Interface Overview

The Diagrammix window is built around a large canvas, with a toolbar above it, the shape library on the left, and the Inspector on the right.

The Canvas

The central area is the Canvas, where you draw your diagram. It provides an infinite scrolling workspace. Scroll or use a trackpad to move around, and hold Option while scrolling to zoom around the pointer.

The Toolbar at the top of the window gives you quick access to tools and view options:

Undo / Redo
Tools — Select, Connector, Sticky Spot Tools, Text, Pan, Zoom, Copy Style, Table, Sticky Note, Artboard, and Mind Map (PRO)
Draw menu — shapes (Rectangle, Circle, Rounded Rectangle, Round End Rectangle), Smart Shapes (Star, Block Arrow, Ring Segment), and lines and paths (Line, Arrow, Polygon, Path, Freehand)
UML menu on UML pages, and ASCII tools on ASCII pages
Align, Distribute, and Arrange menus
View toggles — Show Grid, Snap to Grid, Rulers, Smart Guides, and Show Page Layout
Autostyle menu
Icons — the icon library panel (Option+Cmd+I)
Inspector toggle and zoom controls

See Tools Overview for details on every tool.

Library

The Library is the sidebar on the left. It contains the shapes and symbols of the current notation, plus your reusable elements. Drag an item onto the canvas to add it.

Inspector Panel

On the right side is the Inspector Panel. It is organized in four tabs:

Style — fills, strokes, effects, connector options, and element colours
Text — font, size, colour, alignment, padding, and connector labels
Arrange — geometry (position, size, rotation), tables, UML, and auto-layout
Document — layers and artboards, smart connector settings, theme style, document colours, and the canvas background

The Inspector opens on Document when nothing is selected and on Style when you select something. See Inspector Panel.

Document Tabs

A document can contain several pages, shown as tabs above the canvas. See Document Tabs.

Rulers

Rulers provide measurement references along the top and left edges of the canvas.

Toggle them with the Rulers button in the toolbar
Drag from a ruler onto the canvas to create a guide line
