| Area | Where | What it holds |
|---|---|---|
| Top bar | top | The menu bar, the document title, the template library and leather library buttons, the side-panel button and the light/dark theme button. |
| Tool rail | left | One button per tool, in groups: selection, drawing, annotation, construction, stitching and leather, images. Hover a button to see its name and key. |
| Canvas | middle | The drawing, on a dotted grid, with rulers along the top and left. |
| Side panel | right | Sections that follow what you are doing (see below). |
| Memo | under the canvas | Notes about the project, saved with it. Click Memo to open or fold it. |
| Status bar | bottom | Cursor position, zoom, unit, grid snap, shape and selection counts, the selection's size and lengths, and messages and hints from the tools. |
The document title
The file name is shown in the top bar. A dot after it means there are changes not yet saved to a file. When saving needs you, the title says so: Allow saving (click it to let the browser write the file again after a reload), Changed elsewhere, or a failed save. See Files and saving.
The side panel
The side panel shows what the current task needs:
| Section | When it shows | Contents |
|---|---|---|
| Properties / the tool's name | always, first | With the Select tool: the selection's position and size, alignment, and the leather of leather-filled shapes. With another tool: that tool's options. |
| Pricking irons | with the Stitching tool, or when holes are selected | The irons and their blade counts; the Pricking irons dialog button. |
| Layers | always | The layers of the drawing. |
| Line types | always | The 40-entry line-type palette. |
Each section folds with the arrow on its header. View ▸ Side panel shows or hides the panel; View ▸ Pin side panel keeps it open. With the side panel hidden, tool options appear in a bar above the canvas and the position-and-size palette floats over the canvas.
The status bar
From left to right:
X / Y: the cursor position in the drawing.
Zoom: the zoom level in percent.
Unit: mm or in.
Grid snap: on/off: click to switch grid snapping (see Snapping).
Shape count and selection count.
Selection summary: its width × height, the length of a single line, the radius and sweep of an arc, the angle between two joined lines, the total length of the selected lines, the number of holes, and a single shape's id.
While drawing, the summary's place shows the shape being drawn instead:
- a line: its length and angle (from the right, turning clockwise as the Y axis points down; counter-clockwise with Invert the Y axis in Options), and its angle to the line it starts on (as the Line tool's Relative angle measures it);
- an arc: its length, radius and sweep;
- a circle: its radius (R), diameter (Ø) and circumference;
- an oval or a rectangle: its width × height and its perimeter (the length all round);
- a Bézier curve: while you place the first handle, its length and angle from the start; while you place the second handle, the length and angle of the line from the first handle; while you place the end, the curve's length and the end's handle (its length and angle from the end point).
Shapes of a fixed size (the Diameter, Width and Height options) are measured while they follow the pointer, and a tangent circle, arc or line while it is previewed. The readout goes when the shape is drawn, when you press Esc, or when you change tools.
Text warnings (amber), while a text is edited: its font is missing, or the font lacks some of its characters (see Text).
Message: the current tool's instructions, or the result of the last command (for example "Fixed 3 issues in 2 passes."). Warnings such as "The active layer is hidden." appear here.
Theme
The sun/moon button in the top bar switches between light and dark. The canvas follows: white in the light theme, black in the dark one. Each line type has a colour for each background (see Line types), so lines stay easy to see.
