SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill automates the process of identifying geometric conflicts and interferences within Building Information Models (BIM), ensuring design integrity and preventing costly construction issues.

Core Features & Use Cases

  • Clash Detection: Perform intersection, collision, or clearance checks between elements.
  • BCF/JSON Export: Generate reports in standard formats for issue tracking and analysis.
  • Smart Grouping: Automatically cluster related clashes to identify systemic problems.
  • Use Case: Detect if structural beams clash with HVAC ducts in a multi-disciplinary BIM model, export the results as a BCF file for coordination meetings, and then group similar clashes to prioritize resolution efforts.

Quick Start

Use the bonsai-impl-clash skill to detect intersection clashes between structural and MEP elements in the provided IFC files and save the results to a JSON file.

Frequently Asked Questions about bonsai-impl-clash

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run clash detection on IFC BIM models for structural and MEP coordination?▼

Run clash detection in Bonsai using IfcClash by defining clash sets with element groups and filters, then executing intersection tests to identify geometric conflicts between structural and MEP elements.

Can I export BIM clash detection results for issue tracking?▼

Yes, you can export clash detection results to BCF or JSON formats, enabling seamless issue tracking and analysis during multi-disciplinary coordination meetings.

How does smart grouping work for BIM clash detection results?▼

Smart grouping automatically clusters related geometric clashes together, helping teams identify systemic interference problems and prioritize resolution efforts more effectively across the BIM model.

Do I need IfcOpenShell to perform interference checks in Bonsai?▼

Yes, performing interference checks and collision analysis requires having the Bonsai addon installed alongside IfcOpenShell v0.8.x to execute spatial coordination workflows.

What types of spatial coordination checks can I perform on BIM elements?▼

You can perform intersection, collision, and clearance checks between defined element groups, allowing for comprehensive spatial coordination and interference analysis within IFC models.

Why are my clash sets not returning expected interference results in Bonsai?▼

Incorrect clash detection results often occur when element groups and filters are improperly defined, requiring you to verify your clash set configurations before running intersection tests.
