Parametric BIM

Refine what matters,
as deeply as you want.

Build parts, combine them, and shape architecture. As space in zoning, as a frame in structural study, as members in detailing — how you see the building, and what you engage with, shifts by phase. Strura is a Parametric BIM that lets you design to each of them.

Live Demo

Everything you place carries meaning.

Place walls, slabs, stairs, furniture, and a roof to assemble a two-story house. The 2D view, the 3D view, the node graph, and the cost and area figures update in real time with every action. Because each object carries meaning, analysis is instant.

Broad concepts and fine details alike —
they take shape on one model.

The Core Idea

From start to finish,
one model.

In conventional BIM, the model is rebuilt at every step — concept, schematic design, detailed design — and information is lost each time.

A Strura model stays one model from start to finish. As phases advance, what switches is not the model but how you see it and what you can do: a volume during zoning, columns and beams during structural study, individual parts during detailed design — the same object at different levels of precision.

Area, cost, quantities, code requirements, and structural constraints live on the objects themselves, so changing one thing updates exactly the numbers it affects.

Analysis Prepare a separate model Run on the same objects
Propagating changes Synced by hand Auto-updates only what's affected
03 / Difference

Why Strura

Three things other tools don't do.

01

Parametric and BIM, unified

Design parts and logic as nodes, and they become BIM data as-is. No shuttling between a modeling tool and BIM software.

02

Phases advance; the model carries over

From zoning to detailed design, the same model is handled in the view each phase needs. With no rebuilds or transcription, decisions and their rationale are never lost.

03

Different roles, one shared dataset

An individual's concept, an architect's design, a maker's products — all connected on one building dataset. No rebuilding information at every handoff.
