We don’t want you to miss any updates! Below you’ll find a recap of all APS blog posts published since our last recap — including major announcements, SDK updates, new code samples, and upcoming events.

Announcements

Autodesk API Support Winter Holiday Schedule 

If you rely on Autodesk API Support, make sure to note the winter holiday coverage window:

• Limited availability: from December 20, 2025 – January 4, 2026 (inclusive).
• Recommendation from the team: submit any outstanding questions by Friday, December 12, 2025, to help ensure a timely response before coverage is reduced. 

Keep this in mind for any planned changes or critical deployments around year-end.

 

APS Business Model Evolution

Autodesk Platform Services has launched a new business model for cloud APIs, built around two tiers—Free and Paid—to make usage more predictable and aligned with how your projects scale.

Key points you’ll want to be aware of:

• Two-tier model: A Free tier (with monthly caps for rated APIs like Automation, Model Derivative, Flow Graph, and Reality Capture) and a Paid tier with Flex (prepay) and Pay as You Go options.
• Required actions:
  • Enroll in a Free or Paid offering.
  • Migrate your apps to a developer hub so usage and billing are tracked properly.
• Timeline: You’ll have a grace window after rollout; if you haven’t enrolled and migrated by January 16, your API access will be suspended until you complete those steps.

Hear from Ben Cochran, VP of Developer Enablement, about this more flexible, future-ready way to access Autodesk APIs.

 

Lead the way – submit a class for Autodesk DevCon

Autodesk DevCon is returning in 2026, and the Call for Proposals (CFP) is now open.

Key details:

• Event dates: April 15–16, 2026 – Amsterdam, The Netherlands.
• Mix of 30-minute and 15-minute sessions across themes like AI, automation, ERP integrations, sustainability, and more.
• Proposal submission deadline: December 28, 2025.
• Up to 3 proposals per speaker; reviewers are looking for concrete, implementation-focused stories with clear takeaways.

If you have a strong APS success story—especially around AI, enterprise integrations, or digital transformation—this is your moment to get it on the DevCon stage.

 

Powering AI Innovation: Autodesk, AWS, and SAP Unite for APS Developer Accelerator in Munich

The Autodesk Platform Services (APS) Developer Accelerator program recently brought together experts from Autodesk, AWS, and SAP for a week of intense, hands-on AI innovation in Munich. The event, hosted at AWS’ office, was a powerful display of collaboration. Over the course of five days, 30 software developers across 15 projects collaborated to explore how AI, cloud, and platform services can fundamentally redefine what’s possible in Design and Make across the AECO and Manufacturing industries. Read the blog to learn about the tangible progress made on real-world challenges.

 

Update to Data Exchange SDK .NET (6.3.0) 

The Data Exchange .NET SDK has been updated to v6.3.0 (beta) with a focus on cleaner APIs and better performance:

Highlights:

• Improved type safety – color values are now integer-based (0–255) instead of floats, making them more intuitive and consistent with standard RGB usage.
• Streamlined geometry API – deprecations removed and a unified GeometryContainer replaces older patterns such as CurveSet.
• Performance wins – more efficient memory and geometry handling under the hood.

This release includes breaking changes, so plan your migration from 6.2.0 carefully using the migration guide and changelog linked in the post. 

 

ACC Cost API Update – New Contract Lifecycle Fields, Budget Code Enhancements, and Expense Edit Improvements 

The ACC Cost API has a set of incremental but powerful enhancements to make workflows more complete and auditable:

• New contract lifecycle timestamps like awardedAt, statusChangedAt, sentAt, approvedAt, and executedAt let you track contract progress more precisely across several Cost endpoints.
• Budget code fields (budgetCode and budgetFormattedCode) have been added to payment items so you can display human-friendly codes while still handling raw values in your systems.
• Editable mainContractId on expenses enables you to reassign or correct contract associations without brittle workarounds.

All of these changes are backward-compatible—no breaking changes, just more data and flexibility.

 

Call for feedback – Java SDK Beta 

APS has released a Beta Java SDK and is actively looking for developer feedback.

What’s included in this first round:

• Java packages for: Authentication, Data Management, Model Derivative, OSS, and Webhooks.
• Distribution via Maven Central for easy dependency management.

To participate, you can:

• Join the Autodesk Feedback Community via the link in the blog.
• Share feedback or feature requests with the team to help prioritize future services and languages.

 

Developer Tips, Tools & Code Samples

Enforce the Limit to property.name translations in Filter of the AEC Data Model Query

The AEC Data Model API is introducing an important update to how property.name based filters are processed. This change is designed to improve performance, stability, and predictability as datasets grow across hubs, projects, and models. See the official docs for details: Special Considerations for PropertyName Filters. 

 

Add Esri terrain to APS Viewer – with drawing tools 

Michael Beale takes APS Viewer to a new geospatial level by bringing Esri terrain directly into the Viewer and layering in AI-assisted tooling.

In this deep-dive, you’ll see how to:

• Use new Viewer extensions (Geo.Terrain and Geo.Tools) to overlay real-world Esri raster basemaps and elevation data.
• Decode Esri’s LERC elevation tiles and feed them into a terrain mesh.
• Snap models and drawn geometry to terrain, compute lat/long, and export GeoJSON polylines.

If you’re doing BIM + GIS mashups, geospatial dashboards, or digital twin visualizations, this post is packed with patterns and sample code you can adapt. 

 

Debugging Revit Plugins with Cursor: A Modern Developer Workflow 

João Martins, Michael Beale, and Zhong Wu show how to use Cursor + Revit for a much smoother debugging loop:

You’ll learn how to:

• Attach the debugger to a running Revit process instead of launching from scratch.
• Configure a VS Code / Cursor launch.json to attach to Revit.exe.
• Structure your project and .addin files so breakpoints and assemblies line up correctly.

This workflow saves time when iterating on Revit plugins and sets you up to leverage AI-assisted debugging with real-time logs and context. 

 

Debugging AutoCAD and Civil 3D Plugins with Cursor: A Modern Developer Workflow

The team extends the Cursor debugging pattern to AutoCAD and Civil 3D plug-ins:

This post walks through how to:

• Attach the debugger to acad.exe (and Civil 3D) using a pre-configured launch.json.
• NETLOAD your plug-in DLL and debug commands interactively.
• Tweak project settings and references to align with AutoCAD/Civil 3D 2025+ installations.

If you’re working across Revit, AutoCAD, and Civil 3D, the Revit + AutoCAD/Civil 3D Cursor posts together form a cohesive multi-product debugging playbook.

 

Revit Cloud Worksharing Migration Tool – Automation API 

This post presents a scalable migration workflow for Revit Cloud Worksharing (RCW) models from BIM 360 to ACC using the Revit Automation API.

What the sample solution does:

• Uses Revit Automation to download RCW models from BIM 360, open them as detached models, and re-publish them as new RCWs into ACC Docs.
• Wraps everything in a lightweight web app so non-developers can run batch migrations:
  • Configure activities/appbundles for Revit 2025/2026
  • Pick source and target folders
  • Launch parallel workitems and track status in real time

This is especially relevant if you’re planning large-scale BIM 360 → ACC migrations and need to reduce manual effort and risk.
