  "summary": "Siemens NX is automatable today through NX Open. Siemens publishes a current NXOpen .NET Reference Guide for release 2512, including assembly-positioning and other model classes generated from official C# sources. That is a first-party in-process API for a licensed NX or Designcenter install. In June 2026 Siemens renamed Designcenter NX to Designcenter for both on-premises and Designcenter X SaaS; this record keeps the permanent siemens-nx slug for that CAD/CAM identity. The product page also describes browser-based Designcenter X Essentials alongside desktop seats. Current programmer guides and some language references sit behind Support Center, so public HTML is thinner than Autodesk or SOLIDWORKS pages. No first-party MCP, named low-code connector, CLI, or computer-use result was established.\n"
