Solids & surfaces
Breps, extrusions, surfaces and meshes are tessellated and written as real IFC Brep geometry — curved NURBS faces included, at the mesh quality you choose.
Early access · Windows · Rhino 7 & 8 plug-in
Any Rhino object, straight to IFC.
Isometra RHINO2IFC is a Rhino plug-in that exports what is actually in the model — Breps, extrusions, surfaces and meshes, curves (lines, arcs, circles, ellipses, polylines and NURBS), blocks (expanded recursively) and text — to IFC2X3. Not a single-vendor exporter: whatever object types your model has, you choose which ones to send.
Any objectBreps, extrusions, surfaces, meshes, curves, blocks, text and points — not one CAD vendor's own types.
IFC2X3Signed, valid STEP output — checked entity by entity with the xBIM library.
Your choiceScans the model, lists every type it finds, and lets you pick which to export.

RHINO2IFC
One plug-in for whatever the model actually has.
Most CAD-to-IFC exporters only understand one modelling tool's own custom entities. RHINO2IFC works on the Rhino object types themselves, so it works on models from any discipline.
Wireframe geometry
Lines, arcs, circles, ellipses, polylines and NURBS curves export as IFC curves — the geometry that solids-only exporters simply drop.
Blocks, expanded
Block instances are expanded recursively into their real geometry, exactly like Rhino's own Explode — nested blocks included.
Text & points
Text, text dots and points carry through as IFC annotations, so labels and reference points are not silently lost.
Pick your types
Scans the selection or the whole document, lists every object type found with a count, and lets you check or uncheck exactly which ones to export.
Batch export
Convert a folder of .3dm models in the background, without opening each one in Rhino — the same window shows progress for every file.
.ifc.ifczip.obj.3dm
A window inside Rhino, not just commands. Menu, progress bar and a log of what was exported and what was skipped — every command also works from the Rhino command line, for scripting.

FAQ
Good questions.
Which Rhino version does it need?
Rhino 7 or Rhino 8, 64-bit, on Windows. It installs as a plug-in and loads automatically the next time Rhino starts — no manual drag-and-drop needed (though that always works too, as a fallback).
Does it export true NURBS geometry?
No — curves and surfaces are tessellated/sampled, the same way a mesh export works in any 3D tool. A curved surface becomes a triangulated IFC Brep, not an IFC NURBS surface; a NURBS curve becomes a sampled polyline. Shapes come through correctly, just not as exact parametric geometry.
What happens to object types it doesn't recognise?
They are listed in the type picker as not supported in this version (currently hatches and dimensions) and skipped, counted separately from what was exported, so nothing silently vanishes without you knowing.
Is there a limit on the free edition?
The free edition always works — no account, no time limit — with a cap of 25 entities per export and 3 files per batch. A licence removes the cap.
Where does my data go?
Nowhere. RHINO2IFC runs inside your own Rhino and writes files to your own Documents folder. Nothing is uploaded.
