AAMA exchange format

Modified on Mon, 28 Sep at 4:41 PM

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, ...).

AAMA layer convention

Layer signification	Layer #		Layer signification	Layer #
Boundary_Line	1		Internal_Line	8
Turn_Points	2		Stripe_Line	9
Curve_Points	3		Plaid_Line	10
Notches	4		Internal_Cut_Out	11
Grade_Reference_Line	5		Cutter_Instruction	12
Mirror_Line	6		Drill_Holes	13
Grain_Line	7		Sew_Line	14

Extended layer convention

Layer signification	Layer #	Internal name
Markers	16	L2n_Traceurs
Contour_To_Nest	21	L2n_Contour_A_Placer
	33	L2n_Sens_Pretant
	41	L2n_Liaison_Pieces
Quality zones	50, 51, ... 56	L2n_Qzones
	90, 91, ... 96	L2n_Tzones

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
