Executive Summary

Preparing files for a metal 3d printing service requires strict adherence to geometric tolerances and design specifications. HappyCAD automates the review of technical drawings, DXF files, and BIM models to catch compliance issues early. By extracting critical data directly in the browser, engineering teams can transition from design to production with confidence.

  • Automate CAD drawing audits to prevent costly manufacturing errors.
  • Extract and visualize critical engineering data without manual scripting.
  • Ensure compliance for complex parts before sending them to production.

Medical Device PCB Risk AssessmentOpen interactive dashboard

1.Medical Device PCB Risk Assessment

PCB Engineering Team · 2026

Engineering teams preparing components for a selective laser sintering service must rigorously evaluate potential failure modes during the design phase. This HappyCAD dashboard visualizes a Design FMEA risk profile for a medical-device PCB team, specifically highlighting the RPN trap where high-severity items are masked by low overall scores. By utilizing text summaries, a bar chart, and a scatter plot, engineers can identify critical design flaws before utilizing a powder 3d printer for component housing.

What it shows:

Visualizing DFMEA risk profiles prevents high-severity design flaws from being overlooked during the prototyping phase.

Automated CAD Compliance ReviewOpen interactive dashboard

2.Automated CAD Compliance Review

Senior Engineering Design Reviewer · 2026

Transitioning from design to 3d printing metal parts requires strict documentation, which this dashboard supports by generating a compliance error analysis for a senior engineering design reviewer. The interface features KPI cards summarizing a batch of three reviewed drawings, revealing a 66.7 percent non-compliant rate and a 100 percent title mismatch rate across all records. By automatically extracting these metrics from raw files, HappyCAD eliminates manual Python scripting and provides an immediate view of systemic documentation gaps for rapid prototyping 3d printing workflows.

What it shows:

Automating compliance checks eliminates manual data engineering and immediately highlights recurring drawing failure modes.

BIM Functional Area ExtractionOpen interactive dashboard

3.BIM Functional Area Extraction

BIM Analyst · 2026

This HappyCAD dashboard displays the results of an automated functional area analysis, solving the challenge of extracting nested space metrics from an IFC building model. The interface translates extracted NetPlannedArea values into a clear space-program review, highlighting a net-to-gross efficiency of 95.5 percent alongside a horizontal bar chart comparing the 18.50 square meter Living Room to the 6.08 square meter Entry Hall. A donut chart visualizes the functional split, showing usable space accounting for 75.3 percent of the total net area, while a treemap proportionally maps these allocations.

What it shows:

Automating the extraction of nested IFC property values generates a verified space register without manual spot-checks.
