HELiOS

HELiOS is a self-hosted product-data and document system for engineering teams whose work revolves around CAD-linked articles. It suits organizations that need formal revision, release and access controls across departments. Choose it for governed product information; look elsewhere if you need cloud delivery, broad operating-system support or transparent prices.

Overview

HELiOS organizes information created while products are designed, released and revised. Drawings and geometries stay connected to articles, while Office documents, emails and other files can be attached to the same product records. Version and release management make earlier information retrievable, which is valuable when engineering changes must remain traceable.

The system is designed for communication beyond the CAD department. Rights-based access, checklists and workflow technology help coordinate controlled handoffs. HELiOS can also serve as a managed data-flow component between CAD, PDM and ERP systems, so it fits companies building a connected product-information process rather than teams seeking simple file storage.

Key features

CAD and document control

Release, derivation, versioning and search functions apply to drawings and geometries linked to articles. This gives engineering groups a structured way to manage revisions and find previous states. CAD file viewing is included, as are revision control and approval workflows. Office files, emails and other documents can be associated with products, keeping supporting material alongside technical records.

Integrations and extensions

HELiOS connects with HiCAD, AutoCAD and Inventor, and offers EPLAN integration for ECAD work. Microsoft Office product information and documents can flow into the managed product model. Modular add-ons include Spooler, Internet Server, replication management and VaultServer, allowing deployments to extend beyond the core system as requirements grow.

Licensing and support

Standalone, network and commuter licenses are activated through the ISD License Manager. Weekday phone support is offered, while software-maintenance-contract customers receive hotline support and updates. Those terms favor organizations prepared to operate a formal, maintained installation.

Pricing

HELiOS is paid software with custom pricing. The HELiOS PDM/PLM plan has no published price and includes Viewer, Office and Engineer base modules, with add-on modules available. That modular structure can match different roles, but buyers must obtain a quote before comparing total cost, including any extensions and support arrangements.

There is no free plan. A small-company “Out of the Box” introduction targets companies with up to five engineering workstations and no connection to systems beyond CAD. It is therefore a sensible entry point for a compact engineering operation, while organizations needing ERP links, replication or broader deployment should assess the full PDM/PLM configuration instead.

Platforms

HELiOS is deployed on premises and supports Windows. The HELiOS 2025 client requires a 64-bit processor, at least 4 GB of RAM, 2 GB of free disk space, and Windows 10 or Windows Server 2016 or newer. Self-hosting provides control over product data but puts infrastructure and Windows administration on the customer; teams seeking browser-first or cross-platform access should consider alternatives.

Who it's for

HELiOS is a strong fit for mechanical and electrical engineering organizations managing CAD revisions, approvals and related business documents across departments. It also suits companies that need a controlled bridge between CAD, PDM and ERP, or that expect to add capabilities through modules. It is less appropriate for a small, non-engineering group that only needs shared documents, and for teams that cannot support an on-premises Windows environment.

Pros and cons

• Pros: CAD drawings and geometries remain tied to article records, with release, derivation, versioning and search.
• Pros: Approval workflows, checklists and rights-based access support controlled cross-department processes.
• Pros: HiCAD, AutoCAD, Inventor, EPLAN and Microsoft Office connections cover common engineering information flows.
• Pros: Modular add-ons and ERP-oriented data flow support expansion beyond a basic CAD repository.
• Cons: On-premises Windows deployment excludes teams wanting cloud-native or non-Windows operation.
• Cons: Custom pricing and no free plan make budgeting and low-risk evaluation harder.
• Cons: The small-company package is limited to five engineering workstations and CAD-only connectivity.

Alternatives

Consider OpenBOM when a freemium, web-capable option and a free tier for up to 2,000 records matter more than HELiOS's on-premises workflow. Choose MechWorks PDM if you want self-hosted, web and API access with a free trial and reseller implementation support.

OpenText Documentum Content Management is a better direction for broad document management across Android, iOS and the web, with retention, redaction, process automation and Microsoft 365 integration. Adept suits organizations wanting an on-premises named read-only seat at $12.00 per month, with web search, browsing and 2D/3D viewing.

Pick ENOVIA PDM for a web and self-hosted platform with a 3DEXPERIENCE cloud evaluation offer at $345.00 per contact per quarter and 24/7 support. Vistapoint PDM is preferable when cloud delivery, CAD integrations and a $24.00 monthly read-only seat are priorities. ProjectWise is the alternative for web/Windows infrastructure workflows with annual Bentley subscriptions. RAM Elements is a narrower Windows engineering tool rather than a like-for-like PDM replacement.

Verdict

Choose HELiOS if your engineering organization needs article-centered CAD and document control, formal approvals and a governed path between CAD, PDM and ERP. Its main advantage is the depth of revision and release management around product records. Look elsewhere if you require cloud deployment, non-Windows clients, a free tier or upfront pricing.
