Export file for Modaris (Lectra); need dxf AAMA or ASTM

Rhino Rhino for Windows

I need to use simple 2D scetches, created in Rhino 4, in Modaris (Lectra). Lectra said to me, that Modaris need dxf-AAMA or ASTM. It´s supposed due to the layers.
So, how do I export files in Rhino to make it applicable for Modaris?

Not sure about ASTM, but I have a lot of success with dxf-AAMA

AAMA is really just DXF with a few layers conventions.
The main thing with exporting a aama file is the layers table:

Boundary Lines: 1
Grade/turn points:2
internal lines (draw):8
Internal Cut: 11
Notches: 4
Drills: 13
Base (grain) lines: 7
Sew lines: 14
Quality lines: 15
mirror lines: 6

The other thing to watch out for is the DXF export scheme you use. Depending on the version of Modaris you are sending to, you will have varying degrees of success with splines. So I’d suggest trying a polylines export scheme and fiddle with the tesselation parameters until you get a good balance between accuracy and density.

I tried to replicate the this but i couldnt, can you please upload a rhino file just to see how you manage to do it? i want to open the dxf aama file in clo3d and only supports this format.
thank you very much

Hi,

I know this post is quite old, but I shall be intersted to know if you had find a solution regarding import/export dxf AAMA with Rhino.

We export DXF AAMA often from Rhino.

It is well explained by @Steve_Howden , the only thing you need to add to that is make sure that once the part is finished, all layers of the part are selected and made into a DXF Block (‘block’ command in Rhino) and that block is on a layer other than any of the instruction layers (1,8, 11 etc) . So put the block onto a layer called ‘fabric’ for example.

Hello

Anyone know how to export dxf from autocad to modaris ? I follow all rules layers aama, make block but still cant open . Thanks

Hello, since this forum is easily reachable while doing DXF AAMA/ASTM related researches, I want to give my knowledge about those norms that I worked 10 years with.

AAMA and ASTM are pretty similar but AAMA is simpler so easier to replicate manually on a CAD system. Those norms was created for apparel industry, so factories and clients can exchange files without much trouble. The reality now is that programs do what they want with the norms, but well, we adapt.

The DXF should have somewhere text fields with the following information:

  • Style Name: [Project Name, better to be the same as file name]
  • Creation Date: [DD-MM-AAAA]
  • Creation Time: [HH:MM:SS]
  • Author: [System, version etc.]
  • Sample Size: [base size of garment]
  • Units: [METRIC(mm) or ENGLISH(inch")]

Each pieces should be one DXF block, the block should be named [piece name]_[size]

Each pieces should contain text fields:

  • Piece Name: [Piece name, less than 8 characters]
  • Size: [Garment Size]
  • Annotation: [Piece description]
  • Category: [Short term to categorize pieces, can be material, type of pieces…]
  • Quantity: [1,0 if one piece, 1,1 if it’s a pair of sleeve for example]
  • Material: (sometimes Fabric:) [Short code for fabric, 2 characters max)

For the layers it should be like this :

  • An empty layer called 0

  • All components of the DXF should be in a layer called 1

Then layer 1 should have those sublayers numbers:

  • 2 : corner points, segments start and end
  • 3 : curve points
  • 4 : notch point (if you draw notches as lines, set them on layer 11, but better to replace your drawing with one point on the piece outline in this layer)
  • 5 : empty and not mandatory
  • 6 : symmetry line of half pieces
  • 7 : grain lines (piece cuttin direction)
  • 8 : internal lines
  • 9 : empty and not mandatory
  • 10 : empty and not mandatory
  • 11 : internal cut
  • 12 : empty and not mandatory
  • 13 : drill/ punch (marking points)
  • 14 : net piece lines/ internal seam allowance/ piece without seam allowance (the cut outline is staying in layer 1 without sublayer)
  • 15 : ASTM layer for text notes (not the fields I mentionned earlier that stay in layer 1 without sublayers)
  • 16,17,18 never here
  • 19 : AAMA layer for text notes for Modaris. For other system, leaving them on layer 1 without sublayers is fine

Clo3d was mentionned, be careful! The default settings swap piece cut outline and piece net line (internal lines in layer 14 and cut outline in layer 1 are swaped). Some option has to be ticked in Clo3D to have the line in proper order (something like swap internal and external seam allowance)
