Open in browser, install offline
Open StructArk in any modern browser, then install it as a PWA when you need offline access. No desktop setup and no license server.
Linked BIM + analytical model
Keep physical BIM geometry and analytical members in sync so model updates stay coordinated through iteration.
Deterministic linear FEA
Run deterministic linear FEA directly in the browser for frames, members, slabs, and walls.
How engineers use StructArk
Model, analyze, report, and hand off in one flow.
StructArk follows a practical structural workflow from live model updates, to deterministic analysis, to reports and export-ready files.
02
Analyze and check
Run deterministic linear FEA in the browser, review the results quickly, and iterate before handoff.
03
Report and export
Generate structured PDF calculation reports and export IFC, DXF, and PDF for downstream tools.
04
Save local and review in AR
Save projects as portable .frag files on your device and review the model in browser-native WebXR AR when useful.
What makes StructArk different
Structural modeling and analysis, built for practical browser workflows.
Use one browser-native workspace for linked models, deterministic linear FEA, structured reports, and clean handoff exports.
Linked BIM + analytical model
Keep physical geometry and analytical members synchronized as the model evolves.
Linear FEA in the browser
Run deterministic structural analysis without desktop software for members, frames, slabs, and walls.
Model-aware engineering assistant
Edit the live model and apply project-specific engineering logic from uploaded formulas and tables.
PDF reports
Generate structured engineering reports with assumptions, calculations, results, and model images.
IFC import & IFC / DXF / PDF export
Bring in IFC geometry and hand off clean IFC, DXF, and PDF files downstream.
Offline / PWA
Install from the browser and continue working without network access after setup.
Local-first .frag files
Keep projects private and portable on your device with file-based project storage.
Browser-native AR
Review your structure in WebXR directly from the browser when on-site context helps.
Engineering assistant
An engineering assistant for your actual model.
Upload project-specific formulas, tables, section libraries, and local engineering rules. StructArk's model-aware engineering assistant can apply that logic to the live model, assist calculations, explain assumptions, and generate structured reports under engineer supervision.
Model-aware
The assistant understands members, nodes, loads, sections, materials, supports, and load cases in the active structural model.
Project-specific engineering logic
Upload formulas, equations, material tables, section libraries, and seismic parameters. The assistant applies them to the current project.
Explain and iterate
Review failures, inspect assumptions, suggest alternatives, and test framing changes quickly.
Structured reports
Generate PDF calculation packages with assumptions, equations, results, model images, and project notes.
Reusable project setups
Transfer assistant setup across projects with CSV templates to reuse project logic faster.
Assistant avatar
A model-native engineering assistant designed for structural workflows, project-specific rules, and explainable decisions.
Built to support engineering workflows
Use the assistant for repetitive model edits, project-specific calculations, and report generation while the engineer remains in control of project decisions.
