Hello Peter, The standard procedure for figuring out a PCF / NTL file issue is to open the file in any word editing program (ie. Notepad ++ or Ultra Edit), select and delete the 2nd half of the model, save the file, and try to import the model. Repeat as necessary removing parts of the file until the model is imported without issue. Then add parts of the deleted section unitl the imported file fails to import. Finally, after narrowing down the problem section review the syntax where the problem exists with AutoPIPE's online help Command Card Reference section to under stand why. Remember to keep AutoPIPE other limitations in mind during this review to help understand why the error has occurred.. In your case, the model was trying to create a closed loop based on node point 89, the large diameter of a reducer. AutoPIPE has a limitation that does not allow a segment to start nor end at a component (i.e. bend, reducer, etc..). Otherwise the following is displayed: --------------------------- Error --------------------------- E753-18: Cannot be reducer face --------------------------- OK --------------------------- or --------------------------- Error --------------------------- E753-21: Error creating a closed loop, cannot specify existing point name on the same segment. Add a new segment to create a closed loop. --------------------------- OK --------------------------- Recommentd 1 of 2 solutions: 1. Modify your original model not to close a loop at the reducer interface, but at a run point or Tee. 2. Open the NTL file, and delete line: Line 339: ANC 89 Line 340: ANC 89F After this modification your model was opened without issue.
