If you create your design using a program such as Rhinoceros, CorelDraw, Adobe Illustrator, AutoCad, or TurboCAD, here are some tips for designing your parts;

• Draw all parts to be processed on the Default layer
• Draw all parts full size in black using solid lines
• DO NOT USE BLOCK DEFINITIONS!!!
• Details such as part numbers, material, depth of detail, or comments that are pertinent to the processing but not part of the detail can be put on a second layer (Details layer).
• Remove / delete all other layers
• Remove all fills and duplicated lines
• Join all lines to form closed paths
• Leave enough space around each part so that we can easily select them to create a cutting pattern.
