- Which CAD do you use? Cadasio has add-ins for five CAD systems. TwinWorks reads exported files, and STEP is in beta.
- Who approves a release? TwinWorks has review, approval and revisions. Cadasio states roles and ownership.
- What must the floor send back? Cadasio emails a form. TwinWorks keeps step records and exports reports.

Questions
What is the difference between TwinWorks and Cadasio?
Cadasio turns a CAD model into an interactive 3D presentation that an author builds step by step in a browser designer. TwinWorks is work instruction and manual software: AI drafts the text from your PDF or Word manuals, authors set each step on the 3D model, experts approve it, and operators follow it in a browser and send back what they did.
How much does Cadasio cost?
Cadasio publishes its prices. On 10 November 2026: Personal, free, with 3 projects of 10 steps each, Professional at $85 per user a month or $850 a year, and Premium at $2,000 per user a year. Viewing a published project is free.
Which CAD files do they read?
Cadasio has add-ins for SolidWorks, Autodesk Inventor, Fusion 360, Solid Edge and Onshape, and takes STEP and OBJ uploads. TwinWorks imports GLB, self-contained GLTF, FBX, OBJ and USDZ, with STEP and STP import in beta. It has no CAD add-in.
Does Cadasio use AI?
Cadasio Studio, announced in November 2026, uses AI to restyle step images, for example as photorealistic pictures. Cadasio states no AI for writing steps or text. In TwinWorks, AI drafts procedure text from reference PDFs and an assistant proposes part moves and views that the author reviews.
What happens when the design changes?
In Cadasio, the CAD add-in updates the project: new parts are added and geometry changes carry through every step. TwinWorks shows which procedures and manual sections use the changed part, and your experts review and approve each update.
Where do these facts come from?
From Cadasio’s own pages, read on 10 November 2026: pricing, features, CAD add-ins, security, publishing, versions, forms, the Explode tool and Cadasio Studio. We make TwinWorks. Features and prices change, so confirm with Cadasio.
