What is the difference between a Standard DXF File and an ASTM/AAMA DXF File?
ASTM/AAMA DXF is a file format developed by the American Apparel Manufacturers Association in an attempt to solve the difficulties of using DXF files.
DXF is the most commonly used format for the exchange of drawing files.
But if the ASTM/AAMA DXF format is used, files can contain many patterns either nested, or non-nested, in a form which can be easily processed and used by plotter operators.
ASTM/AAMA DXF files allow for graded nests as well as grade rules (with tables) to be imported/exported as part of the file. Standard DXF files does not have this ability.
Take a moment to review the import/export options found in DCU (View|Options) to get a better understanding of the differences between ASTM/AAMA DXF files and Standard DXF files.
I hope this is clear and helpful.
