Respec
Changing the specification of existing pipework can be done by first selecting all relevant inline parts and then change the PSPEC attribute in the Shape Data window. The new spec will be applied to all the selected inline parts. After this, the spec selection process will automatically be triggered and changes to Sprefs can be followed up by viewing the Message Log.
Note:
In order to get a good overview of what happens during the respec operation, it is recommended to only respec a reasonable number of parts in the same operation. This makes it easier to follow up and check any changes.
Note:
To select, in the current drawing, all inline parts in a branch or a pipeline, it is possible to right click on the branch or pipeline in the explorer and use the Select in Drawing command.
In the case where a diagram has been created without using any specification, and you subsequently want to apply a spec, the below procedure can be followed:
1.
Go to the Diagrams Options dialogue and change the Use specification default setting under General options > Pipe Dimensioning > Spec search to True.
2.
Also make sure that any desired propagation settings such as Refit – Propagate Autofit, Refit – Propagate at Segment and Refit – Propagate at Branch are set to True.
3.
Close the Diagrams Options dialogue.
4.
Click on the first tube/fitting in the branch you want to apply spec search to and select pipeline properties.
5.
In the Pipeline Properties dialogue, go to the Specification tab and select a Pipe spec.
6.
Click OK to close the dialogue.
7.
Select the first tube or fitting in the branch, right click and choose Refit. The specification search will now be carried out and propagated according to the propagation settings.
