- **Technical Dimensioning & Measurement:** Interactive ruler tool allowing users to click two points on a blueprint to draw technical dimension lines with exact distances in millimeters and pixels.
- **Themes:** AutoCAD Dark Mode, Engineering Cyan Blueprint Mode, and Print Paper Mode.
- **Image & PDF Blueprints:** Zoom, pan, and dimension measurement tools also work on scanned blueprints and raster images.

### Module D: Electrical Engineering Suite (https://ztzsoftware.com/herramientas?categoria=engineering)
- **Voltage Drop Calculator:** Evaluates single-phase (220V) and three-phase (380V) circuits for Copper ($\rho = 0.0175\ \Omega\cdot\text{mm}^2/\text{m}$) and Aluminum ($\rho = 0.028\ \Omega\cdot\text{mm}^2/\text{m}$). Enforces IEC/NEC standards ($\le 3\%$ limit), computes thermal power losses ($I^2R$), and automatically recommends minimum cable gauge (AWG and $mm^2$).
- **Universal Power Converter:** Instant multi-variable conversion between Kilowatts (kW), Horsepower (HP / CV), Kilovolt-Amperes (kVA), Watts (W), and BTU/h (HVAC thermal load), plus estimated line currents at 220V and 380V.
- **Electrical Panel & Breaker Sizing:** Computes nominal currents, selects standardized thermal-magnetic circuit breakers (Curves C and D), residual current devices (RCDs 30mA), and main feeder sizing with simultaneity factors ($F_s$). Exports complete load schedules directly to Microsoft Excel (.xlsx).

### Module E: Text & List to Excel Converter (https://ztzsoftware.com/herramientas?categoria=data)
- Converts unformatted text, lists of materials, quotations, or web tables into clean spreadsheets.
- Auto-detects delimiters (tabs, commas, semicolons, pipes).
- Generates native Microsoft Excel (.xlsx) and UTF-8 BOM CSV files.

### Module F: Audio & Video Suite (https://ztzsoftware.com/herramientas?categoria=audio)
- Extracts audio tracks from MP4/WebM videos into MP3 or lossless WAV.
- Compresses audio with bitrate adjustments (64 to 320 kbps) and mono downmixing.
- Trims audio clips with second-level precision.
