Problem:
The following is found in the MSG log file:
*** ERROR: CANNOT PUT REDUCER AT THIS POINT. RED IGNORED.
Why, and how to avoid?
Solution:
There are certain restrictions where an AutoPIPE component can or cannot be placed. This message simply states that a given reducer cannot be placed at a specific location. One such location would be the first component on the branch of a Tee. Remember that a tee is currently a singe node point at the center-line intersection the run piping and the branch piping. If a reducer was to be manually modeled in AutoPIPE as the first component on the branch of a Tee the following would have been displayed:
---------------------------
Error
---------------------------
E38-95: Cannot insert component after a tee. Try inserting a pipe
run point after tee equal in length to the tee leg. Then
insert component after that run point.
---------------------------
OK
---------------------------
Therefore, when importing a model that tries to perform the same task, the error message above is displayed.
Workaround:
Locate and Modify the converted NTL file, insert a pipe run point after the tee equal in length to the tee leg before the component is added.
Example:
Test.PCF was created by AutoCAD Plant 3D – 2018, when imported into AutoPIPE the program aborted the import process. In the Test.MSG file was the following error message,
RED 91 0.000 0.250 0.000
*** ERROR: CANNOT PUT REDUCER AT THIS POINT. RED IGNORED.
Open the folder where the Test.PCF file is stored and locate the newly created TEST.NTL file created by the translator:
Open the file using any text editor program (i.e. Notepadd ++, MS Word, Ultra Edit, etc..) and locate the offending reducer(s). Be warned there maybe more than one location that needs to be fixed in a model.
Notes:
1. *** (see line 338 in image above) indicates the start of a new segment
2. Notice the numbering, 89, 90, 80, 91. This is a clear indicator that the pipe is being connected to an existing node point.
3. Recall from AutoPIPE help and other WIKI pages, the first item after a tee cannot be a component (ex. reducer, valve, etc..).
Suggest the following modification, insert a Run card after the Tee connection (Run 80, line 355), refer to AutoPIPE help for details on BATCH NTL cards and format. Ensure that the new run node number does not match an existing node number in the model. The last node number in this NTL file was 135, therefore a value higher than 135 should be considered ( ex., 500). Next, divide the reducer length by two (ex. 0.250 / 2 = 0.125), use this value as the new length for the reducer and new run (see below).
Save the file and now try to Open the new NTL file in AutoPIPE.

Import process successful. Review warning messages :

Yes No Cancel

Search for added node point, (ex. 500) and make modification in the model as needed
