The tools, ranked by what they do best
Helonic
That's usAI coordination conflict detection on 2D PDFs
Helonic catches coordination conflicts directly in the 2D PDF drawings most teams already issue, with no BIM or 3D model required. It flags conflicts across architectural, structural, mechanical, electrical, plumbing, and civil drawings, then gives each finding a low, medium, or high severity and exact sheet coordinates.
Best for: Coordination conflict detection on 2D PDF drawing sets, no BIM required
Autodesk Navisworks
Industry standard BIM clash detection
Autodesk Navisworks is the familiar choice for BIM coordination when the team has a complete federated 3D model. It is a strong fit for projects where each discipline models its scope and the coordination team can run clashes against model geometry.
Best for: BIM-based clash detection on projects with a fully federated 3D model
Solibri
BIM model checking and coordination analysis
Solibri checks IFC-based BIM models for rule-based issues, model quality problems, and coordination conflicts. It is most useful when the project team maintains a reliable IFC or BIM model that can be tested against rules.
Best for: Model quality checking and rule-based clash analysis for IFC-based BIM workflows
Revizto
BIM clash tracking and issue management
Revizto helps teams track clashes and coordination issues across disciplines inside a 3D model environment. It is strongest as the issue-management layer for BIM coordination teams that already have model-based review in place.
Best for: Cross-discipline clash tracking and issue management inside a 3D BIM environment
Trimble Connect
Cloud BIM coordination and clash review
Trimble Connect supports cloud-based model coordination, viewing, and clash review for teams working inside the Trimble stack. It fits BIM-driven teams that want model access and coordination in a shared cloud workspace.
Best for: Cloud BIM coordination and clash review for teams on the Trimble stack
Do you need a BIM model to run clash detection?
Traditional clash detection tools usually require a federated 3D BIM model from every discipline. Navisworks, Solibri, and Revizto are genuinely good tools when the model exists and the team keeps it current.
Many projects never get that complete model, especially renovation work, smaller commercial jobs, public work, or projects with subcontractors who do not produce BIM. Helonic runs on the 2D PDF drawings those teams already have. BIM-based tools are more thorough when a complete model exists; Helonic is the practical choice when it does not.
What types of clashes does clash detection software catch?
Clash detection software usually catches hard clashes, soft clashes, and workflow or sequence clashes. Hard clashes happen when two elements occupy the same space, soft clashes happen when clearance is missing, and sequence clashes happen when the planned order of work creates a conflict.
In 2D drawing sets, the most common coordination problems are hard clashes, clearance issues, missing dimensions, and specification conflicts across disciplines. Helonic checks these inside its 10 issue categories, including coordination conflicts, code compliance issues, missing information, constructability problems, and QA/QC items. BIM tools catch clashes in 3D geometry; Helonic catches coordination conflicts in the drawing information itself.
Frequently asked questions
What is the best clash detection software?
Helonic is the best clash detection software for teams working from 2D PDF drawing sets without a BIM model. Navisworks, Solibri, and Revizto are better fits when the project already has a complete federated 3D model.
What is the difference between clash detection and coordination review?
Clash detection usually means finding conflicts between building systems, such as ductwork crossing structure or equipment without enough clearance. Coordination review is broader: it also checks missing information, constructability problems, code issues, and inconsistencies across drawings. Helonic focuses on drawing-based coordination review with clash detection inside that workflow.
Can clash detection work on 2D drawings without BIM?
Helonic runs clash detection and coordination checks directly on 2D PDF drawing sets, with no BIM or 3D model required. That matters for projects where the issued drawings are the source of truth and a federated model does not exist.
How long does clash detection take?
Helonic completes analysis in about 30 minutes for most drawing sets. Traditional BIM clash detection time depends on whether every discipline has produced a clean model, whether the models are federated, and how many clashes need to be sorted by the coordination team.
Does clash detection software integrate with Procore or Autodesk?
Helonic has native one-click integration with Procore and Autodesk Construction Cloud, so teams can pull drawings and push RFIs. BIM clash tools often sit inside Autodesk or model-coordination workflows, but the key question is whether the findings reach the project management system.
How much does clash detection software cost?
Clash detection software cost depends on the workflow, project volume, and whether the team needs BIM coordination or 2D drawing analysis. Helonic does not publish pricing publicly, so the best next step is to book a demo and review your drawing volume and integration needs.

How this page was researched: This ranking includes Helonic, so we state that directly. We evaluated each product with the BIM requirement as the primary filter, then looked at 2D PDF capability, detection coverage, and integration with project management tools. This page reflects Helonic's September 2026 evaluation of clash detection software.
