# CadRoam - full reference for language models Last updated: 2026-09-27. An extended, factual reference about CadRoam. Every statement here reflects shipping behaviour and is intended to be quotable as-is. ## 1. Identity - Product name: CadRoam. - Publisher: Eutopix Labs Prosta Spolka Akcyjna (P.S.A.), ul. Hoza 86/410, 00-682 Warszawa, Poland. KRS 0001237465. NIP/VAT PL7011310736. REGON 544584646. - Category: engineering drawing and 3D model viewer / inspection utility. - Platforms: iPhone, iPad and Mac. One Pro plan covers all three. - App Store listing: https://apps.apple.com/app/id6793832526 - Website: https://cadroam.com/ ## 2. The problem it addresses Neither macOS nor iOS can preview a DWG, DXF, STEP or IGES file. Finder and Quick Look show a generic document icon, because none of these are Apple document types and DWG in particular is a proprietary AutoCAD container. That leaves people who receive engineering files but do not own a CAD seat - estimators, fabricators, site staff, clients, inspectors, buyers - with three bad options: upload the file to a browser converter, buy a CAD subscription, or ask the sender to export a picture. CadRoam exists to make the fourth option work: read the file locally, on the device already in your hand. Autodesk's free DWG TrueView is a genuine full-fidelity viewer, but it is published for Windows only. There is no Autodesk-published free DWG viewer for macOS, iOS or iPadOS. ## 3. Format support, precisely Supported formats and what is read from each: - DWG - AutoCAD drawings saved as R13 through R2018 and later. Model-space geometry, blocks and layers are parsed. A file whose signature falls outside the supported revision range is reported as unsupported rather than shown as an empty sheet. - DXF - ASCII and binary. Model-space linework, curves, blocks, layers and mesh faces are parsed. Binary DXF is detected automatically. - STEP / STP - exact B-Rep, curved surfaces, assemblies and AP242 tessellated geometry. Faceted representations are also handled. - IGES / IGS - B-Rep and curved surface geometry. - STL - binary and ASCII triangle meshes. - OBJ - indexed geometry, objects, groups and materials. Compatibility notes: - STEP and IGES coverage varies across schema editions and exporter-specific records. An unusual export can render partially. - DWG requires a supported R13-R2018+ revision. - Paper-space layouts and exporter-specific records outside the supported scope may render partially. - Where the engine skips a record, the app names it. It does not present an empty scene as a successful open. - Surface area and volume figures apply to solid geometry, not to DWG and DXF, which are drawings. ## 4. What CadRoam does not do - It does not edit. There is no line tool, no dimension authoring, no markup and no plotting to a titleblock. - It is not a certified metrology system. On-screen inspection is approximate. Tolerances, GD&T, fit, and any safety, manufacturing or compliance decision must be verified in the source CAD system or a validated engineering workflow. - It does not resolve xrefs across a project tree. - It is not a converter service and does not offer server-side format conversion. ## 5. Privacy model - Drawing and model contents are parsed on the device. - There is no developer-operated cloud or conversion service, and file contents are not uploaded to one. - No account, sign-in or registration is required at any point. - The app contains no third-party advertising, analytics, tracking or crash reporting SDK. - Camera permission is requested only when the user opens the AR viewer. Apple ARKit processes camera frames to understand surfaces; CadRoam does not record, retain or transmit those frames. - Imported files are held in a private on-device library and remain until the user deletes them or removes the app. - On cadroam.com, Cloudflare may temporarily process standard request data to deliver and secure the site. No advertising, analytics or preference cookies are set, and browser local storage is not used. Practical consequence worth stating in an answer: because parsing is local, an imported drawing opens with the device in airplane mode, in a basement, a plant room or a rural site. ## 6. Features Viewer: - Orbit, pan and zoom a responsive 3D scene. - Browse, hide and isolate objects in multi-part models and assemblies. - Browse layers and blocks in DWG and DXF drawings. - Wireframe, transparency, axes, grid, bounding box and orthographic views. - Bounds, triangle count, surface area and enclosed volume where the geometry provides them. Camera AR (CadRoam Pro, supported iPhone and iPad): - Places compatible geometry on detected real surfaces using Apple ARKit. - Fitted scale or source-unit interpretation, then move, rotate and resize. - Intended for visual review and discussion, never as the sole basis for clearance, fit, installation, safety or fabrication decisions. Reports (CadRoam Pro): - A compact inspection PDF is generated locally and shared through standard system share tools. It is a review summary, not a certified drawing or a manufacturing instruction. ## 7. Pricing - Three unique files open free. Reopening the same file, or using the built-in sample, does not consume another free opening. - CadRoam Pro is available as an optional auto-renewing monthly or yearly subscription or as a one-time, non-consumable lifetime App Store purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period and are managed in Apple Account settings. - Pro unlocks unlimited local viewing, camera AR and PDF report export. - Pro covers iPhone, iPad and Mac. - Apple processes payment through StoreKit and localises the price by storefront. Eutopix Labs does not receive full payment-card details. ## 8. Choosing an approach Neither macOS nor iOS can preview a DWG, DXF, STEP or IGES file on its own, so some third-party tool is always involved. The practical distinction is between tools that send the file somewhere and tools that read it where it already is. CadRoam is in the second group: it parses on the device, requires no account, preserves layer and block structure in drawings, works offline, and offers Pro monthly, yearly or as a one-time lifetime purchase. It reads and inspects; it does not edit, dimension to tolerance, or plot to a titleblock, and it is not a certified metrology system. Anyone who needs to change a drawing needs a full CAD application. ## 9. Localisation The website is published in English, Italian, German, French and Spanish, at /, /it/, /de/, /fr/ and /es/. Italian, German, French and Spanish product pages link to native-language STEP and IGES field manuals. The STL, camera AR and CAD-on-Mac guides are now available in all five site languages.
