🏛️ BIM Authoring — Architecture & Building Design
Architectural BIM authoring tools are where the building model is created: walls, slabs, roofs, openings, stairs and spaces are modelled as intelligent objects that carry geometry and data at the same time. From that single model the team produces plans, sections, schedules and quantities, and exchanges the design with structural, MEP and construction teams through native links or open formats such as IFC and BCF. This category covers full BIM authoring platforms, lighter or early-stage design tools that hand over to them, and the products that have been retired or replaced.
Autodesk Revit
AutodeskAutodesk's multidiscipline BIM authoring platform for architecture, structure and MEP.BIM Authoring — Architecture & Building DesignSubscriptionWindowsIFC ⇄
Revit is a parametric building modelling application in which a single project database drives all plans, sections, elevations and schedules. It is used by architects, structural engineers, MEP engineers and contractors, often on the same central model through worksharing on a local server or through Revit Cloud Worksharing. Revit 2027 makes the application a Forma Connected Client, so early-stage site and building studies from Forma can flow into Revit as native, geolocated models. It is the reference authoring tool in most Autodesk-centred pipelines that continue into Navisworks, Autodesk Construction Cloud and Twinmotion.

🏛️ Architectural BIM Authoring: from first model to multi-platform lead
Estimated hours: 160For architects, technologists and BIM modellers who need to produce reliable building models and documentation in a BIM authoring platform and exchange them with other disciplines. Learners start in one platform (Revit or Archicad), add openBIM exchange and coordination skills, and finish able to standardise, automate and govern authoring across several tools in a practice.BIM ModelerArchitectural TechnologistBIM CoordinatorBIM Manager
Prerequisites: Reading architectural drawings (plans, sections, elevations) · Basic understanding of building construction · Comfortable with Windows or macOS file management · Access to an education or trial licence of Revit or Archicad
Foundation
30 h- Explain what BIM authoring is and how it differs from CAD drafting, viewers and coordination tools
- Navigate the interface, views and project browser of Revit or Archicad
- Model levels, grids, walls, floors, roofs, doors and windows using building elements
- Identify native and exchange file formats (.rvt/.rfa, .pln, .vwx, .dwg, IFC) and what each is for
- Describe the main products in the category, their vendors, platforms and pricing models
Software focus: Autodesk Revit, Graphisoft Archicad, SketchUp (Pro / Studio)
Practice exercises- Model a two-storey house from a given plan and section set in Revit or Archicad, with correct levels and wall build-ups
- Produce a plan, two sections and an elevation on sheets with a titleblock

- Export the model to IFC4 Reference View and to DWG, then open both in a free viewer and record what data survived
- Repeat a small model in BricsCAD BIM or Vectorworks to experience a second platform's workflow
Outcome: The learner can deliver a coordinated documentation set from a shared model and produce clean exchange files for consultants.
Professional
50 h- Configure IFC export mapping (Revit export setups and property-set mapping; Archicad translators) for specific consultants
- Manage BCF issue rounds between different authoring tools and a checker such as Solibri or BIMcollab
- Apply ISO 19650 concepts: information requirements, BIM execution plan, container naming and shared coordinates
- Validate models against an IDS and fix classification and property gaps at source
- Plan concept-to-BIM hand-overs from Forma, Snaptrude, SketchUp or Rhino/VisualARQ into the authoring platform
- Diagnose common problems: wrong origin, missing storeys, duplicated elements, broken links
Software focus: Autodesk Revit, Graphisoft Archicad, Allplan, Autodesk Forma, Snaptrude, VisualARQ (BIM for Rhino)
Practice exercises- Write the exchange section of a BIM execution plan for an architect in Archicad and a structural engineer in Revit

Tips from our consultants
- Learn one platform properly before adding a second; the concepts transfer but the habits do not.
- Always check your IFC export in a neutral viewer before sending it; certification covers the software, not your settings.
- Agree shared coordinates, levels and naming in the BIM execution plan before anyone models a wall.
- Keep templates, content and scripts in version control and pin software versions per project.
- Use the free tiers and trials (Snaptrude, SketchUp Free, Revit and Archicad education licences) to practise exchange between tools.
- Treat AI assistants and cloud connectors as tech previews until your practice has tested them on a real project.
