Collins
About this gig
GIG DESCRIPTION
Mechanical and Industrial Design Engineer with 3+ years experience converting raw scan data into clean, editable geometry. I reconstruct point cloud mesh scans into parametric nurbs autocad dwg models with accurate tolerances and feature histories.
Services I Offer:
- Point cloud filtering, decimation, and alignment
- Mesh-to-NURBS surface reconstruction
- Parametric CAD feature extraction & history trees
- Deviation analysis & surface accuracy verification
- Wall thickness, rib, and mounting feature restoration
- 2D technical drawings generated from scanned geometry
- Solid body conversion for CNC machining & tooling
Tools I Use:
- Geomagic Design X, AutoCAD, SolidWorks, Rhinoceros 3D
File Formats Delivered:
- DWG, DXF, STEP, IGES, SAT, OBJ, STL, PDF
Why Work With Me?
- Unlimited Revisions to ensure exact physical fit
- True editable feature geometry over quick auto-surfacing
- Manufacturing alignment for toolpaths and casting
- Strict error boundary verification against raw mesh
Please message me to discuss your project requirements before placing a direct order.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

FAQ
What raw scan file formats can you process?
I work with point cloud and mesh exports including STL, OBJ, PLY, PTS, E57, XYZ, LAS, and ASC formats.
What is the difference between automatic surfacing and parametric NURBS reconstruction?
Auto-surfacing overlays non-editable patches on points, whereas parametric reconstruction builds clean cylinders, planes, sketch curves, and editable features for downstream modification.
How accurate is the final DWG model compared to my raw scan data?
Geometry is rebuilt within defined deviation thresholds, typically within ±0.05mm to ±0.1mm depending on scan resolution and target manufacturing process.
Can missing, broken, or worn sections of a scanned physical part be restored?
Yes, incomplete regions or damaged features are restored using symmetry, geometric intent, and exact mechanical dimensions during CAD reconstruction.
5 Q: What software tools are utilized during the reverse engineering process?
Dedicated reverse engineering suites like Geomagic Design X are used alongside AutoCAD and SolidWorks to extract clean features and native DWG trees.
What is your revision policy if physical test-fitting reveals alignment discrepancies?
I provide Unlimited Revisions on every package tier to fine-tune CAD dimensions, surface boundaries, and mounting hole centers until the model fits physical hardware.
Will I receive native editable CAD files or just dumb surfaces?
You receive fully editable, parametric CAD files with clean feature trees in AutoCAD DWG, SolidWorks SLDPRT, or universal NURBS STEP formats.
