BIWFix Pro delivers intelligent rule-based automation for Body in White fixture design on Siemens NX. Speed up fixture development cycles, eliminate costly rework, and produce manufacturing-ready outputs from the first design pass.
Body in White (BIW) fixtures are the precision engineering backbone of every automotive body assembly line. They locate, clamp, and support sheet metal panels to exact tolerances during welding, hemming, and inspection — and they must be right the first time.
Traditional BIW fixture design is a knowledge-intensive, manual process. Engineers spend significant time positioning clamps, defining locator points, validating clearances, and producing manufacturing documentation — all of which is repetitive, error-prone, and heavily reliant on specialist expertise.
CitiusKBE's BIWFix Pro changes this dynamic entirely. It encodes proven fixture design rules into an intelligent automation engine that runs natively inside Siemens NX, turning days of manual fixture design work into hours of guided, validated output.
Talk to a BIW SpecialistAutomotive OEMs and tier-1 suppliers face these same fixture design bottlenecks across every new vehicle program. BIWFix Pro is engineered to resolve all three.
Manual clamp positioning, clearance validation, and documentation cycles stretch BIW fixture development across weeks. In competitive automotive programs, that timeline directly impacts SOP dates and launch readiness.
Without inline validation, fixture design rule violations are discovered during physical tryout or manufacturing review — at the point where correction is most expensive and time-consuming.
BIW fixture design quality is directly tied to the availability of specialist engineers. When that expertise is not available or leaves the organization, consistency and quality drop immediately across the program.
BIWFix Pro brings rule-based intelligence directly into Siemens NX. Fixture engineers work within their familiar CAD environment while the automation engine handles clamp placement logic, locator positioning, clearance validation, and manufacturing output generation automatically.
The tool encodes your organization's fixture design expertise — OEM-specific rules, clearance standards, clamp type libraries, and manufacturing constraints — into a reusable, scalable knowledge base that works consistently for every engineer on the team, regardless of experience level.
The result is faster fixture development with fewer iterations, first-time-right manufacturing outputs, and a fixture design process that scales without depending on individual specialists.

Each capability directly addresses a real bottleneck in the BIW fixture design and manufacturing engineering workflow.
BIWFix Pro automatically positions clamps and locators based on panel geometry and encoded fixture design rules, eliminating manual positioning decisions and placement errors.
Design rule checks run continuously during fixture creation, flagging clearance violations, standard deviations, and non-conformances before any manufacturing documentation is produced.
Automated quality checks validate fixture geometry, pin locations, clamp accessibility, and weld gun clearances against OEM specifications and manufacturing requirements.
BIWFix Pro generates complete manufacturing-ready fixture drawings, assembly specifications, and documentation in one automated step directly from the validated NX model.
Structured Bills of Materials and inspection reports are generated automatically and linked to model attributes, removing manual extraction from every fixture delivery milestone.
Customer-specific fixture standards, clamp libraries, material constraints, and design rules are encoded into the toolkit, making specialist knowledge available to every team member.
The entire BIW fixture design workflow runs inside Siemens NX. No switching platforms, no data translation, no workflow disruption.
Open your Body in White assembly in Siemens NX and launch the BIWFix Pro interface.
Select fixture type, panel geometry, and assembly requirements using guided parameter inputs.
BIWFix Pro automatically places clamps, locators, and supports based on your encoded design rules.
The rule engine validates all placements and flags any clearance or standard violations instantly.
Generate manufacturing-ready drawings, BOM, and QC reports in one automated export step.
BIW fixture design automation delivers measurable gains from the first vehicle program it is deployed on. The impact is visible in fixture delivery timelines, rework costs, and manufacturing launch readiness.
Program managers gain predictable fixture delivery because BIWFix Pro removes the variables that historically caused overruns: late-stage design rule violations, manual documentation effort, and dependency on individual specialist availability.
