From a Build Week Prototype to a Model-Driven Technical Project Workspace
Since the original OpenAI Build Week submission, XBE Transport Crate Engineering has continued to evolve while preserving the technical and safety boundaries of the submitted competition version.
Version distinction
- Submitted competition version: r8
- Current development and test status: post-submission development
- 757/757 tests passing
- 0 build errors
- 0 warnings
- Native Windows WPF application based on .NET 10 LTS
- Portable, self-contained x64 distribution with no pre-installed .NET runtime required
Improvements made after the initial submission are documented separately and are not presented retroactively as features of the original competition release.
From a crate model to an integrated transport system
The application no longer treats the packaging merely as an outer crate. Cargo, supports, understructure, fasteners and enclosure are modeled as one connected transport system.
Supported project types include:
- transport and export crates
- pallets and pallet bases
- transport and support frames
- modular understructures for workshop pre-assembly and on-site installation
The central principle remains:
The cargo is not adapted to a standardized crate. The packaging is developed around the real cargo, its support points, handling requirements and transport conditions.
Model-based engineering and documentation
The current development version includes:
- front, rear, side, top and bottom views
- rotatable isometric CAD visualization
- assembly-level and component-level exploded views
- assembly and component isolation
- construction-based parts, cutting and sawing lists
- component, position and fastener dimension chains
- physical contact surfaces and connection identities
- visible fastener paths and driving directions
- project-specific PDF and SVG documentation
- technical working drafts with an explicit approval status
The clearly marked PDF mode “WORKING DRAFT — not approved for execution” remains part of the system.
Understructure, cargo and load paths
Further developments include:
- primary and auxiliary supports
- force-free floating auxiliary supports
- cargo-specific mounting and bolting points
- spatial load-path classification
- perimeter and central load-bearing lines
- free spans and geometric load-transfer points
- scalable understructure and pallet grids
- modular floor sections with stable joint IDs
- assembly sequences and separate module parts lists
- calculated structural packaging weight
- total and design mass with a documented safety reserve
A geometrically complete connection still does not create an automatic load-capacity approval.
Materials and commercial calculation
The application now includes a shared materials system covering:
- materials and internal material numbers
- suppliers and supplier-specific articles
- explicitly confirmed technical equivalence
- immutable project-specific material and price snapshots
- configurable cutting allowance
- different materials, timber species, panel types and cross-sections
- documented exposure and protection conditions
The commercial module supports:
- target costing, work-in-progress costing and actual post-calculation
- material, fastener, labor, machine and external-service costs
- internal cost centers
- configurable surcharges and discounts
- markup or target-margin pricing
- multiple currencies
- project-fixed exchange-rate snapshots
- target-versus-actual comparison
- net invoice drafts
- structured preparation for accounting handover
A continuous project workspace
The application is evolving from an isolated calculator into a continuous project-based workspace:
CRM/customer → field survey → technical engineering → costing → quotation → proof/approval → manufacturing → post-calculation → project review → accounting
The foundation now includes:
- one stable central project ID
- user roles and permissions
- traceable change history
- version-based conflict protection
- technical and commercial approval records
- offline field-service drafts
- neutral CRM and accounting interfaces
- a server-ready licensing architecture without trivial client-side approval logic
A production central server, user authentication and specific CRM, accounting and licensing services are not yet part of the current local test build.
Transparent technical boundaries
The application keeps unresolved technical issues visible instead of inventing missing values.
These include:
- open fastener assignments
- unconfirmed physical connections
- unverified contact and support conditions
- unresolved cross-section verification
- missing material or product evidence
- unverified load distribution
- missing Finder bindings
- unapproved technical data packages
- manually acknowledged deviations
Technical data packages are checked for source provenance, version, integrity, applicability and formula dependencies. Invalid or cyclic formula chains are quarantined before any partial calculation can take place.
Known limitations
- Some drawing and PDF layouts still require visual refinement.
- Not every crate and pallet profile is fully implemented as a constructive model.
- The visible multi-user process interface is still under development.
- Production CRM, accounting and licensing servers are not yet connected.
- Further approved technical data packages and primary sources are required.
- The application does not issue general structural, regulatory, national or manufacturing approval.
How Codex and GPT-5.6 were used
XBE Transport Crate Engineering was created through close collaboration between practical industrial experience and AI-assisted software development.
Codex and GPT-5.6 were used to:
- transform decades of practical experience into stable data models
- iteratively convert technical requirements into executable software
- separate sources, engineering rules and safety boundaries
- connect CAD, calculation, documentation and project-process modules
- build and continuously expand the regression test suite
- keep assumptions visible instead of presenting unsupported results as verified facts
The project demonstrates how a technical prototype developed during OpenAI Build Week can evolve into a model-driven engineering workspace for industrial transport packaging.
