Loading OpenCADStudio…
The first visit fetches the WebAssembly build, which can take a little while on a slow connection. It is cached after that.
This workspace is the browser build of OpenCADStudio, an open-source CAD application by Hakan Seven and contributors, licensed GPL-3.0 and hosted here as an independent deployment. It is command-driven: type LINE, PLINE, CIRCLE, OFFSET, TRIM or FILLET, organise the drawing on layers, add dimensions, text and blocks, and set up paper-space layouts with viewports. For 3D, create solid primitives and shape them with extrusion, revolution, sweep, loft and Boolean operations.
Open a DWG or DXF file from your device and save it as DWG or DXF in any version from R14 to R2018. No account is needed, and local drawings are processed on your device. Native plugins, system printing, PDF output and scripts need the desktop app. Optional Projects storage keeps private revisions; see About & source and Pricing.
