The Problem: Excel-Based Engineering Doesn't Scale

Many engineering teams rely on Excel spreadsheets for critical calculations. Over time, these spreadsheets become complex, interconnected, and difficult to maintain—containing decades of engineering knowledge locked in a fragile format.

The BottleNeck

Spreadsheets become fragile and opaque over time, creating critical risks.

  • Hidden Dependencies: Fragile logic that breaks easily when modified.
  • No Validation: High risk of inputs causing calculation errors.
  • No Audit Trail: No history of who calculated what or which rules were used.
  • Disconnected Data: Manual copy-paste to CAD creates transcription errors.

Smart Automation

  • Deterministic Engine Logic is rebuilt as a reliable engine that validates every input and handles branching complexity.
  • CAD-Linked Calculation Engine Calculation results directly drive CAD parameters, drawings, and reports — no copy-paste.
  • Audit-Ready Reports Automatically generate detailed PDF/Excel reports showing full derivation and pass/fail status.
Traceable. Validated. Integrated.

What You Can Expect

Validated Outputs

Zero calculation errors with built-in range checking and unit consistency.

Professional Reports

Audit-ready submittals generated instantly with full derivation history.

CAD Integration

Results drive geometry directly, eliminating manual data entry.

Audit Trails

Complete history of inputs, calculations, and outputs for compliance.

How It Works

From fragile spreadsheets to robust systems.

1. Logic Extraction

We decouple engineering rules from spreadsheet cells to create a clear, documented model, removing ambiguity and hidden dependencies.

2. Deterministic Engine

Logic is rebuilt as a standalone engine with input validation, ensuring outputs are always predictable (no manual overrides).

3. Report Generation

Automated generation of audit-ready technical documentation with full input parameter listing and derivation history.

4. CAD Integration

Validated results drive geometry directly, eliminating manual data entry and enabling automatic recalculation.

Why Not Just Fix the Spreadsheet?

Excel works for small, isolated calculations — but becomes a risk when engineering logic grows, calculations interconnect, and outputs affect manufacturing.

With Excel-Based Engineering

  • Logic is buried inside formulas that are hard to audit or validate
  • Manual edits introduce silent errors that go unnoticed
  • No enforced checks before calculations are reused or shared
  • Difficult to trace how a number was calculated weeks or months later

With Automated Engineering Systems

  • Engineering rules are explicit, versioned, and centrally managed
  • Every calculation is validated deterministically before output
  • Outputs stay consistent across reports, drawings, and revisions
  • Full traceability from inputs → formulas → final results
"When calculations drive real-world decisions, engineering logic must behave like software — not spreadsheets."
