CAD Refinement for 3D Dog Sculpture

Project Title:
Minor Curve Adjustment + CAD Conversion for Balloon Loop Dog Sculpture

Project Description:
I have a 3D model of a sculpture called Balloon Loop Dog.
The side view (profile) is already complete in Blender, but the front view needs slight curvature adjustments to improve the flow and continuity of the loop.

This project is not for full fabrication drawings.
I only need light CAD work to refine the front-view curves and prepare a clean CAD version of the model.
The final detailed fabrication CAD will be done later by a professional stainless-steel manufacturer.

I will provide:
- Blender file (.blend)
- OBJ/MTL
- Render images
- Reference views

What I need:
- Adjust the front-view curvature to make the loop smoother and more natural.
- Maintain the pipe diameter of 160 mm.
- Convert the refined model into CAD (Rhino, SolidWorks, or AutoCAD).

Scale:
3.6 m W × 0.7 m D × 2.9 m H

Material for final sculpture: Stainless Steel (but full fabrication CAD is NOT required at this stage)

Goal:
Produce a refined CAD model with corrected front-view curves.
