Tests & Benchmarks

Test Results & Benchmarks

Standardized, reproducible benchmarks across open-source mechanical CAD tools. Each test follows a defined protocol with measurable outcomes. Architecture/BIM and electronics tools are listed for reference but not actively benchmarked.

Mechanical Tests (Active)

⚙️ Modeling Speed

  • Sketch → constrain → feature benchmark
  • Parametric regeneration time
  • Feature tree depth vs. performance

⚙️ Assembly Handling

  • Mate constraints & motion
  • BOM generation accuracy
  • Large assembly (100+ parts) performance

⚙️ CAM Workflow

  • Toolpath generation quality
  • G-code output validation
  • Post-processor compatibility

⚙️ Drawing Automation

  • TechDraw view creation speed
  • Dimension/annotation accuracy
  • Export fidelity (PDF, DXF, SVG)

⚙️ STEP/IGES Fidelity

  • Round-trip with commercial CAD
  • Geometry & topology preservation
  • Attribute/metadata retention

⚙️ Large Assembly Perf.

  • 100+ parts regeneration time
  • Memory usage under load
  • Graphical performance (FPS)

Reference Categories (Not Benchmarked)

These categories are documented for context but do not have active test protocols.

🏗️ BIM & Architecture

  • IFC round-trip fidelity
  • Clash detection workflows
  • Quantity takeoff from model
  • Drawing production (plans, sections)

🔌 Electronics & PCB

  • Schematic → PCB workflow
  • DRC/ERC rule coverage
  • Gerber/ODB++ manufacturing output
  • Simulation correlation

Methodology

  • Hardware baseline: AMD Ryzen 9 / 64 GB RAM / RTX 4080 (disclosed per test)
  • OS: Ubuntu 24.04 LTS (native) + Windows 11 (where needed)
  • Metrics: Time-to-result, file size, error count, feature completeness
  • Reproducibility: Test scripts + input files published with results
