Notch trouble in AAMA DXF conversion

Hi all,
I've been unable to view notches when using AAMA DXF conversions. I tried every Export Option I can find. Interestingly when I try Standard DXF process (so Notch Table is greyed out) the notches are visible... I've tried using Export with *.Rul... I've tried angling the notches... I've tried changing notch info in PDS... all these and more didn't work. I'm wondering if the P-Notch Parameter table has anything to do with it but I've never modified this after 20 years of using Gerber...
I also run an Autocad system so I can view how the DXF conversion look. 
Please find attached images of:
-DCU Export page example image
-zoom in where notches should be on graded piece.
Please help if you can.
Best regards

    It depends. If you are using AutoCAD that is Standard DXF and it will handle the notch data differently from ASTM notch data which becomes a system generated notch defined by notch depth, width etc.

    Are you receiving both types of dxf files? Open the file in question in Notepad and search on the word "unit" - if you have this in the file, search on "Author". ASTM files can import in notches and they will display ONLY when you have notches defined in the P-Notch Parameter table in AccuMark with a value.

    If you search in Notepad and do NOT see a "unit" then the file is ACAD dxf which is Standard DXF and DCU options can be used to scan geometry perimeter and convert the internal lines to system generated notches.
  • Hi Kathy, Thanks for your prompt reply. I am back in my work space tomorrow so I'll have a go then.
    Many thanks
