Primary Goal:
To export specification-driven piping and piping components that were modeled in Creo 8.0.3.0 as a Piping Configuration File (PCF) that can be opened and modified in a pipe-stress analysis software (AutoPIPE, v 23.00.00.230).
Methodology:
Piping is modeled as Spec-Driven per Creo Guidance and YouTube Tutorials, and pipe components are similarly modeled per Creo Guidance and YouTube Tutorials. To export Creo model as PCF, Creo guidance is again followed.
This process has been tested and proven to be able to export complete pipeline PCFs that can be read/interpreted by AutoPIPE.
Problem:
The PCF export of some (but not all) pipe tees is encountering errors when following this methodology. During the export process, the coordinates for the center location of the branching member of the tee are shifted to instead read as the coordinates of one of the end points of the tee, as shown in the diagram below:
One might assume that the reason for this issue is sourced in some error or mistake that was made during the modeling of the tee in Creo. However, what has been seen (and what is the cause for me making this post), is that the process of performing a PCF export of multiple copies of the same exact tee results in different coordinate placements between those same exact tees. This observation is demonstrated below:
The pipeline in Creo uses the same tees within the assembly. When the pipeline is selected for export as a PCF, it results in the following:
Here, despite all tees being copies of the same exact part, one is exported from Creo into the PCF with inaccurate coordinates for its center point. This would lead one to believe that the issue stems from the way Creo generates PCFs, and not with the way the tee is modeled. Similar issues have been seen where the branch point has no offset distance from the mainline pipe segment of the tee, and perhaps that additional error is similarly tied to the way Creo generates the PCF.
If any guidance can be given for how to address this issue it would be greatly appreciated.
