The key difference

Solibri is rule-based and deterministic. It requires BIM models in IFC format and applies configurable rules to check geometry, spatial relationships, and data integrity. It is powerful when you have complete models, but it cannot work without them.

Helonic is AI-powered and works with PDFs. It reads your 2D drawings the way an experienced reviewer would, catching unexpected issues that no predefined rule would cover. It does not need a BIM model, setup time is minutes, and it identifies coordination problems, code violations, and missing information automatically.

The reality is that many projects do not have full BIM models. Subcontractors submit 2D shop drawings, and even "BIM projects" often rely on PDFs for final coordination. Both tools complement each other: Solibri for model-based QA during design, and Helonic for reviewing the drawings that actually get built from.

Frequently Asked Questions

What is the main difference between Helonic and Solibri?

Solibri runs deterministic, rule-based checks against 3D BIM models in IFC format. Helonic uses AI to review 2D PDF drawings, catching coordination conflicts, code issues, and missing information without a model. Solibri needs complete models to work; Helonic works from the drawings themselves.

Does Helonic require a BIM or IFC model like Solibri?

No. Helonic analyzes 2D PDF drawing sets directly and does not need an IFC model or any BIM authoring step. That matters because shop drawings and many CD sets never exist as models, and even BIM projects often coordinate from PDFs.

Can I use Helonic and Solibri together?

Yes. Solibri is well suited to model-based QA/QC during design when full IFC models are available. Helonic reviews the 2D drawings that get built from, including trades and packages that were never modeled, so the two cover different stages of the same project.

How does rule-based checking differ from Helonic's AI analysis?

Solibri applies configurable rules and returns consistent, predictable results for the conditions those rules define. Helonic's AI reads drawings more like an experienced reviewer and can surface issues no predefined rule anticipated, at the cost of the strict determinism a rule engine provides.

Which should a team without full BIM models choose?

Helonic. Solibri's value depends on having complete IFC models, so teams working primarily from 2D PDFs get little from it. Helonic is built for exactly that case and sets up in minutes rather than days.
