Hi dcapestany

I would need to see the Job and Export file to see what it is doing.  If you go to Help - Send support Files, select the Job and Database files, this will create a zip file that you can Private Message me.

The Export file does not get picked up in this process so you will need to go into the MIS/CAMduct folder that you saved it in, normally :
C:\Users\Public\Documents\Autodesk\Fabrication 2015\Imperial Content\V3.01\MIS\CAMduct, obviously change the Version or Content folder so suit, the file will have a file extension of AEX, if you could also PM that file I will have a look for you.
