How do you put real CAD and BIM into a web app that people can edit, not just view, without handing your data to a closed platform?
At DevConnect 2026, our team lead shows two answers: a backend you host, and DWG editing that runs in the browser. Live, about thirty minutes.

Who it's for
- If you build software — add web CAD and BIM to your product without building the format layer yourself. Format support is plumbing. Your product is the edge.
- If you own the data — run the stack on infrastructure you control. Your models stay on storage you own, and no vendor can buy the layer that reads them and change the terms on you.
- If you build for clients — one web layer covers whatever format a project brings, on the client's cloud or your own.
What you'll see
Five recorded demos, so nothing waits on files processing. A file goes from raw IFC to an interactive model in a browser tab. You walk a combined building model in first person. Clash detection runs between a structural model and an MEP model. A shared link opens a model with no account. And a DWG is edited in the browser, then saved back. Our team lead also names what the WebAssembly SDK cannot do yet, because knowing that up front is worth more than a demo that hides it.
The two products
The session covers two products from the inWEB™ family, built by the Open Design Alliance (ODA). CDE SDK is a self-hostable backend for CAD and BIM collaboration: a REST API, async conversion across DWG, IFC, Revit and Navisworks, and a 3D viewer you host. It indexes BIM properties, so a query like 'every column on level 3 with fire rating F120' returns without loading geometry. Drawings inWEB™ SDK runs a WebAssembly core in the browser. Reading a DWG there is the baseline. The point is that a user can edit it and save back to a real DWG that opens in AutoCAD, with no server involved.
