2D CAD in, semantic IFC4 out, deterministic — and everything Structura had to decide is shown to you, against the drawing, before you accept it. Not a black box.
Structura converts a set of DXF sheets into an IFC4 Reference View model with named storeys, classified elements, rooms and the data attached to each of them. You review what it found against crops of the drawing it found them in, correct what is wrong, and export a file your BIM tools already understand.
An element you did not touch keeps the same IFC identifier every time the model is exported, so your model server sees a revision rather than a new building. An element that genuinely moved gets a new one, and nothing else changes.
Every release is measured before it ships, against a benchmark set we build ourselves — and the page says plainly what that does and does not prove about your drawings.
Where a drawing does not say, Structura has to assume something — and every assumption is written down, with what it applies to and what it affects, and delivered with the model. Nobody discovers it during a handover.
Floor plans give the footprint: walls, openings, columns, stairs and room regions. Elevation sheets give the vertical story: storey heights, sill and head levels. The two are reconciled into one stack of storeys.
A 3D export instead of line work: the same element classes are recovered from the geometry, including pitched roofs, which plans cannot show.
Anything else is refused with a clear reason rather than a half-built model.
Read the limits →The sample on this page is 6 storeys and 265 elements, converted from 8 DXF sheets and reviewed in the browser. Send us a set of your own and we will convert it with you, then hand back the IFC, the schedule and the assumptions register.
