UI Flow
Pages, phone screens, buttons, fields, menus, toggles, cards, touch gestures and AI chat shapes, for sketching how a website or app flows from screen to screen.
Shape libraries
Various shapes to drop into your diagrams. Browse as much as you like. Every library is free. You need a SimpleDiagrams account to download one, and SimpleDiagrams 5 for Mac to use it.
Hobby Electronics
Hand-drawn shapes for sketching an electronics bench or a simple build: test instruments, breadboards and boards, common components, batteries, sensors and motors, cables and connectors, soldering gear, hand tools and the workspace. Includes 100 illustrations, flat and isometric; they are informal drawings of generic parts, not schematic symbols or any maker's products.
Value Stream
Shapes for value stream mapping: processes, data boxes, inventory, shipments, push and pull arrows, kanban and the kaizen burst. Use them to help your team get products from creation to customer as quickly as you can.
Azure
Hand-drawn versions of the Microsoft Azure service icons, in Azure's own colours. Use them to sketch a cloud architecture that looks like a conversation rather than a finished blueprint.
Green Walls
Hand-drawn shapes for designing, installing and maintaining green walls: 50 indoor and outdoor plants seen as they grow on a vertical wall, and 30 installation items from planter panels and drip lines to sensors, lights and access. Each plant carries its botanical name, growth habit and typical light and water needs as shape data, with fields for cost, quantity and status. Informal planning drawings, not plant-care advice or any manufacturer's equipment.
Insurance
Hand-drawn shapes for mapping claims, underwriting and customer journeys, and for explaining cover: the people involved, policies and payments, the things people insure, and the losses they claim for. Includes 42 illustrations; they are informal drawings, not any insurer's forms, branding or legal symbols.
Cooking #1
Pots, graters, scales, spatulas, a stove and a toaster. A small library for the foodies.
Data Centers and Networking
Shapes for planning, building and explaining data centers and computing: racks and servers, GPUs and AI clusters, networking and storage, cooling, power and the data hall, plus diagrams of how AI models are trained and served. Includes 80 illustrations, half flat and half isometric. All informal illustrations, not vendor products or engineering symbols.
Home Energy Efficiency
Shapes for planning home energy assessments, monitoring and upgrades, in new builds and retrofits: testing tools such as blower doors and thermal cameras, insulation, air sealing and glazing, heat pumps and efficient appliances, solar, meters, reports and people. Includes 80 illustrations, some flat and some isometric; they are informal illustrations, not engineering drawings or rating-scheme symbols.
Regenerative Farm Isometric
Isometric sketches of permaculture and regenerative farm elements: trees and plantings, gardens and compost, water harvesting and earthworks, animals, buildings, tools and people. Includes 80 illustrations for planning and explaining a property; they are informal illustrations, not engineering drawings.
Regenerative Farm Plan
Permaculture and regenerative farm shapes, seen from above and drawn roughly to scale: trees and guilds, gardens and compost, water and earthworks, animals, buildings and site-analysis symbols. Includes 80 illustrations for planning and explaining a property; they are informal illustrations, not survey or engineering symbols.
Solar & Battery Sites 2
Shapes for solar PV and battery storage sites, from panels and DC collection through inverters, battery systems, grid connections and site operations. Includes 80 illustrations for informal planning and communication; these are not standard electrical or safety symbols.
Important: These shapes are for informal planning, presentations and communication only. They are not standardised electrical symbols and are not intended for electrical schematics, engineering specifications, installation or maintenance instructions, or compliant safety signage. Illustrations do not establish that a system is safe or meets applicable standards.
