General Purpose

HULLFORMREF = <hull reference object>

• Defines the name of the hull reference object for the current ship.

• Normally this parameter should not be given. The name should be fetched from the environment variable SB_HREF instead.

STRUCTUREREF = <structure reference object>

• Defines the name of the structure reference object of the current ship.

• Normally this parameter should not be given. The name should be fetched from the environment variable SB_SREF instead.

ENDCUT TABLE = <end cut table name>

• The name of an end cut table. However, normally this name should be fetched from the environment variable SB_ECUT.

FR_TERM_OUT

• By default the system always tries to translate any X-coordinate into a frame term (FR).

• This keyword controls whether the X-coordinate should be translated or not.

• The keyword can be assigned the following values:

  -1	no FR-terms are used.
  0	FR-terms with a possible offset are used.

• The system default is FR_TERM_OUT = 0.

LP_TERM_OUT

• If longitudinal positions are defined, Y- and Z-coordinates can occur as LP-terms in system generated output.

• The keyword can be assigned the following values:

  -1	no LP-terms are used
  0	LP-terms with a possible offset are used.
  1	LP-terms are used only if the offset is zero.
  2	as for 1 but also "half" LP-terms are used.

• The system default is LP_TERM_OUT = -1.

BKT_OLDPROF

• Relevant only when NEW_BKT is given.

• Sets the system in such a mode that the lengths of profiles are calculated in approximately the same way in the extended bracket as they used to be in the old in-built bracket handling.

BKT_NODEF

• Relevant only when NEW_BKT is given.

• It then has the effect that no notches are set in brackets, covered by the extended bracket handling, unless explicitly set by the user.

KNUCKLED_STIFFENERS [ = <activity>]

• Activates the handling of knuckled stiffeners.

• The parameter can be set as a stand-alone keyword, which will activate the knuckle handling of stiffeners.

• <activity> can be set to KNUCKLED or TWISTED

• If set to KNUCKLED, the knuckled stiffener handling will be active.

• If set to TWISTED, stiffeners will be smoothly twisted instead of knuckled.

MAX_KNUCKLED_ANGLE=<angle>

• This parameter controls the maximum angle between two panels that is allowed for knuckled bevels.

• <angle> is the maximum angle between two panels. If not given, the default 30 degrees will be used.

NEW_BKT

• Activates the extended bracket handling. Should normally be set (see Generation of Brackets).

SCH_EDIT_NEW

• When a panel is active and the scheme is opened in the schema editor, the normal behavior when a new panel is indicated is that the system will ask if the current panel should be applied and deactivated. By setting parameter SBH_EDIT_NEW to any value, the system will apply the current panel, if it has been modified, and then deactivate it without any questions and automatically activate the new indicated panel and make the new schema available in the editor.

SBH_OPEN_DLG

• This has effect when the Input Schema dialog should be open.

• The variable can have one of two values:

  KEYIN (default)

  • This will open a pre-dialog where the user has a chance to key in a search string, for the file/schema name, before the files in SB_SHIPSCH are presented. The benefit here is that not all files are presented. The only ones that are presented are those that match the search string from the first dialog. This is also recommended when there are a large number of files in the catalogue due to performance issues in Windows catalogues with a large number of files.

    STD

  • This will open the catalogue SB_SHIPSCH directly and present all available files in the catalogue. If there is a great number of files this will have affect on the performance.

SURFACES = <surf_no>, <surf_no>, ...

• Gives the possibility to handle multiple surfaces. <surf_no> is the reference number of the surfaces noted in the Hull References Object. Several surface numbers may be given. By default, surface number 1 and -1 is treated, meaning the original hull form and the deck form.

SURFACE_REFERENCE = <value>

• Controls the resolution of surface references in the boundary statement.

• The keyword may have the following values:

  EXISTING	means that whenever a hull curve is in the same plane as the panel referring the surface it will be used rather than intersecting the surface.
  CUT	means that the surface will always be intersected regardless of the existence of any hull curves.

• Hull curves are the curves noted in the frame, waterline and buttock coordinate tables.

SWEDGING = <swobj>

• <swobj> is the name of an object on the structure data bank containing data to define drawing of swedged bulkheads.

STI_TAG_EXCLUDE = <tag_ctrl>

• Controls the setting of "tags" in stiffeners.

• Possible values of <tag_ctrl> are:

  NONE	(default) All stiffeners will get tags
  FICT	Fictitious stiffeners will not get tags
  TEMP	Temporary stiffeners will not get tags
  FIC_TEMP	Fictitious and temporary stiffeners will not get tags
  ALL	No stiffeners will get tags

TRACEON

• If given, test prints will be produced on the log created by the program. This parameter is only intended to be used for system maintenance.

WHT

• Do not set.
