Drafting Style
Different approaches to drafting are used to plan cloth on different looms. In this context, we refer to these approaches as "Drafting Styles" and offer support for two different kinds of drafting styles which we call drawdown-first or threading-first approaches.
Drafting Style Options Depend on the User Selected Loom
The type of loom that you select in the Draft editor determines your options for drafting. Specifically, if you select jacquard you will only be presented with the drawdown to edit and no information about threading, tie-ups or treadling (as we assume that you do not need this information if you are working on a fully Jacquard machine.) If you select any other type of loom (harness or direct-tie/dobby) you will be given the option of the following drafting approaches:
Threading-First Drafting
In threading-first drafting, the user will see the threading, tieup, and treadling/lift-plan in full color while the drawdown remains greyed out. The drawdown will be populated by the design choices made in the other regions of the draft.
Drawdown-First Drafting
In drawdown-first drafting, the user will see the drawdown in full color with other regions of design greyed out. When the use draws upon the drawdown, the threading, tieup and treadling/lift plan information will be populated algorithmically following the process outlined in Allen Fannin's Handloom Weaving Technology
