MDL Guidelines - Rules to define the geometry file in a MDL format

Lectra users, uploading MDL formats, can upload any MDL file according to the standards used by Lectra machines.

DXF Guidelines - Rules to define the geometry file in a DXF format

Tip: Color each layer in a different color.

1.     A boundary layer must appear in each piece.

2.     Notches, if exist, must be placed on a different layer than the boundary layer (Figure 1).

3.     Internal lines, if exist, must be placed on a different layer than the boundary layer (Figure 1).

4.     Each piece (boundary, notches, internal lines, drills, match points, piece name and annotation) is blocked once. If you need to re-block a piece, please make sure to un-block (“explode”) it first. 

Note: If you’ve already created a piece and blocked it, and then later on want to add an object to it- first explode the block, add the object, and then block all the objects back together

 

5.     Contours must be closed at each piece

6.     Rotation – User can allow the rotation of the piece inside the marker by every 45/ 90/ 180 degrees.

 

7.     Flip – User can allow the pieces to be flipped inside the marker either horizontally, vertically, both of them or no flipping at all. For example:

Horizontal , Vertical

8.     Gap – Gap is defined as half of the distance measured between two pieces in the marker. For Example:

If the Gap equals 5mm, the distance between any two pieces in the marker will be 10mm.

 

Stripes & Plaids File

 

1.     Reference lines must be blocked within a piece

2.     Reference lines must appear in one layer and on a different layer than the boundary layer (Figure 2).

3.     Fabric Parameters:

a.     X offset is measured from the left boundary of the fabric.

b.     Y offset is measured from the top boundary of the fabric.

c.      X repeat is the distance between two vertical lines on a striped & plaid fabric (Figure 3).

d.     Y repeat is the distance between two horizontal lines on a striped & plaid fabric (Figure 3).
