Plates related to plates split by seams

Plates which have soft seams splitting the plate into two or more pieces are called panels. The pieces resulting from the splitting are called plate parts. In addition to soft seams, plates can also be split by slots/splitters or holes, or a combination of these.

The panel remains a single entity in the Hull construction database, but the plate parts have their own logistical record, and can therefore have different thicknesses and material types. The thickness and material type can be changed individually for each plate part. Shrinkage compensation is applied on the complete panel.

Relations

Plates that are related to panels in cross-section consider the different thicknesses of the plate parts of the panel, and the possible tapering between the plate parts, so that the plate's contour follows the contour of the plate parts as a continuous line. See Presentation of thickness difference in cross-section.

Also the bevels on the plate parts are taken into account. If the thicknesses of the plate parts are changed later, or seams are deleted or moved,the system adjusts the plate accordingly.

A taper line can be indicated when defining a relation if the relation is a 1 vector relation, unless parallel distance is added. There can also be tapering between the panel and the related plate.

In case of a complete relation, a plate's relation to a panel plate in cross-section is a relation to the complete panel, not to any of the plate parts comprising the panel.

Parallel distance

If parallel distance is added when relating a plate to a panel in cross-section, and the panel has plate parts with different thicknesses, the distance between the plate and the panel is measured from the plate part which is nearest to the indication point.

When parallel distance is added, a taper line cannot be used as a 1 vector relation. The indicated plate part is used as the basis for the relation in this case.

Bevels on the related plate

A plate related to a panel can have more than one bevel. A bevel is determined for each part of the plate that connects to a plate part of a panel. The bevel type is determined based on the connected plate part's thickness and material type, according to the plate beveling rules.
