Drawdown

We use the term drawdown to describe the part of the draft that represents the structure of the resulting cloth.

A single cell in the drawdown represents a location at which the warp and weft cross.

When interpreted on a loom, each black cell represents a place where the loom lifts the warp end (allowing the weft pick to travel under that warp). We refer to this movement as a "warp raised." In white cells, the weft is left lowered, allowing the weft to travel over the warp end. We refer to this as a "warp-lowered" cell.

A note to experienced drafters​

We use the drawdown as the default draft representation in AdaCAD.

You can view the associated threading, tie-up, and treadling diagrams by changing your default loom type and opening the draft detail viewer, or, using operations that generates new "drawdowns" each of which corresponds to the pattern used in your threading, tie-up, and treadling.
