Custom Autodesk Plugin Development: Packaged, Deployable, Sellable

Professional plugins for AutoCAD, Inventor, Revit and other Autodesk products, built as real software products: multi-version support, licensing, installers, automatic updates and Autodesk App Store publishing.

From internal tool to software product

Some tools stay inside one team. Others need to be deployed across many offices, supported for years across several Autodesk versions, or sold to customers. These plugins need more than working code: shared cores that serve multiple products, clean installers, licence management, update channels, documentation and a support process.

ENGIMANDI develops Autodesk plugins with a product mindset. We structure code so one core serves several Autodesk products and versions, package plugins as Autodesk bundles or MSI installers, add licensing and activation, set up automatic updates and telemetry where appropriate, and prepare everything for Autodesk App Store submission. Software vendors and equipment manufacturers use this service to give their customers Autodesk tools under their own brand.

FAQ

Plugin questions

How is this different from add-in development?

Add-in work focuses on in-product tools for your team. Plugin product work adds packaging, licensing, multi-version support and distribution for wider or commercial use.

Can we sell a plugin you build?

Yes. You own the code and can sell it directly or through the Autodesk App Store.

How do you handle new Autodesk releases?

We test on Autodesk beta and new releases and ship updated builds, usually as part of a maintenance plan.

Can one plugin work in AutoCAD and its verticals?

Yes. A single plugin can support AutoCAD, Civil 3D, Mechanical, Electrical and other toolsets.

Do you protect the code?

Yes. We use obfuscation, native code or licensing checks where appropriate.
