When delivering Scan-to-CAD documentation, one decision impacts the success of every renovation, retrofit, and construction project: choosing the correct file format. Whether a client needs data for fabrication, BIM coordination, or record drawings, the format you choose—IFC, RVT, or DWG—controls how useful the deliverables actually are.
This guide simplifies the differences between the three most widely used formats in digital construction and explains how to select the right one for laser scan outputs.
🏗️ Why File Format Matters in Scan-to-CAD Projects
Accurate point-cloud conversion is only successful if the output works seamlessly with the stakeholder’s tools.
Choosing the wrong format can lead to:
✔️ Loss of geometry
✔️ Inconsistent layers or model breakdown
✔️ Slow collaboration across platforms
✔️ Costly rework if the model isn’t compatible
Deliverables should serve the client’s workflow, not just the scanner’s output.
🔷 RVT (Revit): Ideal for BIM-Heavy Projects
RVT is the go-to format for BIM-centric Scan-to-CAD workflows. It allows detailed modeling backed by intelligent building elements.
Best For
- Architectural and structural modeling
- MEP design & coordination
- Clash detection workflows
- Smart building documentation
- Renovation with detailed building systems
Why Choose RVT
- Supports parametric families
- High-precision modeling for LOD 300-500
- Faster coordination and scheduling
When It’s Not Ideal
- When clients don’t use Revit
- When only 2D drawings are required
🌐 IFC (Industry Foundation Class): Open & Interoperable
IFC is a neutral BIM file format designed for cross-software exchange. If multiple project teams work on different software platforms, IFC prevents dependency on proprietary tools.
Best For
- Government projects requiring open BIM
- Multi-stakeholder collaboration (ArchiCAD, Revit, Tekla, Navisworks, etc.)
- Facilities management handover
Why Choose IFC
- Universal format across BIM platforms
- Reduces data loss when sharing models
- Ideal for open standards and long-term archiving
When It’s Not Ideal
- When deep parametric editing is required
- Not as smooth for fabrication workflows
📐 DWG (AutoCAD): Perfect for Drafting & 2D Deliverables
DWG is still the industry backbone for construction documents and precise drafting. Scan-to-CAD projects often deliver floor plans, elevations, sections, and site layouts in DWG format.
Best For
- Permit drawings & documentation
- 2D construction plans for contractors
- Shop drawings
- As-built documentation for facility teams
Why Choose DWG
- Universally accepted by engineers, architects, contractors
- Lightweight, easy to share and edit
- Supports both 2D and 3D drafting
When It’s Not Ideal
- Not suitable for full BIM modeling
- Lacks intelligent building data
🛠️ How to Choose the Right Format for Your Client
Use the decision points below before finalizing Scan-to-CAD deliverables:
Pro Tip: Many successful projects deliver a hybrid—RVT + DWG, or RVT + IFC, depending on scope.
📌 Future Trend: Hybrid Deliverables Will Dominate
With growing BIM adoption and cloud collaboration, the industry is moving toward mixed deliverables that meet each stakeholder’s workflow. Expect RVT models for BIM teams, IFC for open sharing, and DWG drawings for field execution.
🎯 Conclusion
Choosing between IFC, RVT, or DWG isn’t just a technical step—it’s a strategic decision that affects cost, clarity, collaboration, and construction accuracy.
✔️ Choose RVT for BIM intelligence
✔️ Choose IFC for universal exchange
✔️ Choose DWG for drafting-ready deliverables
A successful Scan-to-CAD project starts not with the scanner, but with understanding how the final data will be used.
