Problem
A production WPF plugin built for MicroStation needed to run on AutoCAD without rebuilding the UI or business logic. The team needed platform independence for potential future CAD host targets.
CAD Guardian LLC · Proof detail
Platform-Agnostic Plugin Migration
Bounded-scope execution that migrated a CAD plugin across platforms while preserving independence for future hosts.
TL;DR
The engagement succeeded because it treated the migration as an abstraction boundary problem. Core WPF application logic was decoupled from CAD host APIs, enabling a single codebase to target multiple platforms.

Buyer answer
What this proof shows.
This CAD Guardian LLC case study shows cad plugin migration for a sanitized buyer segment: energy & electric substations company. The public record keeps private names offline while exposing the problem, system boundary, execution pattern, and buyer-safe outcome.
System boundary
Core WPF application / Host abstraction layer / Platform adapters
Public proof
A single WPF codebase that targets both MicroStation and AutoCAD through host adapters.
Buyer use
Use this proof when the same class of Autodesk, MicroStation, SolidWorks, CAD, .NET, workflow, or engineering systems risk needs a bounded first phase.
Proof command file
The public record shows the pattern, not the client.
This route is designed for buyers who need enough proof to trust the engagement model before a private discovery call.

Delivery moves
How the work moved from risk to handoff.
A production WPF plugin built for MicroStation needed to run on AutoCAD without rebuilding the UI or business logic. The team needed platform independence for potential future CAD host targets.
Audit existing MicroStation-specific API calls and isolate them from core WPF application logic.
Introduce a host abstraction layer that decouples the plugin from any single CAD platform.
Implement AutoCAD host adapter and validate feature parity across both platforms.
Outcome ledger
Approved public results.
A single WPF codebase that targets both MicroStation and AutoCAD through host adapters.
A clean abstraction boundary that makes future platform expansion straightforward.
Delivered within the 60-hour scope with zero scope creep.
Sanitization note
What stays private.
This proof is derived from a private project and private business records. Public language is limited to approved patterns, neutral client labels, and redaction-safe outcomes.
No client names, stakeholder names, internal codes, filenames, drawing numbers, part numbers, proprietary dimensions, source files, or branded screenshots are exposed here.
