Understanding Scan-to-CAD Pricing
Scan-to-CAD is the essential process of taking raw 3D laser scan data (points or polygon meshes) and converting it into a clean, editable, feature-tree-based engineering model compatible with software like SolidWorks or Fusion 360.
Because this requires manual design labor rather than automated conversion, pricing depends heavily on the complexity of your part's geometry and the level of precision required.
Local Service Bureau Pricing Tiers
Professional engineering bureaus in South Africa generally structure Scan-to-CAD services across hourly rates and project tiers:
Hourly Modeling Rates:
Many local providers charge a technical design rate starting around R350.00 per hour (excl. VAT), scaling upward based on the complexity of the parametric deliverables.
Simple Geometry (R1,500 – R3,500): Ideal for straightforward components like flat brackets, simple covers, or uniform plates that require fast parametric recreation.
Moderate Complexity (R3,500 – R7,500): Geared toward mechanical housings, gears, pulleys, and casings featuring bolt patterns, fillets, and standard mating features.
Complex Assemblies & Organic Shapes (R7,500 – R25,000+): Multi-part mechanisms, complex internal fluid channels, or freeform organic shapes requiring extensive manual surfacing and assembly structuring.
Key Factors That Influence Scan-to-CAD Costs
Mesh Quality & Preparation:
If a raw scan contains noise, holes, or missing data due to deep cavities, cleaning the polygon mesh takes extra engineering hours before modeling can even begin.
Tolerance and Fitment Requirements:
Designing a part for visual prototyping requires far less precision than engineering a component for high-stress CNC machining or strict manufacturing tolerances.
Parametric vs. Non-Parametric Design:
Building a basic surface model is quicker, whereas creating a fully parametric CAD file with a functional timeline and editable history tree requires significantly more skilled labor.
Getting the Best Value for Your Project
Converting physical parts into digital CAD models bridges the gap between old hardware and modern manufacturing, making part reproduction and custom design seamless.
By identifying whether your project requires a quick functional fit or a rigorous, production-ready engineering file, you can accurately budget your next Scan-to-CAD investment without paying for unnecessary design complexity.
Additionally, investing in proper CAD conversion saves long-term maintenance expenses by establishing a reliable digital archive for obsolete components, ensuring your manufacturing workflow never faces costly downtime due to missing replacement parts.
