View and Check IFC Models in the Browser

Upload any .ifc file and inspect the 3D model with no install and no Revit license. The agent indexes the full model so you can take off quantities, check properties, and validate model data against the drawings and specs on the project.

Open the model without a plugin or a CAD seat

Drop a .ifc or .ifczip file into Nomic and inspect it in the browser. Orbit, pan, and zoom the geometry, then click any element to read its properties, level, and relationships. IFC2x3, IFC4, and IFC4x3 are supported, including infrastructure and alignment entities.

  • No Revit, Navisworks, or browser plugin required
  • Click an element to see properties, quantities, and spatial relationships
  • Anyone with project access can view the same model in the same space
Ask for counts, schedules, and property checks
02 / Agent on the model

Ask for counts, schedules, and property checks

When an IFC is uploaded, Nomic extracts elements, properties, levels, spaces, materials, and relationships into structured tables. The agent writes SQL over those tables and returns real numbers from the model, not a summary of the geometry.

  • Quantity takeoff by category and level
  • Room and material schedules from IfcSpace and layer data
  • Missing fire ratings, COBie fields, and classification codes
Data checks in the browser, not a rule-set engine
03 / Viewing vs checking

Data checks in the browser, not a rule-set engine

Viewing shows geometry and properties. Checking asks whether the model is correct: required properties populated, naming and classification on standard, model data matching the drawings and specifications. Nomic covers the data and document side, and the IFC Model Checker page goes through what that validation pass covers in detail. Rule-set or IDS schema validation of the Solibri kind is a different job.

  • Check property sets, fire ratings, quantities, and COBie fields in the browser
  • Compare model data against drawings and specs in the same project space
  • Nomic is the data and document check. Dedicated rule engines handle IDS and clash rule sets
Outcomes

What teams get from this workflow

No software to install

Open an IFC in the browser and share the project space. Reviewers do not need a CAD license to inspect the model or read agent answers.

Answers from the model tables

Counts, areas, and property values come from extracted IFC tables, so you can trace a number back to an element instead of trusting a generated summary.

Same space as the documents

The model sits next to drawings, specs, RFIs, and email, so a fire-rating check can include the door schedule PDF, not only the IFC.

FAQ
Questions about this AI for BIM & IFC models workflow

Answers to common questions about this workflow.

What IFC file formats does Nomic support?

Nomic supports .ifc and .ifczip files in IFC2x3, IFC4, and IFC4x3, including infrastructure and alignment entities. Drop the file in and it indexes automatically.

Do I need Revit or any other BIM software to use the IFC viewer?

No. Nomic runs in the browser. Anyone with a link to the project space can view the 3D model and get agent answers, with no Revit license, Navisworks, plugin, or install.

Can I view a model exported from Revit?

Yes. Export an IFC from Revit (File > Export > IFC) and upload it to Nomic. Revit property sets, quantities, levels, and rooms are extracted and queryable. Native .rvt geometry support is on the roadmap.

How does the Nomic agent answer questions about an IFC model?

When an IFC is uploaded, Nomic extracts the model into structured tables (elements, properties, levels, spaces, materials, relationships). The agent writes SQL over those tables and returns precise answers with real numbers from the model, not generated summaries.

Can I check an IFC model online without installing software?

Yes, for data checks. Upload the IFC and the agent queries the extracted tables so you can check property sets, classifications, fire ratings, quantities, and COBie fields in the browser. The IFC Model Checker page covers that validation pass in full. Rule-set validation of the Solibri or IDS kind is a different job and belongs in a dedicated checker.

What is the difference between viewing and checking an IFC model?

Viewing shows you the geometry and lets you click an element to read its properties. Checking asks whether the model is correct: whether required properties are populated, whether classifications and naming follow the project standard, and whether what the model says matches the drawings and specifications. Nomic covers the data and document side of checking. It does not run rule engines or repair models.

Is the IFC viewer free?

You can try Nomic for free. Sign up and upload an IFC to explore the 3D viewer and agent. Contact us for team and enterprise plans.
