DWG vs RVT vs IFC — File Formats Explained for Beginners
Confused by CAD file formats? Simple explanation of DWG (AutoCAD), RVT (Revit), and IFC (universal BIM) — what each is, when you'll encounter them, and how to handle them.
Who This Guide Is For
You'll encounter many file formats in CAD. The three most important in architecture/engineering are DWG, RVT, and IFC. Here's a plain-English explanation of what each is and when you'll need them.
Software Covered
Key Things to Consider
- DWG = AutoCAD's format. The most common 2D/3D drawing file. Almost universal.
- RVT = Revit's format. Contains a complete building information model. Only opens in Revit.
- IFC = Universal BIM format. Any BIM software can open it. Used for sharing between different programs.
Your Options Explained
AutoCAD (DWG)
DWG files contain geometry (lines, arcs, text) in 2D or 3D. They're the most widely exchanged CAD file type. Almost every CAD program can open DWG. You'll see these everywhere.
Revit (RVT)
RVT files contain an entire building model with intelligent objects (walls know they're walls, doors know their fire rating). Much richer data than DWG but only works in Revit.
Our Recommendation
Rule of thumb: DWG for 2D drawings and simple 3D. RVT when working in Revit teams. IFC when sharing BIM models between different software (e.g., architect uses Revit, structural engineer uses Tekla). Don't stress about this early — you'll learn naturally as you work.

Decision Criteria & Engineering Considerations
When evaluating software options for DWG vs RVT vs IFC — File Formats Explained for Beginners, engineering teams must balance upfront licensing costs against multi-year training productivity. Interoperability across neutral formats (STEP AP242, IFC 4x3, and native DWG) is paramount to avoid data isolation across consultant teams.
Modern engineering workflows require hardware with high single-core processor clock speeds (3.8 GHz+) and dedicated GPUs with 8GB+ VRAM to ensure fluid 3D viewport rotation and rapid drawing regeneration.
