# 1.0.0: the first stable release

Source: https://meptools.com/blog/platform-1-0-0

This is the first stable release. Six tools, two disciplines-worth of layout work and
four single-page calculators, all built to the same standard: show the engineer the
numbers, not just the answer.

## What ships today

- **Plant Room Studio** (MEP-01) — 2D/3D MEP plant-room layout, equipment placement,
  maintenance-access and clearance checks, with DXF/IFC exchange.
- **Ceiling Coordination Studio** (MEP-02) — plan, route, and auto-arrange above-ceiling
  MEP services.
- **Voltage Drop & Cable Size Checker** (ELC-01) — LV cable sizing and voltage-drop
  verification against BS 7671 data or custom impedance values.
- **Duct Pressure Drop Calculator** (MEC-01) — single-duct-run pressure drop via
  Darcy-Weisbach/Swamee-Jain and Huebscher equivalent diameter.
- **Water Pipe Pressure Drop & Pump Head Calculator** (PLB-01) — plumbing hydraulics,
  pump head, and pump power.

## Calculators that show their work

None of these tools are black boxes. Formulas, source tables, and assumptions are
shown alongside every result, so the number you copy into a report is one you can
defend in a design review.

## What's not here yet

The layout tools are entitlement-gated for premium exports (DXF/IFC), and the roadmap
has more coming — an MEP project-tracking hub chief among it. This release is the
foundation, not the finish line.
