Where to download ObjectArx for 2026?

[Anton_Huizinga]

Today AutoCAD 2026 became available. The download page of ObjectARX does not provide downloads for the SDK yet. Is it moved? Or not available yet?

I can't even find the download for 2025, let alone 2026.

I finally found it, you have to follow the instructions here (so totally not obvious): https://forums.autodesk.com/t5/net/where-to-download-objectarx-for-2025/td-p/12667555

That works for 2026 as well
