TYPE

is the standard type of a certain cutout.

<type_code>::= <integer>

Note: This keyword can be left out altogether so that the cutout type is treated as a statement value, assigned directly to the statement keyword.

<symmetry>

Normally cutouts on a symmetric panel are supposed to be valid both portside and starboard.

However, it is possible to indicate that a cutout should be used portside only or starboard only. This clause is relevant on a symmetric panel ("SBPS panel") only.

<symmetry>::= P | S

P means portside specific,

S means starboard specific.

May not be set in knuckled subpanels.

<ext_prof_ref>

defines the profile for which the cutout should be made. See General Layout of a Statement.

Cutouts for flanges cannot be made, however, see below.

<inters_pan>

defines a small T-profile like a panel with a flange intersecting the current panel.

Note: Only the panel name should be given.

<inters_pan>::= <name>

C

Certain cutout types have one sloping edge, the slope of which is controllable. The slope is controlled by the measure C in the cutout standards.

<slope>::= <number>

For customer defined cutouts the following specific rules are related to the control of the slope:

• The slope can be controlled in all cases except on the side where the cutout has a "lug", that means, is supposed to be welded to the profile.

• The measure assigned to C should always be the deviation from the point where the cutout would cut the base line were C not given.

• For cutouts which are open on both sides, any of the sides might get the slope.

C>0 places the slope on the non-mold line (flange) side, C<0 on the mold line side

M1          

is relevant only for cutouts defined in the external cutout definition. It may be used for all open cutouts.

M1 is the distance from the mold line to the cutout contour on the free side as indicated in the image below.

For cutouts which are open on both sides, M1>0 defines the distance on the non-mold line (flange) side of the profile, M1<0 on the mold line side.

<width>::= <number>

CLIP

Defines the clip arrangement according to built in standard.

<clip_code>::= <integer>

clip dimensions

CL1-CL3 are used to define the dimensions of the clips, if they are not to follow the rules stated in the Design Standards. CL1 corresponds to the first (leftmost) image of the three-image clip code assigned to CLIP, CL2 to the second one,

CL1-CL3 may only be used when the corresponding image of the clip code is not equal to zero.

<clip_dim>::= [[<breadth,]<length>,]<thickn>

<breadth>::=<length>::=<thickn>::=<number>

Three numbers assigned to one of the keywords will be interpreted as the breadth, the length and the thickness respectively of the clip - two numbers as the length and the thickness and one number as the thickness. In the latter two cases, the missing measures will be calculated according to the rules of the standards.

AREA

When clips are dimensioned automatically, their sizes might be controlled by the fact that the cutout should have a total connection area against the profile section.

(Relevant only for built-in Clips standard).

The area should be given in square cm's.

<area>::= <number>

CT1

This is the type of a customer defined clip.

CT1 is valid for the clip on the mold line side of the profile (or for a clip covering the whole cutout).

<clip_sel>::= <value>

CT2

Ditto for a clip on the non-mold line side of the profile.

CT3

Ditto in the event that there is a separate clip on top of the profile.

The keywords CT1, CT2 and CT3 cannot be used in combination with the keyword CLI.

SIDE

Used to control on which side of the panel the clip(s) should be located.

<direction>::= AFT|FOR|SB|PS|TOP|BOT

If not given the clip(s) are placed on the molded side of the panel.

PO1

The position number of clip number 1 (valid for the clip selected via CT1).

PO2,PO3

Ditto for the second and third clip (if any).

(If SB/PS specific position numbers are required, PP01, SP01 a.s.o. have to be given.)

NO1

The internal number of clip number 1 (valid for the clip selected via CT1).

NO2,NO3

Ditto for the second and third clip (if any).

MAT

One value is given: The thickness of the clip. Not relevant for standard clips. If omitted then the clip will get the same thickness as the plate to which it is welded, unless otherwise defined by the macro.

Two values are given: The material thickness may also be defined by two coordinates to the faces of the clip in the direction of the positive and negative w-axis, respectively. In this case the clip thickness is given by dist1 - dist2.

WELD

Defines the weld size in general for welding of the clips. Unless otherwise specified this weld will be valid for all welds of the current clip.

WCLIP

In case there is a need separately to control the welding of a seam within a clip this keyword can be used. Otherwise handled as WELD.

WPROF

In case there is a need separately to control the welding against the profile compared to other welds of the clip this keyword can be used. Otherwise handled as WELD.

WSHELL

Ditto welding against the plate that is carrying the profile (which, for longitudinals and transversals, is the shell). Otherwise treated as WELD. (Irrelevant for clip 3.)

BCLIP

Bevel type when two clips are welded together and have to be beveled beforehand.

BWEB

Bevel type against the web of the profile section.

BCWEB

Bevel type against the web of the profile section if coinciding with cutout contour. Default is BWEB.

BFLA

Bevel type against the flange of the profile section.

BCFLA

Bevel type against the flange of the profile section if coinciding with cutout contour. Default is BFLA.

BSHELL

Bevel type against the shell (or plate carrying the profile).

BCSHELL

Bevel type against the shell (or plate carrying the profile) if coinciding with panel contour. Default is BSHELL.

NABU

Switch off automatic bevel for the cutout.

NABI

Switch off automatic bevel for the clips.

GRI

Defines the grinding for the cutout.

SURFACE

The surface treatment of the clip(s) before the production phase. The value to be assigned must be selected among the surface treatment strings defined by the customer. See Surface Treatment in Hull Setup and Customization. Default is plate surface treatment.

DESTINATION

The workshop destination showing where the clip(s) are to be assembled. The value to be assigned must be selected from the destination strings defined by the customer. See Destination Definition in Hull Setup and Customization. Default is plate destination.

QUALITY

Quality of clip(s). If not given, it is assumed to be equal to that of the plate onto which they are welded. If the environment variable SBH_NO_CLIPQUAL_PLATE is set, no quality from the plate will be fetched.

EXCESS

Excess on the edge of the clip(s) abutting the shell (or plate carrying the profile).

EXCESS, EX2

Excess on the edge of the clip(s) abutting the shell (or plate carrying the profile).

If EX2 is given the second clips will get this value.

<assembly_info>

Specifies the name of the assembly in which the clip(s) will be used.

The default assembly will be selected as the lowest assembly level common to both the current panel and the panel carrying the profile provided that the environment variable SBH_CLIP_DEF_ASS is set to COMMON.

COLOUR

Color of all clips defined in the statement.

COMMENT

An arbitrary comment string.

CLH1

parameterized designation of standardised holes for clip 1.

CLH2

parameterized designation of standardised holes for clip 2.

CLH3

parameterized designation of standardised holes for clip 3.

HU

u coordinate

HW

v coordinate

HT

Inclination of hole

Some parameters may be defined by the clip macros. If not given as input the values set in the macro will be used as a default.

Example: (standard clips):

      CUT, TYP=53, CLI=012, AREA=60, L110-230;

      CUT, 3, 'AA462-7', SL2, CLI=777;

      CUT, TYP=53, L110, REF, CLI=010, CL2=340, 15;

      CUT, TYP=5, 'GIRDER';

Example: (customer defined clips):

      CUT, TYP=10, CT1=101, CT2=102, L120(1)5,            SID=FOR,MAT=8;

      CUT, TYP=10, CT1=100, CT2=103, L130(10)200, SID=AFT,

      MAT=10, QUA=A36, PO1=100-107, PO2=108-115,

      NO1=1-8, NO2=9-16;

      CUT, 10, CT1=101, CT3=102, L120(1)5,            SID=FOR,MAT=8,CLH1='D20', CLH3='D25', HU=55,60,            HV=45,65;
