Handing the model on as IFC

IFC is the open format engineers' and consultants' software reads: the structural engineer, the building services planner, the energy consultant. arcraum writes IFC4 in your browser, so the model leaves it only as the file you hand on.

How to

  1. In the editor, open Export in the top bar and choose IFC file (IFC4), or type IFC. On a small screen, open the side panel and choose IFC file (IFC4) there.
  2. The file downloads at once, named after the model (its ISO 19650 name), with the branch's name when you are on another branch than main.
  3. For a signed state, open the project's Releases and click IFC files on the release: each model as the release froze it, one file per model, named with the release ("Release 3").

What is in it

  • The project, site, building and storeys at their heights, a split-level storey's levels as partial storeys, and the georeference from the project's settings.
  • Walls and slabs as real walls and slabs the other software can edit; doors and windows in the holes of their walls; rooms as spaces with their net floor area by DIN 277.
  • Stairs, roofs with their dormers, roof windows, furniture and sanitary objects, and the terrain, as the 3D view shows them.
  • A wall of a wall type carries the type and its layers, from the inside out, each with its material and thickness. Walls without a type, slabs and roofs carry their thickness only: no layers are made up.
  • External and load-bearing, the base quantities (lengths, areas, volumes), the DIN 276 cost groups, the DIN 277 usage groups and your layers (ISO 13567), as the receiving software lists them.

What to expect

  • Each element keeps its id from one export to the next, so the other software can match a new file against the last one.
  • Everything is in it, also what lies on layers you have hidden: the file is the model, not your view of it.
  • Drawings on cuts, dimensions and notes stay out: they are the plan's, not the model's.
  • How a door opens (left or right) is left open in the file: IFC counts it from a side the model doesn't say, and a wrong hand on a door schedule is worse than none.
