# Tie-Up Diagonal Function

### Diagonal Button

The Diagonal button (separate from the dropdown) generates a stepped diagonal pattern across the tie-up. It opens a dialog with these settings:

**Start** Which treadle to begin the diagonal pattern from.

**Step** How many shafts to step per treadle. A step of 1 creates a simple diagonal (1-2-3-4). A step of 2 skips every other shaft (1-3-5-7).

**Treadles per Cycle** How many treadles make up one complete cycle before the pattern repeats or extends.

**Stop** The last treadle to fill with the diagonal pattern.

**Direction** Step up (shaft numbers increase) or step down (shaft numbers decrease).

If you have a selection in the tie-up, the diagonal is constrained to that shaft range.

This is a time saver for entering tie-ups where the tied-shafts on one treadle increment by stepping up or down by a specified interval.

The diagonal tool works on the entire tie-up.  The function starts with the starting treadle (defaults to no. 1), then replaces the entire tie-up of the next treadle with the contents of the first treadle, stepping the
