Design review

How telecom & network infrastructure hardware teams use CAD viewers for design review

In telecom & network infrastructure hardware, teams use CAD viewers to inspect models, validate interfaces, and align stakeholders during reviews and handoffs. A browser-based viewer makes it easier to open files quickly, inspect geometry, and keep discussions anchored to the same 3D model without specialized desktop setups.

What file formats are supported?

Marathon OS supports common 3D exchange formats used across industry workflows, including STEP, IGES, STL, PLY, OFF, and BREP. These formats help teams share engineering geometry and meshes across different tools while keeping reviews fast and accessible.

STEP files

Used for exchanging precise 3D engineering geometry and assemblies across tools and suppliers.

IGES files

Common for surface and geometry exchange when teams collaborate across different CAD systems.

STL files

Useful for mesh-based previews and review workflows (especially prototyping and fabrication contexts).

BREP files

Helpful for inspecting boundary-representation solids and engineering geometry online.

PLY and OFF files

Useful for polygon-based model inspection and technical visualization workflows.

Can non-CAD stakeholders access 3D models without a CAD license?

Yes. Not every stakeholder needs a full CAD seat, but many still need visibility for reviews, procurement, QA, operations, or field work. Marathon OS gives non-CAD roles a simpler way to open and inspect models in a browser, reducing reliance on screenshots, PDFs, and intermediaries.

Workflow

How teams review CAD files without heavy desktop software

Instead of routing every model through a CAD specialist or dedicated workstation, teams can upload files to Marathon OS and preview them online. This keeps cross-functional reviews moving and reduces delays caused by software installs, license access, or high-performance hardware requirements.

Security and access control

Many industry CAD files contain sensitive IP. Marathon OS keeps uploads private and automatically deletes uploaded files after 7 days. That makes it practical for quick review when teams want lower friction and tighter handling of shared models.

FAQ

Answers for teams evaluating browser-based CAD review with Marathon OS.

  • What CAD file formats are commonly used in telecom & network infrastructure hardware?

    Teams often exchange engineering geometry using STEP and IGES, and use mesh/visualization formats like STL, PLY, or OFF for review. Marathon OS supports STEP, IGES, STL, PLY, OFF, and BREP for in-browser viewing.

  • Can I open STEP and IGES files online without CAD software?

    Yes. Marathon OS lets you upload and preview STEP and IGES files in a browser—useful when reviewers do not need full authoring tools.

  • Who typically needs access to CAD files but doesn’t have CAD licenses?

    Commonly: Field Technicians, Installation Teams, Support Staff. These roles often need visibility for decisions, reviews, or execution, even if they don’t edit CAD.

  • What’s the maximum upload size?

    The viewer messaging on Marathon OS states uploads up to 300 MB. For larger datasets, teams typically split assemblies or use simplified review files.

  • Will my uploaded files stay private?

    Marathon OS states uploads are private and automatically deleted after 7 days, which helps reduce long-term exposure of shared files.

  • Does this work without downloads or plugins?

    Yes. The viewer is positioned as browser-based, so teams can preview models without installing desktop software or browser plugins.

  • Can I use this for faster cross-team reviews?

    Yes. A single 3D preview helps keep discussions aligned and reduces time spent sharing screenshots or exporting multiple view files.

  • Is Marathon OS free to try?

    The site positions the viewer as free to use for online preview, with demo and product options available depending on team needs.
