About this service

Summary

I create precise CAD models for industrial and consumer products, ready for manufacturing or visualization. With a focus on clean geometry and design intent, I deliver files suitable for prototyping, 3D printing or engineering refinement.

Process

Step 1 – Brief & Reference Gathering You provide sketches, dimensions, or concept references. We clarify the product function, constraints, and use case.

Step 2 – Shared Notion Workspace I include a shared Notion board so you can follow each stage — modeling, reviews, and delivery — in real time.

Step 3 – CAD Modeling I build the 3D model with attention to detail, clean topology and file structure for easy handoff.

Step 4 – Review & Final Adjustments You receive screenshots or previews to confirm geometry and design. Minor adjustments included.

Step 5 – Final Delivery I export the model in the required format and organize everything in a downloadable package. Optional exploded views can be added here.

FAQs

Can you convert concept sketches into CAD models?
Yes, I can model from rough sketches, photos or design references.
Is the file suitable for 3D printing or CNC?
Yes, I can optimize the geometry and export it for your preferred manufacturing method.
Do you offer exploded views or renders?
Yes, as an optional add-on, I can include a photorealistic exploded view or presentation sheet.
