Command Syntax:
2.3.46 JOINTNUMBERS
Function: Numbering joints in Spool Drawings on an isometric.
Description: By default SPOOLER automatically generates numbers for every joint in a Spool Drawing. These numbers can be output on an isometric by switching JOINTNumbers ON.
Note: This function has no effect when plotting isometrics from the DESIGN database.
The joints are sequentially numbered from one end of the Spool Drawing, with each number being given a prefix indicating the type of joint. The default prefixes are:
• F Flange
• S Screwed
• C Compression
Note: The ‘F, S & C’ codes are ATexts, and can be changed.
The numbers are displayed in a diamond, with an arrow pointing to the joint. If the total number of characters (prefix + number) is greater than 3, the number is displayed in angled brackets; e.g.
<FL124>.
Examples:
JOINTN ON

2.3.47 KEYS
Function: Allows components with specified SKEYS to be treated like instruments.
Description: Component types that can be tagged, that is types that can have their names plotted automatically on the isometric drawing, can be treated like instruments. This means that:
• If INSTRUMENT SPREF is set, the SPREF will be used as the itemcode.
• If INSTRUMENT NAME is set, the itemcode column will be left blank and the name will be appended to the description.
• If INSTRUMENT NAME WITH BALLOONS is set, the name will be output in a balloon on the isometric.
The types that can be tagged are:
INST VALV FILTER PCOM
TRAP VENT TWA VFWA
To treat a component type as an instrument, give each specific component type a key number, and then relate the key number to the symbol key (SKEY) by the KEYS command.
See the TAG command for more information about tagging.
Examples:
KEYS 1 ’VVFL’
Any valve with the symbol key VVFL, and which has a name, will have its name appended to its description and the itemcode column left blank. If a valve with the symbol key VVFL is not named, its SPREF will be output as its itemcode in the normal way.
KEYS 1
Remove the component from the key number list by quoting its number only.

where keynumber is the key number (which must be in the range 1 to 20) and skey is the symbol key (SKEY attribute).

2.3.48 LEGLENGTH
2.3.49 LINETHICKNESS
Function: Allows you to specify the plotted leg length of elbows, tees and crosses.
Description: By default, the plotted leg length of Elbows, Tees and Crosses is 9mm. If necessary you can change this value. The minimum leg length allowed is 6mm. If you specify a smaller value than this, ISODRAFT will give the message
Leglength set to minimum value of 6mm Examples: LEGLength 12
Command Syntax:
>--- LEGLength --- <uval> --->
Querying: Q LEGLENGTH
Q OPTIONS
Function: Allows you to control (optionally) the thickness of line used to represent piping.
Description: This command allows you to specify a line thickness (from 1 to 10) to represent piping on the isometric. A default value (3) is used if you do not specify a thickness.
Examples:
LINETHICKNESS 8
Specifies a line thickness of 8 to be used to represent piping.

>--- LINEthickness --- <uval> --->

2.3.50 LOOSEFLANGEALLOWANCE
2.3.51 MARGIN
Function: Allows you to specify an additional length of tube on cut tube to compensate for field-fitted welds and loose flanges, where the ALLO attribute has not been set.
Description: If a cut pipe list has been specified using the CUTPIPELIST command, ISODRAFT automatically includes a site fitting allowance in each calculated cut pipe length which terminates in:
• A flange with its LOOSE attribute set to TRUE (i.e. a loose flange)
• An element of generic type WELD which has the symbol key WF (i.e. a field-fit weld)
The allowance is taken from the value of the ALLO attribute for the weld or flange, if set. If the value of ALLO is not set (or zero), the allowance defaults to 150mm. The default allowance can be altered using the LOOSEFLANGEALLOWANCE command.
The fabricator and/or erector can be informed of the in-built allowance by means of a message in the title block area.
Note: The dimension shown on the isometric drawing is the actual designed dimension.
Examples:
LOOSE 4 INCH
Adds 4 inches to tube length for each field-fitted weld or loose flange with no ALLO value set.
LOOSE 0
No additional tube length added for field-fitted welds or loose flange.
Command Syntax: >--- LOOSeflangeallowance --- <uval> --->
Querying: Q LOOSeflangeallowance Q OPTions
Function: Specifies the width of the margin on each side of the drawing.
Description: By default, a 5mm wide blank margin is provided on each side of the drawing area. The MARGIN command allows you to specify the widths of the left, right, top and bottom margins independently.
