3.5.4.4 Restricting the nominal diameter range of a pipe part
Requirement
You have opened the "Display for nominal diameter range" tab.
Procedure
1.
To exclude nominal diameters from or add them to the nominal diameter range which is 
generally available for the pipe part, click once with the left mouse button in a cell:
– Option was activated: The option is deactivated. The nominal diameter is no longer in 
the nominal diameter range.
– Option was deactivated: The option is activated. The nominal diameter is in the nominal 
diameter range.
You can only edit the white cells.
2. Save your entries.
Result
● You have defined the nominal diameter range in which the pipe part is available.
● The nominal diameter range is saved at the pipe part as an XML string in the "Y00A04288 
Nominal diameter range" attribute.

3.5.4.5 Integration into existing databases
If you are already working with an existing database and the "GD.NDRange" attribute and 
associated XML strings have not yet been generated for its pipe part base objects, you should 
convert the base objects of the pipe parts once only. 
If you do not convert the base objects in the base project, COMOS cannot create the attribute 
in the engineering data. The permitted nominal diameter range must always be recalculated 
every time it is called. This can lead to a decrease in performance.
Note
The time taken to complete the conversion depends upon the number of pipe parts. Run the 
conversion overnight if necessary.
Script for conversion
To run the conversion, implement the following script at the structure object of the pipe part 
catalog or execute it via the object debugger:
"Set Checklib = CreateObject ("ComosPPCObjectCheck.Lib")
