About
Built for Engineers,
By Engineers
Making professional engineering design accessible to everyone — no expensive licenses, no heavyweight installations.
“Every engineer, designer, student, and maker should have access to professional-grade design tools.”
Professional CAD software has traditionally been expensive, platform-locked, and resource-heavy. A single-seat license can cost thousands of dollars per year. Installation requires gigabytes of storage and specific hardware.
SableCAD was created to change that. It runs entirely in your web browser — there is nothing to download, nothing to configure, and no hardware requirements beyond a modern browser. Your projects are saved to the cloud and accessible from any device.
Purpose-Built for the Browser
SableCAD's engine is designed from day one to run natively in the browser — fast, lightweight, and accessible.
Drawing Tools
Arc Modes
Snap Types
Hatch Patterns
The 2D drawing engine delivers high-performance rendering with sub-pixel precision. It handles thousands of entities with smooth pan, zoom, and real-time snapping across 9 snap types.
The 3D modeling engine provides real-time shaded rendering with lighting, orbit camera, and mesh generation from 2D sketches via extrusion and revolution.
Both engines share a unified coordinate system and data model. Every entity type integrates fully — from snap points to hit testing to bounding boxes to 3D rendering to STL export.
The platform is designed to be lightweight, fast, and accessible on any modern browser without downloads, plugins, or special hardware.
