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.

Permaculture and regenerative farm elements seen from above and drawn roughly to scale, painted in pen and soft watercolor washes: trees and guilds, gardens and compost, water and earthworks, animals, buildings and site-analysis symbols. The same 80 subjects as the line-drawn Regenerative Farm Plan library, for planning and explaining a property. They are informal illustrations, not survey or engineering symbols.
Hand-drawn shapes for marking up a floor plan to show how a building is monitored: room, air, water and energy sensors, meters, gateways and network gear, controls, the heating, cooling and electrical equipment they watch, status markers, tags, zones and people. Includes 80 illustrations. Sensor and network markers are drawn to be left upright; equipment drawn from above can be turned to follow the plan. They are informal drawings for planning and explaining, not a drafting standard.
Pencil-style circuit symbols for planning a build the way you would on squared paper: wiring and power, resistors, capacitors and coils, diodes and transistors, switches, chips seen from above with their pin rows, logic gates, displays, sensors and meters, perfboard and connectors, and the marks written beside a circuit. Includes 80 flat drawings. Two-terminal symbols end at the middle of their left and right sides so connectors join them cleanly. They are informal sketches for notes and teaching, not a drafting standard.
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.
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.
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.
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.
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.
Pots, graters, scales, spatulas, a stove and a toaster. A small library for the foodies.
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.
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.
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.
