Scientific Research & Simulation
Secure, Fast & Cloud-Based
Researchers use CAD to design lab equipment, simulate physical phenomena, and model biological or mechanical systems. CAD integrates with analysis tools for structural, thermal, and fluid dynamics simulations. It also supports 3D scanning and replication of complex geometries.

SCIENTIFIC RESEARCH & SIMULATION CAD VIEWER
Review engine parts, body assemblies, and supplier-submitted CAD files without installing heavy desktop software.
View any scientific research & simulation CAD file in three simple steps — no signup, no software.
Drag & drop or browse to upload your CAD file. We support 50+ formats.
Instantly view your 3D model with measurement tools, cross-sections, and annotations.
Generate a shareable link or convert to another format with one click.
In scientific research & simulation, 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.
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.
Used for exchanging precise 3D engineering geometry and assemblies across tools and suppliers.
Common for surface and geometry exchange when teams collaborate across different CAD systems.
Useful for mesh-based previews and review workflows (especially prototyping and fabrication contexts).
Helpful for inspecting boundary-representation solids and engineering geometry online.
Useful for polygon-based model inspection and technical visualization workflows.
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.
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.
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.
No software installation required (review in browser)
Supports common exchange formats (STEP/IGES) plus mesh formats (STL/PLY/OFF) and solids (BREP)
Fast online preview for technical review discussions
Private uploads with automatic 7-day deletion
Better access for non-CAD stakeholders across the workflow

Answers for teams evaluating browser-based CAD review with Marathon OS.
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.
Yes. Marathon OS lets you upload and preview STEP and IGES files in a browser—useful when reviewers do not need full authoring tools.
Commonly: Biologists, Graduate Students, Policy Makers. These roles often need visibility for decisions, reviews, or execution, even if they don’t edit CAD.
The viewer messaging on Marathon OS states uploads up to 300 MB. For larger datasets, teams typically split assemblies or use simplified review files.
Marathon OS states uploads are private and automatically deleted after 7 days, which helps reduce long-term exposure of shared files.
Yes. The viewer is positioned as browser-based, so teams can preview models without installing desktop software or browser plugins.
Yes. A single 3D preview helps keep discussions aligned and reduces time spent sharing screenshots or exporting multiple view files.
The site positions the viewer as free to use for online preview, with demo and product options available depending on team needs.
Everything you need to design faster, smarter, and with more impact.
Open CAD files in your browser, inspect 3D geometry quickly, and give every stakeholder easier access to the models they need.
