Read docsDrawing features in hours. Not months of development.
Building a drawing engine is a multi-year project. Formats, precision, performance, measurement, markup, revisions. You install a package instead, and spend your time on the part your users actually pay for.
npm i @rasterex/viewer, point it at a DWG, IFC or PDF. A drawing is on screen in your own app.
Activate tools, listen to events, store markups and measurements where your project data already lives.
Your UI, your brand, your infrastructure. No drawing engine to build, maintain or hire for.
