Equation-Driven Sheet Metal Chassis for Acoustic Recording Studios.

Parametric, equation-driven design that cut studio resize iterations from ~1 week to ~10 minutes.

Client snapshot

• Industry: Pro audio / acoustic engineering.
• Region: Europe.
• Engagement: Lead designer for studio chassis system, working with an international engineering team.
• Confidentiality: Under NDA. Client name and specific studio identifiers omitted.

The problem

The client needed a complete sheet metal chassis system for acoustic recording studios. Studio sizes vary from project to project, with each variant containing several thousand individual sheet metal components. Manually re-modeling the chassis for each new studio configuration was costing roughly a week of engineering time per resize, and managing the manufacturing drawings, tolerance stack-ups, and assembly references manually was driving avoidable errors on the shop floor.

Constraints

• Studio dimensions vary significantly per project — each new build was effectively a custom assembly
• SolidWorks performance under load with multi-thousand-component assemblies
• Acoustic performance requirements demanding precise sheet metal fits with no leakage paths
• International team collaboration across time zones
• Strict timeline aligned to the client’s installation schedule

My approach

• Acted as lead designer for the full studio chassis system
• Top-down assembly methodology to keep SolidWorks performance stable at scale
• Equation-driven parametric design so studio dimensions, panel counts, and bracket positions could be regenerated from a small set of master parameters rather than re-modeled manually
• GD&T-driven workflows (ASME Y14.5) on every drawing package, with consistent datum schemes across the assembly to reduce ambiguity for the fabricators
• Automation-supported drawing generation to keep the manufacturing package in sync with the design as parameters changed
• Used GD&T discipline and automation in tandem to reduce assembly errors compared to a manual workflow on a project of this scale

What I delivered

• Native SolidWorks parametric chassis assembly with equation-driven configuration logic
• DFM-ready flat patterns and DXF laser-cut files for each studio variant
• Bend tables, BOMs, and ASME Y14.5 GD&T manufacturing drawings
• STEP / IGES exports for client and fabricator handoff
• Documentation of the parameter system so the client’s internal team could regenerate new studio sizes without re-engaging me for every iteration

Outcome

• Studio resize iterations reduced from ~1 week to ~10 minutes. Once the parametric system was in place, generating a new studio size was a parameter update rather than a re-model.
• Significantly reduced assembly errors on the shop floor through GD&T-driven drawings and automation-supported drawing generation, compared to a manual workflow on an assembly of this size.
• Stable SolidWorks performance maintained throughout the project despite multi-thousand-component assembly size.
• Documented design system allowed the client’s internal team to regenerate new variants independently.
