There are two types of Element categories in DesignShop, Wireframe and Expanded.
Wireframe is recommended when using Melco machines because it makes editing and removing digitizing errors significantly easier.
Check your elements list to see if your design is saved as Expanded, if the elements are listed as anything else it is saved as Wireframe.
For a list of digitizers who provide Wireframe please see our knowledge base article on List Of 3rd Party Digitizing Companies.
