CAD & 3D Modeling Services

Engineering-ready CAD, product modeling, and production support — from concept to manufacturing.

Tamis Visual Designs provides CAD and 3D modeling services for product development teams, startups, and manufacturers. We help you move from concept to accurate, buildable designs with clean geometry, practical tolerances, and manufacturing-aware decisions.

Whether you need a new part designed from scratch, an existing part improved, assemblies modeled for fit and function, or production-ready files for manufacturing — we can support the full workflow.

Best Fit For

• Product development teams needing reliable CAD for prototyping and production
• Manufacturers requiring clean part files, assemblies, and DFM-ready geometry
• Engineering teams improving parts for strength, tolerance, and assembly
• Startups building MVPs and preparing for manufacturing
• Clients with an existing part that needs redesign, refinement, or reverse-engineered CAD

What We Do

We create accurate, production-aware CAD models and documentation for parts, assemblies, and product systems. Our approach is practical: we model for real-world manufacturing and real-world use.

• Part design and modeling (from concept to manufacturing-ready)
• 3D assemblies with fit and interference considerations
• Design iteration and optimization (strength, function, usability)
• DFM guidance (manufacturability + cost awareness)
• CAD cleanup and repair (fixing broken STLs or messy geometry)
• Conversion (mesh to CAD, 2D to 3D, and production file prep)
• Manufacturing documentation (drawings and technical callouts as needed)

Industries & Use Cases

• Consumer Products: enclosures, mechanisms, housings, ergonomic parts
• Industrial / Manufacturing: fixtures, jigs, tooling aids, replacement components
• Electronics: mounting systems, packaging constraints, assembly planning
• Architecture / Built Environment: specialty components and fabrication-ready models
• Art / Installation: engineered structures and custom mounting solutions

Deliverables

Deliverables depend on your manufacturing process and internal workflow. Common deliverables include:

• STEP / STP (preferred for manufacturing)
• IGES / IGS (as needed)
• STL / 3MF (print-ready prototypes)
• DXF (flat patterns / profiles)
• 2D drawings with key dimensions/tolerances (when required)
• Assemblies + exploded views (optional)
• Revision notes and change tracking (optional)

Why Work With Us

• Manufacturing-aware design decisions — we model for real processes
• Clean, organized files — usable by fabricators, machinists, and vendors
• Fast iteration — we’re built for development cycles
• Prototyping and fabrication support — CAD that can be built immediately
• Clear communication — expectations and requirements stay aligned

Example Project Types

• New product CAD development from rough concept to manufacturable geometry
• Housing/enclosure design for electronics and assemblies
• Assembly modeling to validate fit, tolerances, and fasteners
• Fixture/jig design for manufacturing processes
• Redesign of existing parts to improve durability and manufacturability
• CAD conversion from STL scans to production CAD surfaces

Typical Workflow

1. Discovery — Requirements, use case, and manufacturing intent
2. Modeling — CAD creation and assembly planning (as needed)
3. Review — Revisions, feedback, and iteration
4. Delivery — Export files in required formats with documentation
5. Support — Vendor/manufacturing questions and updates (as needed)

CAD Packages

Every project is different, but these packages represent common needs. We can tailor scope and deliverables based on your workflow.

CAD Cleanup & Conversion

• Fix broken geometry, improve mesh quality, optimize for printing/manufacturing
• Convert files between formats (STL/OBJ → STEP where possible)
• Ideal for vendor handoff and manufacturing prep

Part Design & Modeling

• Create a new part from concept, sketch, or reference part
• Manufacturing-aware modeling and iteration
• Ideal for product development and prototype builds

Assembly & Production Readiness

• Assembly design, fit planning, fastener strategy (as needed)
• Export production-ready files and drawings (when required)
• Ideal for manufacturing handoff and vendor-ready documentation

Common Questions

“Can you work from photos, sketches, or a physical part?”
Yes. We can begin from reference material and/or reverse engineering depending on accuracy requirements.

“Do you provide STEP files for manufacturing?”
Yes — STEP is one of the most common deliverables for manufacturing and vendor handoff.

“Can you redesign a part for better strength or lower cost?”
Absolutely. We often optimize parts for function, durability, assembly, and manufacturing efficiency.

Confidentiality & NDAs

We understand product development work often requires confidentiality. If your project is sensitive, we can work under NDA and coordinate secure file sharing.
