AutoCAD Plugin Development
AutoCAD plugins built for production.
AutoCAD .NET API development with host-abstraction architecture so a single codebase can target AutoCAD, MicroStation, or future CAD hosts. Bounded scope, zero scope creep delivery.
TL;DR
AutoCAD .NET API plugin development with host-abstraction architecture, delivered in bounded scopes (60-hour engagements typical). Built so a single codebase targets multiple CAD hosts.
Outcomes
60 hours
Bounded scope on past cross-platform plugin migration
Zero
Scope-creep incidents on bounded plugin engagements
Single
Codebase targeting multiple CAD hosts via adapter pattern
What you receive
- AutoCAD .NET add-in with host-abstraction layer (so you can target other CAD hosts later without a rewrite).
- Deployment package (MSI/MSIX/ClickOnce) with versioning and CI/CD-friendly build.
- Test harness covering host adapter behavior so future CAD upgrades have a verification surface.
- Architecture documentation describing the seams, ready for an internal handoff or follow-on contract.
Best fit
- AutoCAD .NET plugins that need to ship to production with deployment, versioning, and upgrade support.
- Teams maintaining a CAD plugin across multiple hosts (AutoCAD, MicroStation, etc.) who want a single codebase.
- Buyers who want a bounded-scope engagement with clear acceptance criteria, not open-ended T&M.
- Engineering teams building configurators, drawing automation, or CAD-to-data pipelines on AutoCAD.
Not a fit
- AutoLISP-only engagements with no .NET surface.
- Pure end-user AutoCAD support or template authoring.

Glossary
Terms buyers usually ask about
- AutoCAD .NET API
- The managed programming interface for building production AutoCAD commands, plugins, automation, and integrations in C# or other .NET languages.
- Host abstraction layer
- A boundary that keeps shared plugin behavior separate from AutoCAD, MicroStation, Inventor, or other CAD-host-specific APIs.
- CAD-hosted plugin
- A desktop extension that runs inside a CAD application and uses that host API for drawing access, commands, selection, and UI integration.
- Adapter pattern
- A design pattern that translates each CAD host API into a shared contract so one core codebase can support multiple platforms.
FAQ
AutoCAD Plugin Development questions
Yes. Cross-platform plugin migration is a delivered pattern — see the platform-agnostic plugin migration case study. Typical engagements bound the work to 60 hours with explicit acceptance criteria.
Sometimes, when it intersects with a .NET plugin. Pure AutoLISP-only engagements are usually a better fit for a different specialist.
Deployment via MSI, MSIX, or ClickOnce depending on environment. CI/CD pipelines build per-version artifacts so AutoCAD 2024 and 2025 users can each receive a compatible build.
API surfaces are abstracted from business logic, and the build pipeline targets each supported AutoCAD version. Upgrade rehearsal runs in a separate environment before production rollout.
Yes when the shared logic dominates host-specific logic. The pattern is a host abstraction layer with one adapter per CAD platform. The cross-platform plugin migration case study delivered exactly this.
