In the modern product landscape, mechanical and electrical design teams working in silos aren’t just inefficient, they’re a serious business liability.

You know the big problems, missed deadlines, rework, scope creep. But what about the smaller details?

The overlooked terminal that clashes with a mounting bracket, the wire that exceeds its bend radius due to a tight enclosure, the last-minute prototype that fails because the mating electrical connector was off by 2mm.

These aren’t theoretical, they’re the exact kinds of problems that cost companies huge amounts per project.

According to a McKinsey report, transitioning from traditional, discipline-focused models to more digitally integrated and cross-functional operating models has resulted in time and cost savings of anywhere between 30% and 50%, along with significant improvements in quality and “first-time-right” metrics.

That’s not just a workflow issue; that’s a serious business problem.

I’ve worked on both sides of the aisle, from P&IDs built in outdated 2D tools to multi‑discipline electromechanical workflows that run on real-time design logic.

In this article, I’ll share how strategic use of integrated workflows, not just tools, has driven efficiency, cut costs, and accelerated time to market for customers facing real-world disconnects between electrical and mechanical design.

Insight #1: Miscommunication = Money Lost

One of the biggest pain points I encounter regularly is the assumption that mechanical and electrical teams can operate independently without consequence. This isn’t just a technical misstep, it’s a strategic failure.

There was a project where the client, operating in the industrial automation sector, relied on generic, free electrical software to handle schematics. The problem? Their symbols were inconsistent, wiring was unclear and most notably, BOMs and BOQs were manually compiled in Excel.

This led to inconsistencies with every project. One version of the BOM would be used by the design team, another by procurement, and a third by production. Their mechanical team would often wait for finalised electrical designs, which frequently came late or incomplete due to constant revisions.

Procurement teams were constantly having to reorder components at the last minute, adjust for missing part numbers, or return items that didn’t match the mechanical requirements. Because the electrical BOM lacked real-time integration with the mechanical design, components were often specified without confirming size, mounting, or compatibility.

The mechanical team, meanwhile, was left waiting. They’d begin assembling enclosures or panels only to find that the connectors didn’t align with cut-outs, or that cable types were incorrect. Every misstep forced them to halt work while procurement scrambled to find replacements – sometimes with extended lead times and higher costs. The lack of standardisation created confusion downstream, leading to poor system representation and an estimated R50,000 – R100,000 in losses per project. This loss only scaled as the project did.

Their electrical workflow was restructured using SOLIDWORKS Electrical, where I established consistent symbol libraries, automated BOMs, and integrated port validation. This allowed the mechanical team to access up-to-date designs in real-time, significantly improving coordination and reducing delays across departments.

This resulted in accurate data representation which led to significantly faster project turnarounds, improved communication between departments, and reduced costs by over 30% in some cases.

Insight #2: Outdated 2D Workflows Are Holding Your Projects Back

Many companies still rely on traditional 2D CAD to develop electrical schematics and P&IDs, often because it’s what they’ve always used, or because it’s perceived as “good enough”. But in today’s fast-paced product development cycles, good enough isn’t cutting it anymore.

I worked with a company in the water treatment sector where their electrical and mechanical designs were completely disconnected. Electrical engineers produced 2D schematics using standalone tools, while the mechanical team worked in 3D.

Every design iteration required manual cross-referencing, which opened the door to errors, misalignments, and late-stage surprises, especially when enclosure constraints, wire routing, or connector placement had to be validated in real physical builds.

This resulted in frequent rework, prolonged testing cycles, and mounting frustration across teams. Their reactive workflow made it nearly impossible to keep pace with project deadlines or scale the design efficiently.

I implemented SOLIDWORKS Electrical 2D & 3D, creating a fully integrated environment where electrical schematics were synchronised with 3D mechanical models.

• Electrical teams could route cables virtually, ensuring feasibility within the actual enclosure design.
• Real-time visibility helped both disciplines catch spatial conflicts, verify wire lengths, and apply correct terminal assignments based on physical layout and connection logic.
• Design updates became visible across the board, making version control and collaboration seamless.

This transformation didn’t just improve accuracy, it fundamentally changed the way they approached product development. They cut rework by 40%, accelerated prototyping, and prevented the costly domino effect that begins when one late discovery triggers a chain of last-minute corrections. 2D tools may draw the lines, but they don’t connect the dots. For businesses looking to innovate faster and smarter, it’s clear that 2D-only workflows are no longer viable.

Insight #3: 3D Models Must Reflect Real Electrical Constraints to Be Reliable

A client in the automotive manufacturing sector ran into unexpected issues during final assembly. A power cable intended for the engine bay had to make a sharp bend around a bracket, violating its minimum bend radius.

On top of that, signal cables were routed too close to high-current lines, causing EMI (electromagnetic interference) during testing. None of these problems were visible in the mechanical CAD or electrical schematic alone—they only became apparent on the shop floor.

These issues weren’t caught in 2D schematics or standalone 3D mechanical designs—they only surfaced during physical assembly and testing, when the cost of fixing them had already multiplied.

After SOLIDWORKS Electrical 3D was implemented, integrating the electrical schematics directly into the 3D model. This enabled virtual routing, spatial validation, and wire segregation planning.

• Signal and power wiring were properly separated to prevent interference and meet compliance standards.
• Accurate wire lengths as well as minimum bend radius constraints were captured up front, eliminating surprises during harness fabrication.

By transforming their 3D model into a fully aware, electromechanical workspace, the team gained the ability to design confidently for real-world constraints—reducing rework, improving vehicle reliability, and tightening production schedules.

Conclusion: It’s Not Just Integration. It’s Risk Prevention.

People often ask me if SOLIDWORKS Electrical is “worth the investment.” My answer is always the same: If your electrical and mechanical teams ever meet during production instead of design – you’ve already paid for the software upgrade.

The 1% mistakes are often the ones that snowball. The symbol mismatch, the incorrect terminal label, the forgotten clearance check – all tiny alone, but together? They become the bottleneck between design and delivery.

With SOLIDWORKS Electrical, we’re not just fixing drawings. We’re embedding design intelligence into the very backbone of product development. Fewer assumptions, more precision. Less rework, more reliability.

Key Takeaways:

• The biggest risks in design often come from the smallest details.
• Change management must be proactive, not reactive – traceable, not optional.
• The mechanical 3D model must reflect real-world electrical data to be trustworthy.
• Integration is no longer a feature—it’s the foundation of scalable, profitable product development.

Stop relying on disconnected, manual processes that belong in the past. Your competition isn’t waiting, and neither should you.
