# Weft Options ### What It Does The Weft menu provides operations for manipulating the treadling (or liftplan) — the sequence that controls which treadles you press for each pick. These operations let you clear, change face, flip, reverse, mirror, and shift your treadling. Most operations work on a selected region and support both treadle mode and liftplan mode.

Weft Options

*** ### Location * **Ribbon**: Design tab > Weft dropdown menu * **Right-click**: The weft header area also offers these operations in a context menu *** ### Operations #### Clear Removes all treadle assignments in the selected weft region. Every pick in the selection becomes empty — no treadle assigned. In liftplan mode, all shaft lifts for the selected picks are cleared. Requires an active weft selection. #### Change Face Toggles every cell in the selected liftplan region: raised shafts become lowered, and lowered shafts become raised. This shows you the other side of the fabric for the selected picks — effectively flipping between the face and back of the cloth for that section. **Liftplan mode only.** If your draft uses treadle mode, this operation is not available — use Change Face on the tie-up instead. Requires an active weft selection. #### Flip Mirrors treadle assignments horizontally within the selection. In treadle mode, this swaps high-numbered treadles with low-numbered treadles — treadle 1 becomes the highest treadle, and vice versa. In liftplan mode, the shaft columns are mirrored left to right — shaft 1's lifts swap with the highest shaft's lifts. This reverses which side of the fabric's structure dominates for each pick. Requires an active weft selection. #### Reverse Reverses the pick order vertically within the selection — the first pick swaps with the last, the second with the second-to-last, and so on. Both the treadle assignments and the pick colors are flipped together. In liftplan mode, the shaft lift rows are reversed in the same way. This is the weft equivalent of reading your treadling sequence from bottom to top instead of top to bottom. Requires an active weft selection. #### Mirror Selection Appends a reversed copy of the selected picks immediately after the selection. If your selection contains picks A-B-C, the result is A-B-C-C-B-A. Both treadling and pick colors are mirrored. This is the quickest way to create a symmetrical treadling pattern. The weft automatically extends to accommodate the new picks. Works in both treadle mode and liftplan mode. Requires an active weft selection. #### Mirror All Mirrors the entire treadling, regardless of any selection. Takes all picks from the first to the last and appends a reversed copy. The weft extends to hold the mirrored picks. Works in both treadle mode and liftplan mode. Requires at least some treadling data. #### Shift Right Shifts treadle assignments one position to the right within the selection. In treadle mode, each pick's treadle number increases by one. In liftplan mode, shaft columns shift right. By default, content at the edge wraps around to the opposite side. Hold **Shift** when clicking to prevent wrapping — content at the edge is lost instead. **Keyboard shortcut**: Ctrl+Right Arrow (Cmd+Right Arrow on Mac) for wrap mode, Ctrl+Shift+Right Arrow (Cmd+Shift+Right Arrow on Mac) for no-wrap mode. Requires an active weft selection. #### Shift Left Shifts treadle assignments one position to the left within the selection. By default, wrapping is enabled. Hold **Shift** for no-wrap mode. **Keyboard shortcut**: Ctrl+Left Arrow (Cmd+Left Arrow on Mac) for wrap mode, Ctrl+Shift+Left Arrow (Cmd+Shift+Left Arrow on Mac) for no-wrap mode. Requires an active weft selection. #### Shift Up Moves all picks in the selection one row upward. Pick colors move with their treadle assignments. By default, the top pick wraps around to the bottom. Hold **Shift** to prevent wrapping. **Keyboard shortcut**: Ctrl+Up Arrow (Cmd+Up Arrow on Mac) for wrap mode, Ctrl+Shift+Up Arrow (Cmd+Shift+Up Arrow on Mac) for no-wrap mode. Requires an active weft selection. #### Shift Down Moves all picks in the selection one row downward. By default, the bottom pick wraps around to the top. Hold **Shift** for no-wrap mode. **Keyboard shortcut**: Ctrl+Down Arrow (Cmd+Down Arrow on Mac) for wrap mode, Ctrl+Shift+Down Arrow (Cmd+Shift+Down Arrow on Mac) for no-wrap mode. Requires an active weft selection. *** ### Treadle Mode vs. Liftplan Mode Some operations behave slightly differently depending on your draft mode: | Operation | Treadle Mode | Liftplan Mode | | ----------- | ---------------------------------- | ------------------------------- | | Clear | Clears treadle assignment per pick | Clears all shaft lifts per pick | | Change Face | Not available | Toggles all shaft lifts | | Flip | Reverses pick/treadle order | Reverses pick/shaft-lift order | | Reverse | Mirrors treadle numbers | Mirrors shaft columns | | Mirror | Mirrors treadling + colors | Mirrors shaft lifts + colors | | Shift R/L | Shifts treadle numbers | Shifts shaft columns | | Shift U/D | Moves picks vertically | Moves picks vertically | *** ### How to Use It 1. Select a region of the weft header by clicking and dragging 2. Open the **Weft** dropdown on the Design tab (or right-click the weft header) 3. Choose the operation you want 4. The treadling updates immediately *** ### Step-by-Step Example: Creating a Symmetrical Treadling You have a treadling sequence for one half of a pattern and want to mirror it: 1. Treadle the first half of your pattern (e.g., picks 1-12) 2. Select those picks in the weft header 3. Choose **Mirror Selection** from the Weft menu 4. The treadling extends with a reversed copy (picks 13-24 mirror picks 1-12) 5. You now have a symmetrical treadling pattern ### Step-by-Step Example: Seeing the Back of the Cloth You're working in liftplan mode and want to see what a section looks like on the back: 1. Select the picks you're interested in 2. Choose **Change Face** from the Weft menu 3. Every raised shaft becomes lowered and vice versa — the drawdown shows the back of the cloth 4. If you prefer the original, Ctrl+Z to undo *** ### Tips * **Undo works** — Ctrl+Z (Cmd+Z) reverts any weft operation. * **Selection required** — Most operations need a weft selection. Click and drag on the weft header to select picks. * **Shift key controls wrapping** — Hold Shift when clicking any shift operation to prevent wrapping. * **Colors follow picks** — Flip and Mirror move pick colors together with their treadle assignments. * **Change Face is liftplan only** — In treadle mode, use Change Face on the tie-up instead to achieve the same effect. * **Shift for exploring** — Shifting the treadling is a great way to explore pattern variations without redesigning. *** ### Quick Reference | Operation | What It Does | Shortcut | Requires Selection? | | ---------------- | --------------------------------------- | ---------------------- | ------------------- | | Clear | Remove all treadle assignments | | Yes | | Change Face | Toggle shaft lifts (liftplan only) | | Yes | | Flip | Reverse pick order (top ↔ bottom) | | Yes | | Reverse | Mirror treadle/shaft assignments | | Yes | | Mirror Selection | Append reversed copy of selection | | Yes | | Mirror All | Mirror entire treadling | | No (uses all data) | | Shift Right | Move treadles/shafts one position right | Ctrl+Right (Cmd+Right) | Yes | | Shift Left | Move treadles/shafts one position left | Ctrl+Left (Cmd+Left) | Yes | | Shift Up | Move picks one row up | Ctrl+Up (Cmd+Up) | Yes | | Shift Down | Move picks one row down | Ctrl+Down (Cmd+Down) | Yes | Add **Shift** to the shortcut for no-wrap mode (e.g., Ctrl+Shift+Right).
