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
