Fastening provides an Excel table named Fst_Standard in CATIA resource environment. You can customize it to specify the default fastener types set-up
values for your design.
The standard file enables the specification of the list
of reference fastener types and fastener types display, fastener design naming and check
rules, and fastener types attributes for the flat report.
The standard file is loaded
at the beginning of the session. To modify it, you need to reload your session.
The Fst_Standard file is located according to the reffiles\FstStandards path from CATIA runtime view root directory (win_b64 for Windows, aix_a for IBM UNIX, irix_a for SGI
UNIX, solaris_a for SUN UNIX, hpux_a for HP UNIX).
Two filename extensions are implemented
for this file:
.xls for Windows Operating System run time usage.
.txt for UNIX Operating System run time usage. It is the master file and must be generated from
the customized Fst_Standard.xls file on Windows using the Save as Text
Excel command. It is used for optimized run time usage.
Customization of the Fst_Standard.xls Standard File
The Fst_Standard.xls standard file can be fully customized by the company data
administrator, according to the company or industry-specific standards
requirements.
This file contains two columns:
The first column identifies the parameter name.
The second column specifies the list of possible values of the identified parameter:
value1, <value2>, value3 (brackets <>, specify the default value: value2 is
the default value of the previous list).
The rows are divided into sections:
Section A: Set Up the Company Standard Reference Fastener Type
Parameters
This first section deals with:
Fastener Types Name List and Display Symbols. A reference fastener type is characterized
by:
A mandatory Fastener Feature Type (FTYP). The possible values of
this parameter are the available PLM Fastener Modeler feature types (Fst_Spot, Fst_SpotAssy and Fst_Bead)
A mandatory Fastener Process Type (PTYP) that is made of two parameters:
A mandatory primary Process Type (PTYP1) that is a customized "Character String".
It can be defined by a graphic symbol (Weld for example) and a display color (one
color for each graphic symbol)
An optional secondary Process Type (PTYP2) that enables to precise the Process
type (for example, 21 ISO Code for Weld).
Fastener Type Attributes and their Display Properties. Attributes
can be classified according to three categories set by default to
"Engineering", "Manufacturing" and "Custom".
Important:
Categories cannot be renamed.
Attributes names must be different.
You can specify values for each attribute. Let us take an example with the "Robustness"
attribute:
You can customize the display of the symbol mark: The "Safety" value of the "Robustness" attribute deserves a specific attention, as the
"FTYP_CLASSATTR_HIGHLIGHTVALUE_Robustness" parameter has been added to the standard
table. The "Safety" value needs to be highlighted through a special 3D fastener symbol
mark, therefore the parameter has the special "Safety_1" value that means that the
fastener display mark "1" will be assigned.
Section B: Set Up the Company Standard Fastener Display and FTA
Formatting
This section is subdivided into two subsections:
Fastener Display. The administrator can set the graphic display
symbols to be assigned to each thickness count.
By default, the following
graphic symbols are assigned to the thickness count:
Code 111 is assigned to 1T stacking:
Code 151 is assigned to 2T stacking:
Code 113 is assigned to 3T stacking:
Code 114 is assigned to 4T stacking:
Fastener Annotation Format Properties. The administrator can set the fastener
annotation information code or parameter to be displayed for each FTA weld annotation:
F1, F2, F3, F4, F5.
The symbol you can create yourself to assign to the Process Type must be named in the 500 series,
that is from 501 to 599. For more information, see Defining Your Own Fastener Symbols and
Fastener Symbols.
Important:
The Process Type option must be selected to display customized symbols in the 3D area. For more information, see Fastener Technological Parameters.
Section C: Set Up the Company Standard Fastening Rules Names
Fst_RULES_STK_OrderCheck is applicable for all fastener types.
However, you can override the parameter value for specific fastener types by
redefining it in the reference type file.
The rule engines searches the parameter in fastener reference type file first (to see if
overriding exists). If it is not found there, it will take the parameter value from
the fastener standard file.
If the parameter is set to TRUE, the order of parts found in the following
two lists is verified:
Parts found in fastener intersections
Parts in fastener connections
If the parts found in the above two lists are exactly
in the same order, the rule will be OK.
If the parts are in exact reverse order, then the
result of the rule will be calculated depending on the value set for the Fst_RULES_STK_AllowReverseOrder parameter. For any other order, the rule will be
KO.
By default, this parameter is set to FALSE.
Fst_RULES_STK_AllowReverseOrder is taken into account only when
Fst_RULES_STK_OrderCheck is set to TRUE.
You can override the parameter value for specific fastener types by redefining it in
the fastener reference type file.
By default, this parameter is set to FALSE.
The administrator can customize the list of check
rules and the number of digits for the fixed-length naming rule.
List of applicable design check rules:
Section D: Set Up the Company Standard Fastener Attributes for
Reports
The administrator can customize the formatting specification of unitary
reports generated into a text file through fasteners attributes to be
displayed in appropriate columns.
