Walt Disney Imagineering relied on a business-critical AutoCAD toolkit to process ride engineering drawings and generate plottable layouts and bills of materials. The original system had been built primarily in AutoLISP and VBA by CAD users over time. What started as a collection of productivity tools had grown into a deeply embedded operational application — and it had become increasingly fragile and difficult to maintain. Modifying the existing codebase was projected to cost more than building a replacement from scratch.
What LegacyX Delivered
Rather than continue patching brittle legacy code, LegacyX re-architected the entire solution using AutoLISP, ObjectARX .NET, and Windows Presentation Foundation (WPF). The modern replacement was delivered in under one year, at lower cost than modifying the old system, with zero disruption to ongoing engineering workflows.
LegacyX also introduced source control and Azure DevOps-based application lifecycle management — bringing modern development discipline to a critical engineering toolset that had previously operated without it.
The replacement system remains in production use today.
