🧊 General 3D Modeling, CAD & Mechanical Design

General CAD, 3D modelling and mechanical design tools produce geometry rather than building information: lines, surfaces, solids and meshes without the object semantics (wall, door, slab) that BIM authoring tools attach and that IFC carries between platforms. In AEC they sit around the BIM model: 2D drafting and legacy DWG/DGN drawings, concept massing and facade studies, fabrication and product design for building components, and visualisation or animation of the finished design. Understanding where geometry-only tools end and information-rich BIM begins is what lets a team move data between them without losing meaning.

Autodesk AutoCAD

AutodeskThe industry-standard 2D/3D drafting platform and the origin of the DWG format.General 3D Modeling, CAD & Mechanical DesignSubscriptionWindowsmacOS

AutoCAD is Autodesk's general-purpose drafting and modelling application, first shipped in 1982 and now sold as AutoCAD 2027 with specialised toolsets (Architecture, MEP, Mechanical, Electrical, Map 3D, Plant 3D, Raster Design) bundled in the subscription. It produces precise 2D drawings and 3D solid, surface and mesh geometry in the DWG format that nearly every AEC tool can read. In BIM workflows it is used for detail drawings, legacy drawing sets, survey and site linework, and as a DWG underlay in Revit, Archicad or Civil 3D. It carries no building object semantics unless a toolset such as AutoCAD Architecture is used.

Vendor: Autodesk
Current version: AutoCAD 2027 · 2026
First release: 1982
Official site: autodesk.com/products/autocad/overview
Platforms: WindowsmacOS

Native formats: .dwg.dxf.dwt.dws
Exchange formats: DWGDXFDWFPDFDGNSATSTLFBX3DSIGESSTEP
IFC: import: No · export: No
openBIM notes: Plain AutoCAD has no IFC support. The AutoCAD Architecture and MEP toolsets (included in the AutoCAD subscription) add IFC import/export and object-based building elements. In openBIM workflows AutoCAD is usually a 2D deliverable or a DWG reference underlay for BIM authoring tools.
Automation & APIs: AutoLISP / Visual LISPObjectARX (C++).NET APIVBAAction RecorderAutodesk Platform Services (APS)
Learning curve: Medium — Basic 2D drafting is learned in weeks; 3D, toolsets and customisation take considerably longer.
Typical users: DraftersArchitectsCivil and MEP engineersSurveyorsFacilities managers
Works with: Autodesk Revit Autodesk Civil 3D Autodesk Navisworks (Manage / Simulate / Freedom)BricsCAD BIM SketchUp (Pro / Studio)Bentley MicroStation Autodesk Construction Cloud (Autodesk Forma)

AutoCAD Web and mobile apps for viewing and light editing
Automation with AutoLISP, .NET, ObjectARX and Action Recorder
Autodesk Assistant AI help built into the 2027 release

Strengths

De facto DWG standard read by almost every AEC application
Very large user base, training market and third-party add-on ecosystem
Mature customisation and automation options
Toolsets extend it into discipline-specific drafting without another product

Limitations

No object semantics or information model in core AutoCAD
No native IFC support without the Architecture/MEP toolsets
Subscription-only licensing since 2016
Coordination of multi-discipline 3D models is far weaker than in BIM tools

Best for: 2D construction documentation, legacy DWG drawing maintenance and detail drafting that sits alongside a BIM model.

Market notes: Still the most widely installed CAD application in AEC; many public-sector and infrastructure clients continue to require DWG deliverables alongside BIM models.

FreeCAD is a free, LGPL-licensed parametric 3D modeller developed by the FreeCAD project association, with version 1.1.3 released in July 2026. It uses the OpenCascade kernel and a workbench structure covering sketching, part design, assemblies, TechDraw drawings, CAM and a BIM workbench with IfcOpenShell-based IFC support. Small practices, researchers and public bodies use it for mechanical parts, building components and openBIM experiments without licence cost. The core data model is parametric geometry, with building semantics added by the BIM workbench.

Free and open source on all desktop platforms
Real parametric history unlike SketchUp or Blender
Native IFC through IfcOpenShell
Transparent Python data model

Limitations

Interface and stability lag commercial CAD
DWG needs an external converter
Documentation output is basic
No official certification

Best for: Zero-cost parametric modelling and IFC authoring where a commercial licence is not justified.

Build a parametric facade in Grasshopper and push it into Revit as curtain panels or adaptive components through Rhino.Inside.Revit
Take a SOLIDWORKS or Inventor assembly of an air-handling unit, simplify it and publish an RFA with duct and electrical connectors plus an IFC; load into Revit and check connector behaviour
Convert a MicroStation DGN survey to DWG with a level-to-layer mapping table and verify the coordinate system in Revit and Civil 3D
Diagnose three broken exchanges supplied by the trainer (wrong units, far origin, exploded proxies) and document the fix

Outcome: The learner can run geometry-to-information hand-offs on a real openBIM project and diagnose the common failures.

Level 4

Expert

30 h

Skills you will build

Automate AutoCAD with AutoLISP or .NET and batch DWGs with Design Automation in Autodesk Platform Services
Script Blender headless with Python and IfcOpenShell for IFC processing, mesh reduction and batch rendering
Design Grasshopper, RhinoCommon and Rhino Compute pipelines that write results to Revit or IFC
Build configurable BIM content with Inventor iLogic, Onshape FeatureScript and the REST API, or the SOLIDWORKS API
Define an office CAD/3D governance standard: platform choice, licensing, templates, naming aligned to ISO 19650, data residency and API portability

Software focus: Autodesk AutoCAD, Blender, Rhinoceros 3D (Rhino), Autodesk Inventor, Onshape, SOLIDWORKS, Autodesk Fusion

Practice exercises

Write an AutoLISP or C# tool that audits a folder of DWGs against the office layer standard and reports violations; test the LISP version in BricsCAD and ZWCAD
Create a headless Blender script that opens an IFC with IfcOpenShell, colours elements by IfcType and renders four fixed cameras to PNG
Publish a Grasshopper definition through Rhino Compute and call it from a small web page that returns panel geometry as glTF
Configure one master Inventor or Onshape model of a modular component with rules so that ten catalogue variants are exported automatically as STEP and RFA/IFC
Draft a two-page CAD and 3D platform standard for a 50-person practice covering tool selection, licences, templates, naming, exchange formats and automation ownership

Outcome: The learner can automate CAD and 3D work across tools and set governance for how geometry-based software feeds a BIM programme.

Tips from our consultants

Decide the geometry-to-information hand-off point per project: model concept in SketchUp or Rhino, but move to a BIM tool before documentation and quantities are needed.
Always model near the origin, in the project units, and agree a shared coordinate point before exchanging DWG, DGN or 3DM files.
Prefer B-rep formats (STEP, SAT, 3DM) for precise geometry and mesh formats (FBX, glTF, OBJ) only for visualisation.
Keep automation in portable languages where possible: AutoLISP runs in AutoCAD, BricsCAD and ZWCAD; Python runs in Blender, FreeCAD, Rhino and Fusion.
Validate every IFC you export in a second tool (Bonsai, Solibri or BIMcollab Zoom) before it goes to the CDE.
Track vendor licence changes: AutoCAD, 3ds Max, Inventor and Cinema 4D are subscription only, while Rhino, BricsCAD and ZWCAD still sell perpetual licences.
Do not assume a certification claim: check the buildingSMART certified-software register for the exact product, version and exchange before relying on IFC output contractually.
