Yes to both. There is no charge and no licence fee. The objects are published so that what you draw matches what we manufacture — you may place them in any drawing set, tender package or model, including projects that ultimately use another supplier.

We ask only that you do not redistribute them as your own content, and that you keep the type codes intact so the doorset can be traced back to its test report.

Two honest reasons. First, so that we can tell you when a file changes — a revised detail, a new rating, or the native Revit families when they ship. A fire door detail that has quietly gone out of date inside your office template is a real problem, and we would rather be able to reach you.

Second, because knowing which practices are specifying which types is how we decide what to publish next. One registration covers the whole library; you will not be asked again.

The IFC4 objects open in every mainstream BIM authoring tool and viewer:

• Revit 2021 and later — Insert → Link IFC, or File → Open → IFC
• ArchiCAD 24 and later — native IFC import, geometry and properties intact
• Tekla Structures, BricsCAD BIM, BlenderBIM / Bonsai
• Any IFC viewer for checking — Solibri, BIMcollab ZOOM, usBIM, Navisworks

The DWG details open natively in AutoCAD, and in BricsCAD, ZWCAD, DraftSight and any DWG-compatible CAD. They can be placed as a drafting view or attached as an external reference. The PDFs are print-ready at A3.

If your office standard is DXF rather than DWG — or you are on a tool that only reads DXF — ask and we will send the same detail in that format.

Not yet, and we would rather say so plainly. The authoring specification, shared parameter file and type catalogues for five families covering all thirteen products are complete. The families themselves have not been released.

Until they are, the IFC objects import into Revit but arrive at a fixed size and are not wall-hosted. Use them for coordination, clash checking and schedule data — not as parametric door families you resize per opening. Tick the box on the registration form and you will get one email when they ship, and nothing else on that list.

Each object carries its fire rating, IS 3614 classification, core construction, frame section and seal specification as structured properties, alongside the standard Pset_DoorCommon set. The doorset schedules directly out of the model instead of being typed in by hand, and the data round-trips when the model is exchanged.

Geometry follows the shop drawings, is modelled in millimetres at the catalogue reference size, and is validated with IfcOpenShell before release.

Expected — the library is published at catalogue reference sizes, and most projects need something else. Send the opening schedule and we will confirm what is achievable within the tested range, then issue a project-specific detail.

Note that ISI-marked doorsets are covered by a BIS licence up to 1200 × 2400 mm; beyond that the doorset is supplied against its test report rather than the ISI mark, and we will say which applies before you specify it.

72 hours. After that, request a fresh copy with the same email address — there is no second registration and no waiting. A copy of every link is also emailed to you at the time of the request, so the files stay reachable from your inbox.

No. There is no obligation attached to the download, and we do not treat it as one.

What we would ask is that if the drawing carries our detail, the doorset that gets installed matches it. A tested assembly is only worth what the built assembly reproduces — substituting an uninsulated leaf into a detail drawn for a fully insulated one leaves the certificate behind, and under NBCS 2026 it leaves compliance behind too.
