4. In the "1st nominal diameter" and "2nd nominal diameter" fields, specify the component
connector for which the value is valid.
If
the pipe part has only one nominal diameter: Select "Ignore" for "2nd nominal diameter".
5. Click the "OK" button.
3.5.2.12 "Def(...)" function
You can only input the "Def(...)" calculation formula manually.
Procedure
Pass a value as a parameter that serves as the starting value and can be replaced by another
value at a later stage in the engineering data.
Example:
Def(2500)
Result
If the base object is changed in the engineering data, the attribute value that was input at the
pipe part is always retained.
In contrast, if you input the starting value directly into the attribute in the base data, when the
base object is changed, the attribute value input at the object is replaced by the value defined
at the new base object.
3.5.3 Assigning bolt sets to a pipe part
If you assign a bolt set to a pipe part or pipe spec element and the "Pipe spec dependent"
options are not enabled at the bolt set, the assigned bolt set is generated during bolt calculation.
Otherwise, a bolt set that was defined in the pipe spec is generated.
See also chapter Fundamentals of bolt sets (Page 63).
Requirement
You have already prepared bolt sets in the base data. See also chapter Preparing bolt sets
(Page 63).
Procedure
1. Open the properties of a bolted pipe part or pipe spec element.
2. Select the "Connection <1-n>" tab , which contains the control groups "Information - First
bolt circle" and "Information - Second bolt circle".
3. Select the bolted type in the control group "Information - First bolt circle".
