Foreword


AAMA defines the structure of a DXF to facilitate part exchange between applications

Each part is a block.

Each layer has a defined meaning 

Part information is defined by 'system texts'


AAMA might be extended to transfer additional information (quality zone, analytical code, ...)

Note 


Some small differences might exist between AAMA and L2N file generation 


Using tool configuration, it is possible to manage additional layers

As an example, drill hole #2 can be sent to layer 15
