OpenCAD Studio
What OpenCAD Studio is
OpenCAD Studio is an open-source CAD application for 2D drafting, layouts and 3D modeling. It reads and writes DWG and DXF files natively, with save targets from R14 through R2018. Browser drafting includes command-line tools, layers, object snaps, dimensions, blocks, external references, layouts and viewports. 3D tools provide solid primitives plus extrusion, revolution, sweep, loft and Boolean operations. The browser version needs no account or installation, processes local drawings on the user’s machine and downloads saves to the device. Hosted Projects can store revisions and share revocable client links. Desktop builds for Windows, macOS and Linux add native plugins, system printing, PDF output, scripts and headless automation; the published macOS package supports Apple Silicon. The WebAssembly browser build runs sequentially, and the site recommends desktop for the largest drawings. Plans include Projects Free, OpenCAD Starter at $5.84 a month, OpenCAD Projects at $12.51 a month and free OpenCAD Studio CAD under GPL-3.0.
