Manufacturing Curved Plates Drawings

The program generates different kinds of drawings and sketches.

Names of receipt sketches are automatically generated. See also Hull Detailed Design / Manufacturing / Production Program Interface / Automatic Naming of Production Sketches.

The drawings are automatically generated and will be stored in the PADD database pointed out by SBH_PINJIG_DWG and SBH_PINJIG_DWG_PADD. The logical name SBH_PINJIG_DWG should point to it self and for the SBH_PINJIG_DWG_PADD pointing out where these drawings are stored in PADD. See the drafting documentation for setting up the department and registry file for the SBH_PINJIG_DWG _PADD reference.

If the logical name SBH_PINJIG_DWG_PADD is not assigned the software will try to store the drawings in PADD where the standard drawings are stored (SB_PDB_PADD).

The first drawing supposes that a drawing form TB_JIGPILLAR should exist in the standard data bank, SBD_STD or SBD_FORM.

There is a standard method to tailor automatic drawings by so called "$-values", which are set in drawing forms. Some of these are replaced by texts, extracted from the information inserted into the drawing, others may be used to locate pictures. This technique is used also in the forms for jig sketches.

The list below shows the available $-texts and the corresponding variable to replace the $-text.

The $-texts 1998 and 1999 must be given while the others are optional.

The resulting sketch is a projection of the panel on the assembly plane and it is located in the first quadrant of the local coordinate system where the x-axis is the sight line and the y-axis the direction line. Furthermore, the drawing contains:

• The name of the JIG object.

• The boundary seams with their numbers.

• Inner seams with their numbers.

• Orientation information about those of the edges, not located close to the coordinate axes.

Optional values are:

The x-axis is identified by Sightline (X) and the y-axis by Directionline (Y).

• The corners of the panel are identified by their numbers surrounded by a circle.

• The jig row designations A, B, … are drawn below the x-axis.

• The jig pillar numbers are drawn to the left of the y-axis.

• Every calculated jig pillar will be marked on the drawing by a cross, X.

• The height of the jig pillars is by default drawn to the right of the jig pillar cross. The position may be placed below the cross in case the IP FIGBELOW has been given (except for the first jig pillar in each jig row where the height is drawn above the cross).

For an example of a resulting drawing, see Normal Bending Templates.

The second drawing will be named JPIL_<job_number>_2(2). It contains side views of all the jig rows in a plane perpendicular to the assembly plane and parallel to the y-axis.

Each side view contains:

• The name of the jig object and the designation of the jig row preceded by the name jig row.

• The assembly plane and a cross mark for the sight line (x-axis).

• The jig curve, that is the intersection curve between the panel and the plane of the jig row.

• The jig pillars marked by arrows. For every fourth jig pillar its designation and height will be drawn.

• The inner seams that intersect the jig curve.

If the panel has been built up by input (that is, via PANEL_NAME and SEAM statements), an additional sketch will be included in the second drawing. This sketch is in fact the result from the initial stage in the run. The sketch contains:

• The name of the jig object.

• The boundary seams with their numbers.

• Inner seams with their numbers.

• Heights over the assembly plane for the corners of the panel, identified by the word Height.

• Marking of the lowest point of the panel, identified by a certain symbol.

• The intersection line between the assembly plane and a frame plane (identified by Fra-Plane) and the intersection line between the assembly plane and a waterline plane (identified by WL-Plane).

The heights of the corners above the assembly plane are valid when the lowest point touches the assembly plane.

One of the intersection lines (or a line parallel to one of those on the opposite side of the panel) is then chosen as the direction line.
