Plate Corners

One GSD is placed at the predefined distance (CORNER_DIST) from the corner of the plate along each of the boundaries/seams that meet in the corner. The GSD:s are placed in the nominal position, disregarding excess, gaps, The orientation of the GSD is perpendicular to the boundary curve. In case of a triangular GSD the triangle is facing away from the corner. The figure below shows a plate edge to be fillet welded against a base plate.

Figure 2:4. GSD:s at Plate Edge.

The position of a GSD is affected differently by notches and cutouts in the corner depending on the default USE_WELD_TRACE.

GSD:s will only be placed on boundaries defined by reference to the surrounding structure, a hull curve, a stored plane or any edge where WELD is defined, that means, free edges will not get GSD:s. This can be overridden by the default GSD_AT_FREE. The figure below shows a case where GSD:s have been set in all corners.

Figure 2:5. GSD:s in all Corners.

GSD:s will not be placed at plate corners where the boundaries intersect at 180 degrees.

At the intersection of the boundary or a seam with an internal plate seam, one GSD will be placed on the seam only (that means, at T-junctions). This can be overridden by the default GSD_AT_T. The figure below shows the effect of this parameter.

Figure 2:6. The effect of GSD_AT_T.

GSD:s will not be placed on boundaries with flanges or where the geometry of the plate edge does not allow it.

GSD:s will not be placed on boundaries defined by reference to a profile on another panel (for example, profile cross section).

GSD:s will not be set on inner seams for assembly parts (for the panel line).
