The reality of most projects

Navisworks is powerful for projects with full BIM models from all trades. But here is the reality: most projects do not have complete 3D models. Subcontractors submit 2D shop drawings. Design teams deliver PDFs. Even on "BIM projects," the as-built reality often diverges from the model.

Helonic works with what you actually have: PDF drawings. Upload your sheets, and our AI identifies coordination conflicts, code issues, and missing information without requiring a 3D model or weeks of setup.

Many teams use both tools. Navisworks for model-based coordination during design, and Helonic for reviewing the final CD sets, shop drawings, and catching issues that slip through the BIM process.

Common use cases

Helonic

Reviewing bid documents before pricing
Shop drawing review and approval
CD set review for code compliance
Catching issues on non-BIM projects
Supplementing BIM coordination

Navisworks

MEP coordination with full models
4D construction sequencing
Design-phase clash detection
Large-scale BIM projects
Model-based quantity takeoffs

Frequently Asked Questions

What is the main difference between Helonic and Navisworks?

Navisworks performs geometric clash detection on 3D BIM models aggregated from every trade. Helonic reviews 2D PDF drawing sets with AI, flagging coordination conflicts, code compliance gaps, and missing information. The split comes down to whether your project has a complete federated model or works primarily from issued PDFs.

Does Helonic require a 3D BIM model like Navisworks?

No. Helonic works directly from 2D PDF drawings and needs no model authoring or aggregation step. That is the point: most drawing sets, shop drawings, and CD packages arrive as PDFs, and Helonic analyzes them without the setup time Navisworks requires.

Can I use Helonic and Navisworks together?

Yes, and many teams do. Navisworks handles model-based coordination during design when full 3D models exist. Helonic reviews the issued CD sets, shop drawings, and non-BIM packages, catching issues that surface after the model or on trades that never modeled their scope.

Does Helonic do geometric clash detection as precisely as Navisworks?

Navisworks is stronger for precise geometric hard-clash detection because it operates on 3D geometry. Helonic's clash detection on 2D drawings is more limited in that respect, but it adds code compliance and spec-to-drawing checks that Navisworks does not perform.

Which should a general contractor choose?

It depends on the project. A GC on a large BIM-mandated job with full trade models will still rely on Navisworks for 3D coordination. A GC reviewing bid documents, shop drawings, or CD sets without complete models gets faster value from Helonic, often alongside Navisworks rather than instead of it.
