AMetric Toolbox
A single application bundling calculation and verification tools for structural engineering, designed for everyday work in professional studios and engineering firms.
Each tool is self-contained but shares the same interface and the same usage logic.
A single installer brings every tool to your computer: four of them stay free forever, while the paid modules — Seismic Isolator HDRB and General RC sections — can be tried for 30 days with no feature limitations.
Variable loads NTC 2018, Seismic spectra NTC 2018, and General RC sections connect to an AI assistant such as Claude or ChatGPT through MCP: you ask for a calculation and the Toolbox runs it on your PC.
Variable loads NTC 2018
Snow, wind and thermal actions to NTC 2018Pick the municipality and the app derives zone and altitude, then develops snow, wind and temperature step by step, every NTC 2018 formula already substituted.

Seismic spectra NTC 2018
Elastic and design response spectraFrom the point on the map to the parameters interpolated from the grid: elastic and design spectra for every limit state, with a draggable point on each plot.

Rectangular RC sections
Rectangular reinforced-concrete section checksULS, shear and serviceability checks to NTC 2018 and the 2019 Circular: every check with its own domain plot and the N-M action points overlaid.

Activity Coordination
Shared schedule for the practice's activitiesA Gantt chart for the practice's work: dates and progress are dragged, and the data lives in a folder of yours — NAS, Drive or OneDrive — never on a server.

General RC sections
Resistance domains and serviceability checks of reinforced-concrete sections of any shapeSections of any shape, DXF import included: ULS and SLV domains, biaxial bending, moment–curvature and SLS checks on stresses and crack width.

Seismic Isolator HDRB
Design, optimization and verification of circular HDRB seismic isolatorsDesign and verification of circular isolators to EN 15129, EN 1337-3 and NTC 2018, with diameter optimizer, calculation report and F-Δ diagram.

- The paid modules are Seismic Isolator HDRB and General RC sections.
- From the second licence onwards €234/year each (−25%).
- 30-day free trial on the paid modules, with no feature limitations. You start the trial with your e-mail address to open AMetric Toolbox: no payment details.
- Variable loads, Rectangular RC sections, Seismic spectra and Activity Coordination stay free after the trial too.
- Free educational licence for students and teachers, requested from the app with a university document attached.
- The licence is per user and can be moved from one computer to another.
