Expected duration: 1 - 2 weeks I am developing a public art sculpture and have created an initial Rhino 3D model. The design is at a good stage conceptually, but I need technical support to make it fabrication-ready.
Key Tasks
-Align and flatten CPlanes where curves/surfaces are not lining up correctly. -Tidy up and refine curves/surfaces so they are closed, watertight, and fabrication-ready. -Check the internal metal framework (to be laser-cut and sent to a fabricator). -Improve alignment of the external copper shell components so they sit correctly around the framework. --The shell will be fabricated from copper sheet, separated into individual pieces, and riveted to the internal framework. --The horn section has been particularly challenging and will need careful adjustment. -Review sweep surfaces (working in some areas but not in others) and rebuild/adjust where needed. -Ensure the model is structurally sound and properly aligned for future detailing (e.g. rivet points between shell and framework). -Create layered files showing each component required for manufacturing/laser welding.
Deliverables -A cleaned, aligned Rhino 8 model. -Surfaces corrected and closed so the design is ready for digital fabrication and prototyping. -The internal structure flattened for laser cutting, so I can make a 1:3 scale prototype model first. -Guidance/notes on adjustments made so I can continue developing the model myself. -Provide accurate widths/dimensions of the internal and external copper trumpet (horn) shapes, so that I can obtain a fabrication quote for these parts.
Background
This is an art sculpture combining a stainless steel internal structure with a copper shell. I have pushed my Rhino skills as far as I can but now need an experienced CAD designer to refine the model and make it technically robust.
The internal steel structure thickness may need to remain adjustable (currently aiming for 2.5 mm on the horns and flanges, with 6 mm flanges at the base). The copper sheet is 1.5mm.
Requirements
-Strong proficiency in Rhino (curves, surfaces, CPlane management). -Experience preparing CAD models for metal fabrication/laser cutting. -Understanding of sheet metal, sculpture, or fabrication workflows is highly desirable.
Communication & Workflow
-I would like an initial video call to walk through the model and confirm requirements. -Feedback (a video call) would be helpful, so I can learn from mistakes in my sketch/model and improve my Rhino workflow.
Budget & Priority
The budget is for the full scope above.
- Phase 1 priority: Curve/surface alignment + internal structure flattened for laser cutting (so a prototype can be made quickly). - Phase 2: Copper shell refinement and flattening for fabrication.
Further detailing or any additions to the piece after the prototype stage can be discussed separately. For example, this may include: -Riveting points connecting the copper to the stainless steel. -The amount of copper overlap needed, and how to make a clean detail at joint lines. -Whether a connection is required between the two sculptures, and if so, where it could go and what it might look like.
Thank you for your time and look forward to hearing back from you.
