Turn engineering logic into live 3D models. CitiusKBE delivers rule-based parametric automation built exclusively for Siemens NX, so design teams generate error-free variants in minutes instead of days.
Parametric model generation is a CAD automation method where 3D geometry is built and updated through controlled input parameters and engineering rules. Change a dimension, material grade or configuration value and the model, its features and its drawings rebuild themselves automatically, without manual rework.
Our parametric automation pipeline turns your existing design logic into repeatable, validated CAD output, integrated directly inside your Siemens NX environment.
We study your existing NX models, drawings and standards to document parameters, relationships and engineering rules that drive product design.
Using NX Open APIs, journals and KBE frameworks, we translate that logic into a plug-in that lives inside your NX toolbar.
Engineers enter inputs through a simple UI. The system generates models, drawings and BOMs, then auto-validates against standards using our QC-Mate NX Suite.
Where T_manual is hours spent per variant manually, T_auto is hours after automation, and Variants is the annual number of configurations produced. For most CitiusKBE customers, parametric automation breaks even within 3 to 6 months.
A side-by-side view of what changes when engineering teams move from manual rebuilds to rule-driven, parametric generation inside Siemens NX.
| Parameter | Manual CAD Modeling | CitiusKBE Parametric Automation |
|---|---|---|
| Time per new variant | 4 to 12 hours | 2 to 10 minutes |
| Design error rate | High (manual rework loops) | Near-zero (rule-validated) |
| Standards enforcement | Inconsistent across teams | Automatic via StandardMate NX |
| Knowledge retention | Lives in senior engineers' heads | Captured in rule engine |
| Drawing regeneration | Manual rework needed | Auto-updated with model |
| Scalability | Limited by headcount | Unlimited variants |
Parametric model generation scales across any industry that designs configurable or engineered-to-order products. These are the sectors where CitiusKBE delivers the biggest impact.

Time spent per 100 variants, based on aggregated CitiusKBE customer data across NX CAD deployments.
When parametric automation is combined with KBE rules, validation and auto-drafting, design teams recover hundreds of engineering hours every quarter. This translates to faster quotes, more won deals and significantly higher margins on engineered-to-order product lines.
Parametric model generation works best when paired with validation, drafting and data automation. Explore the connected services in the CitiusKBE toolkit.
Common questions from engineering managers, CAD administrators and design leads evaluating parametric automation for Siemens NX.
It is a CAD automation method where 3D geometry is driven by engineering parameters and rules. Changing an input value automatically rebuilds the model, its features and downstream drawings, removing manual rework and eliminating inconsistencies between variants.
Templates only store a starting geometry. Parametric automation adds engineering rules, validation logic, configuration handling and drawing updates. Combined with Knowledge-Based Engineering, it captures decision logic, not just shapes.
CitiusKBE specializes in Siemens NX plug-ins and automation toolkits, with seamless integration into Teamcenter and other PLM environments.
Scoping and discovery usually takes 2 to 4 weeks. Development ranges from 6 to 16 weeks based on complexity, number of variants and integration needs. Most clients see positive ROI within 3 to 6 months of go-live.
No. CitiusKBE toolkits run on top of your existing Siemens NX licenses as plug-ins. No additional CAD seats or infrastructure are required.
Parametric modeling is a subset of Knowledge-Based Engineering. KBE adds engineering rules, design intent and validation logic on top of parametric relationships to automate entire product families, not just single models.
