5 Alternatives to Creo View for Sharing CAD Files Without PTC Windchill

Creo View Web is served through Windchill, PTC's PLM. Here are 5 browser-based alternatives to share CAD with clients and suppliers, no PLM needed.

Creo View is PTC's CAD visualization viewer. Creo View Express is free but desktop-only (Windows) and reads PTC's own representations. Browser-based viewing — Creo View Web — is served *through* Windchill, PTC's PLM platform: the Windchill help center describes Creo View as launched from Windchill, with license validation handled by Windchill Visualization Services. In practice, browser access assumes your organization runs Windchill and that the person opening the model is a Windchill user. If you don't run Windchill — or you need to share with an external client or supplier who never will — you need a viewer that works from a plain browser link. Here are five, ranked by use case.

At a glance: 5 Creo View alternatives compared

1. OmniView 3D — no PLM required, browser-first

OmniView 3D reads STEP, IGES, GLB, FBX, OBJ and STL with no Windchill and no Creo license. You upload the file (or a STEP export of a Creo .prt/.asm), and OmniView builds an interactive viewer behind a link you send by email or chat. Models are private by default, the link is revocable, and hosting is in the EU (AWS eu-west-1, Ireland). A free plan covers occasional sharing; Pro is $59/month excl. tax. It is the closest match to "Creo View Web, but without the PLM" — see the PTC Creo file viewer guide for the Creo-to-STEP workflow.

2. Autodesk Viewer — free, broadest format list

viewer.autodesk.com opens STEP, DWG, RVT and over 50 formats for free, which makes it a quick way to show a Creo STEP export to an external stakeholder. The trade-offs: private, revocable sharing is limited, and models sit on Autodesk's US infrastructure — a point to weigh for confidential or GDPR-sensitive parts.

3. 3DViewerOnline — multi-format web viewer

3DViewerOnline opens STEP, IGES and STL in the browser with no PLM, and offers private sharing on its paid plans. It is a reasonable middle ground; compare it with the browser alternatives round-up before committing.

4. eDrawings — if your subcontractors live in SolidWorks

eDrawings is Dassault's free viewer. Since the 2018 release it opens STEP files in addition to SolidWorks parts, so a Creo STEP export opens fine. The catch: it is a desktop install (Windows/macOS), not a browser link — your recipient downloads and installs an .exe before they can look at the part.

5. Onshape — cloud CAD with a built-in viewer

Onshape imports STEP and generates review links in the browser. Note the plan structure: its free plan makes every document public (viewable and copyable by any Onshape user), and private documents require the Professional plan at $2,500/user/year. It fits teams that also want cloud modeling — less so a one-off share with a client. For a dedicated comparison, see Onshape alternatives for private 3D sharing.

Why a STEP export is the common thread

Every alternative above relies on one habit: export the Creo part to STEP (ISO 10303), the neutral CAD standard published since 1994 that preserves exact B-Rep geometry and that every CAD system reads. Creo exports STEP in under a minute (File → Save As → STEP). This is not a niche concern: the global 3D CAD software market was worth about $10.38 billion in 2022, projected to reach $17.34 billion by 2030, and most of that value depends on tools exchanging neutral files cleanly. Once you have a STEP, any of these five opens it — the only questions are whether you want a browser link or a desktop install, and whether sharing stays private.
