Convert NC to 3DM Online
Convert NC to 3DM in seconds. NC (G-code) is CNC machine movement instructions; 3DM (Rhino)'s strength is this: exact curved-surface precision for freeform shapes. No software installation required — everything runs in your browser.

Why Convert NC to 3DM?
NC (G-code) works well for describing a mill, router, or laser's toolpath, but has a real limitation: isn't a drawing or model — there's no native shape to open. Converting trades that for this: exact curved-surface precision for freeform shapes.
NC (G-code)'s limitation: isn't a drawing or model — there's no native shape to open. 3DM (Rhino)'s strength: exact curved-surface precision for freeform shapes — it doesn't share that constraint.
NC (G-code) is typically produced by or used with CAM software and CNC controllers, for describing a mill, router, or laser's toolpath. 3DM (Rhino) is expected by Rhinoceros instead, for freeform industrial design, jewelry, and architectural modeling — converting bridges that gap.
How to Convert NC to 3DM
- Upload your NC file.
- MiConvert converts it to 3DM, aiming to preserve what makes 3DM (Rhino) useful: exact curved-surface precision for freeform shapes.
- Download the converted 3DM file.
- Use it directly with Rhinoceros.
Key Conversion Features
- Converts NC into 3DM, aiming to preserve what matters most: exact curved-surface precision for freeform shapes
- No local software installation required for either side — not CAM software and CNC controllers, not Rhinoceros — everything runs in the cloud
- Keeps the parts of your file that matter for freeform industrial design, jewelry, and architectural modeling intact, even though the source was built for describing a mill, router, or laser's toolpath
- Produces output ready for Rhinoceros, picking up right where CAM software and CNC controllers left off
- Purpose-built for the shift from describing a mill, router, or laser's toolpath to freeform industrial design, jewelry, and architectural modeling, not a generic pass-through

Frequently Asked Questions
What happens to features specific to NC that 3DM doesn't have?
NC (G-code)'s real strength — an exact record of the machine operation that will be performed — has no equivalent once converted, since 3DM (Rhino)'s constraint is: tied to Rhino's own file structure, which most other 3D software can't open directly.
Why would I need 3DM instead of just keeping NC?
Mainly when your workflow specifically calls for freeform industrial design, jewelry, and architectural modeling — that's 3DM (Rhino)'s whole reason for existing, and NC (G-code) isn't built to provide it, since it's focused on describing a mill, router, or laser's toolpath instead.
Can I convert the file back from 3DM to NC afterward?
Only what 3DM (Rhino) actually carries can come back — anything specific to NC (G-code)'s role in describing a mill, router, or laser's toolpath that didn't survive the original conversion won't reappear.
