panel in two. The RSO will be used a s part of the definition ofthe boundaries of the two new panels. By using RSOs the panels can be cut by complexshapes.

Also the blocks can use RSOs to defined its extension. Apart from the limiting box an RSOcan be assigned to eahc of the six limits (Aft, Forward, Portside, Starboard, Top and Bottom)as a refinement. When comparing a panel against the block in the Block Division process,the box is used initially but then also a check is done against the optional RSO.

The user interface now also contains a dialog collecting what was previously a numer ofquestions.

In this dialog also an option is added to define stiffener offsets (shift) around the cuttingplane. A number of offset values can be chosen from a drop-down list. The values in the listoriginate from the connection code setup (SBH_CONCODES). All matching pairs of gap/overlap from connection codes of type 4 ( profile end/ profile end) will be included. Pickinge.g. 200 will make the sitffeners be cut 200 mm from the plate edge in the direction of thenormal vector of the plane (normally in the direction of a principal axis). Picking -200 will cutthe stiffeners 200 mm from the plate edge in the opposite direction.

• BenefitsRSOs can be used in Block Division. A stiffener offset can be defined.

• Compatibility ConstraintsNone.
