Fitting Master Catalog File
Default Path
<Creo load point>/text/piping_data/master_catalog/fitting
A Fitting Master Catalog file is created for each style and material code of pipe fittings, for example elbows reducers.
Based on the selected pipe or fitting, Spec-Driven Piping retrieves a fitting part that meets the schedule rate, end type and pipe size criteria from the Fitting Master Catalog file.
To automate the creation of fitting MCAT file, you can extract the fitting model information and automatically create the fitting CSV file .
The Fitting Master Catalog file format is described in the table below.
Field Name
Description
BOLT_NUT_CODE
Optional. Bolt nut code
MATL_CODE
Material code
MATL_DESC
Material description
SCH_RATE
Fitting rating.
SIZE
Fitting inlet nominal diameter.
NSIZE
Fitting outlet nominal diameter. Only required when it is applicable to this particular fitting.
BSIZE
Fitting branch outlet nominal diameter. Only required when it is applicable to this particular fitting.
END_TYPE
Fitting inlet end type.
NEND_TYPE
Fitting outlet end type.
FITT_MODEL_NAME
Fitting model name. It can be the name of a .prt (Part) or a .asm (Assembly) file, or an instance of a family table from the Fitting Library.
Bolt Nut Selection File
Default Path
<Creo load point>/text/piping_data/master_catalog/piping_bolt_nut_select.csv
A default bolt nut code can be assigned to a fitting in the auto-selection file. When you insert the fitting, you can change the bolt nut code by setting the BOLT_NUT_CODE fitting parameter.
The Bolt Nut Selection file contains one or more material classification codes (MCCS) and other parameter values assigned to a fitting with a particular size and rating.
 
* Use the piping_bolt_nut_select_file configuration option to set the Bolt Nut Selection file.
The format for the Bolt Nut Selection file is described in the table below.
Field Name
Description
BOLT_NUT_CODE
Code identifying the bolt and nut for this pipe size and fitting pressure rating
SIZE
Fitting size
SCH_RATE
Schedule rating of the fitting
MCCS_CODE
Material classification code of the bolt and nut
QUANTITY
Number of bolts and nuts for this particular bolt nut code
BULK_ITEM_NAME
Bulk instance name
