I will reverse engineer 3d scan stl to step cad model


About this gig
Need your STL to STEP conversion done right, not just auto-surfaced? As a Mechanical Engineer, I reverse engineer 3D scans into clean, parametric CAD models accurate, editable, and manufacturing-ready.
What you get:
- Solid STEP/IGES body rebuilt feature-by-feature, not a shrink-wrapped mesh
- Fully dimensioned 2D technical drawing for production
- Native SolidWorks/AutoCAD source files
- Design-intent correction: true dimensions, not scan noise
Why work with me:
I run an industrial reverse engineering practice serving Oil & Gas, Power Generation, Marine, and Aerospace MRO clients, so I model with real tolerances and GD&T in mind CAD built to be machined, not just viewed.
How it works:
1. Send your STL/OBJ/point cloud file
2. Free feasibility review before you order
3. Parametric rebuild plus technical drawing
4. Deliver STEP + native CAD, ready for CNC or molding
Perfect for obsolete parts, damaged components, or scans with no original drawings.
Message me your file before ordering so I can confirm scope and turnaround.

FAQ
What kind of STL/Scan files can you work with?
I can work with most 3D scan data (STL, OBJ, PLY). However, for the best results, the scan should be clear with minimal noise. If your file has significant holes or missing data, please send it to me via message before ordering so I can confirm if it is repairable.
Can you reverse engineer organic shapes (like faces, statues, or artistic sculptures)?
My expertise is in Mechanical Engineering. I specialize in "prismatic" shapes—parts with defined geometry like planes, cylinders, and holes (e.g., gears, brackets, casings).
Where do you ship the physical parts?
I can ship internationally. However, delivery times and shipping costs will vary depending on your location. Please contact me with your country and zip code beforehand so I can give you an accurate shipping estimate.
What if my scan is slightly warped or broken?
I can often deduce the "design intent." For example, if a hole scans as 9.8mm due to shrinkage, I will likely model it as 10.0mm (standard engineering size), unless you instruct me to copy the scan exactly as is.
Do you sign NDAs?
Yes. As a professional engineer, I treat all intellectual property with strict confidentiality. I am happy to sign a Non-Disclosure Agreement (NDA) if required.
Do you offer 3D scanning service?
Yes, we do on additional cost.
Can you convert a raw point cloud directly to a CAD model, or do I need an STL first?
Yes — I can work directly from a point cloud (PLY/XYZ) or a processed STL/OBJ. If you're not sure which format you have, send the raw file and I'll confirm the best path.
Do you handle reverse engineering for obsolete or discontinued spare parts?
Yes, this is one of my most common jobs — recreating manufacturable CAD and drawings for legacy components that have no original design files, so they can be re-machined or re-ordered.
