NX AI Assistants & Chatbots

Some assistants answer. The good ones also act — and the trustworthy ones ask first.

NX AI chatbots are engineering assistants for the Siemens stack that come in two kinds: knowledge assistants answer questions about your standards, your parts and your processes with cited sources — and action assistants execute work in Siemens NX and Teamcenter: they model, check, author and file, through the same APIs your own tools use. Every action an assistant proposes is shown as a preview and applied only after the engineer confirms it.

The answering kind is mature — we run it in production for NX teams and regulated industries today. This page is mostly about the second kind, because that is where the routine hours actually sit: not in finding the answer, but in doing the fifty clicks that follow it.

Assistants that answer — grounded, cited, in production

Knowledge assistants answer from your own material — design guidelines, norms, past projects, CAD and Teamcenter data — and cite where every answer comes from. We build and run them today; they are documented on their own pages rather than repeated here:

Assistants that act — the six

This is the core of the family: assistants that execute operations, check at modeling time, and author geometry, annotations and documents — through the Vision4NX Connector, NXOpen and Teamcenter SOA. Each one is scoped tightly around a job your designers do every week, and each carries its own preview-and-confirm workflow:

How an assistant reaches into NX and Teamcenter

The action channel is the same for every assistant on this page, and it is deliberately boring: no screen scraping, no macros replaying clicks. The assistant speaks MCP to the Vision4NX Connector, which executes through NXOpen inside your NX session and through Teamcenter SOA on the PLM side — the same supported APIs your own automation tools use. It runs with your license, under your permissions, on-premises where your data must stay.

The tool layer underneath is a product in its own right: our Siemens NX MCP server page explains what an MCP server for NX actually is, what exists in 2026, and how we build a gated one on your own NXOpen libraries.

Working in Claude Code? Our Claude NX integration connects Claude Code to the live NX session: the same tool layer and gate, plus Claude Code’s own permission rules, hooks and per-tool approval.

Need more than one assistant? Our agentic CAD for Siemens NX page shows how research, building, checking and coding are split across separate agents that share the same gated tool layer.

Two pages zoom in on single capabilities of the same tool layer: AI CAD modeling in Siemens NX shows which modeling operations the AI runs as editable features, and NX MBD with AI shows which PMI an agent places on the 3D model today.

For drawings, AI 2D drawing creation in Siemens NX shows which drafting operations an agent runs in NX today and how every sheet is checked before an engineer releases it.

What these assistants deliberately don’t do

Nothing is applied without the engineer’s confirmation — no exceptions, no “auto mode”. The assistant proposes; the engineer signs. That is not a temporary safety wheel we plan to remove: in mechanical engineering, the person who releases the model carries the responsibility, and our architecture respects that. Every applied action is undo-safe and written to a log with who confirmed it and when.

They are also not the right tool for high-volume batch work. If the same rule-based job runs over five hundred parts every night, you don’t want a conversation — you want deterministic automation with fixed rules and a fixed result. That discipline has its own page: AI Workflow Automation for Siemens NX. The honest boundary: assistants for the ad-hoc and conversational, deterministic pipelines for the repetitive-at-scale — most customers end up with both, sharing the same NXOpen foundation.

And they don’t replace your CAD methodology. AI takes the routine — the clicks, the lookups, the boilerplate annotations. You keep the design.
