Using The "Cat - Siemens COMOS Operating Manual

Example
The following calculation formula is entered in the "OutD1 (OD1)" attribute at the base object
of a weld neck flange: =CatStd("%Y00T00011.Y00A00038%.A10.A10.A20.A10",
"Y00A00657", "Y00T00011.Y00A00003AA01" )
1. COMOS calculates the current nominal diameter of the flange.
2. COMOS replaces the "%Y00T00011.Y00A00038%" variable in the calculation formula with
the value of the "%Y00T00011.Y00A00038%" attribute in the engineering data at the
flange:
– Tag: "%Y00T00011.Y00A00038%"
– DisplayValue: "EN/DIN Metric"
– Value "Y00T00011.Y00A00038%": "1"
COMOS compiles the path to the geometry table:
"@30 > M23 > A10 > Y30 > A10 > 1 > A10 > A10 > A20 > A10 Seamless and welded steel
pipes according to EN 10220"
3. COMOS takes the value entered for the current nominal diameter from column "AD1" and
writes it to the "OutD1 (AD)" attribute.
Entering the calculation formula manually
If you enter the calculation formula manually, you are free to decide where a variable is used
and where a fixed name is used in parameter 1.

3.5.2.6 Using the "Cat(...)" function
Functional principle of "Cat(...)"
● In the engineering view, the dimension value is taken from the local dimensions that are
maintained at the pipe part: Properties of the component, "Local Dimensions" tab,
"Y00A00567 Nominal-diameter-dependent table"
● The value is determined based on the nominal diameter parameter.
Requirement
You have selected the "Cat(...)" function in the "Function" field of the "Define catalog access"
window.
