Encode design intent, standards and decision logic directly into Siemens NX. CitiusKBE turns your engineering playbook into a living rule engine that builds, updates and validates 3D geometry automatically.
Both automate CAD, but they solve different problems. Rule-based geometry creation handles decisions your engineers make in their heads, the ones that templates alone cannot capture.
A well-designed rule captures inputs, conditions, geometry actions and validation. Here is a simplified view of how CitiusKBE structures rules inside Siemens NX.
CitiusKBE captures the full spectrum of engineering decisions your teams make every day, and embeds them into your Siemens NX environment.
Define how shapes, features and profiles are built based on inputs or product category.
Position holes, slots, ribs and bosses based on geometric references or design intent.
Enforce ISO, ASME, DIN, company and customer standards at the geometry level, not after the fact.
Auto-select materials and grades based on load, environment or application type.
Verify dimensions, clearances, wall thickness and interferences the moment geometry is built.
Flag designs that violate DFM constraints, bend radii or tool-access requirements.
A structured five-stage process that transforms tacit engineering knowledge into a production-ready automation plug-in for Siemens NX.
We interview senior engineers, review existing NX models and capture the undocumented design logic that drives your products.
Engineering decisions are formalized into structured rule sets with clear inputs, conditions, actions and validations.
Rules are implemented using NX Open APIs, journals and our KBE framework, packaged as a native NX toolbar plug-in.
The rule engine is tested against historical designs to confirm it reproduces correct geometry across edge cases.
Training, documentation and a rule-management framework ensure your team can evolve the logic as standards change.
CitiusKBE customers consistently report these outcomes within the first two quarters of deploying rule-based geometry automation.
Rule-based geometry creation delivers the biggest payoff in industries with strict standards, complex product families and repetitive design decisions.
| Industry | Typical Rule Applications | Value Impact |
|---|---|---|
| Aerospace | Bracket design, fastener patterns, stress-driven geometry, compliance checks | High |
| Automotive / BIW | Fixture layouts, clamp positioning, weld gun access, jig design rules | High |
| Heavy Engineering | Boiler tube layouts, pressure vessel nozzles, support structures | High |
| Industrial Machinery | Frame sizing, bolt patterns, cabinet layouts, mounting rules | Medium |
| Piping & Plant | Flange selection, pipe routing, support spacing, ASME compliance | High |
| Tool & Die | Die base rules, cavity layout, ejector pin positioning, shut-off logic | Medium |
Rule-based geometry creation is one layer of CitiusKBE's automation platform. Explore the connected capabilities that amplify its impact.
Straight answers to the most common questions from CAD managers, engineering leads and design teams evaluating rule-driven automation.
It is a CAD automation approach where engineering logic, design constraints and company standards are encoded as rules that automatically generate or modify 3D geometry. The rule engine decides how features are built, positioned and validated based on input conditions.
Parametric modeling drives geometry through numeric parameters and formulas. Rule-based geometry creation adds conditional logic, IF-THEN-ELSE decisions, validation checks and design rules, so the model adapts intelligently to different scenarios, not just different numbers.
Yes. CitiusKBE builds rule-based automation plug-ins for Siemens NX using NX Open APIs, journals and Knowledge-Based Engineering frameworks, fully integrated with Teamcenter.
Geometry creation rules, feature placement rules, standards compliance rules, material selection rules, validation rules and manufacturing feasibility rules can all be captured and automated.
Yes. CitiusKBE structures rules in a maintainable format with clear inputs, conditions and actions. Your team can update individual rules through a governance framework without rebuilding the entire automation.
You own it fully. The rule engine runs inside your NX environment as a plug-in, with full documentation and source ownership transferred to your team on project completion.
