Convert IGES to 3DM Online
Convert IGES to 3DM in seconds. IGES is an older CAD surface and curve exchange standard; 3DM (Rhino)'s strength is this: exact curved-surface precision for freeform shapes. No software installation required — everything runs in your browser.

Why Convert IGES to 3DM?
This conversion comes up whenever you need freeform industrial design, jewelry, and architectural modeling instead of exchanging exact surface/curve geometry between legacy CAD systems. IGES and 3DM (Rhino) serve genuinely different purposes, so moving between them isn't just a formality.
IGES works well for exchanging exact surface/curve geometry between legacy CAD systems, but has a real limitation: represents a model as separate trimmed surface patches, not a unified solid. Converting trades that for this: exact curved-surface precision for freeform shapes.
IGES's limitation: represents a model as separate trimmed surface patches, not a unified solid. 3DM (Rhino)'s strength: exact curved-surface precision for freeform shapes — it doesn't share that constraint.
How to Convert IGES to 3DM
- Upload your IGES 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
- Produces output ready for Rhinoceros, picking up right where most CAD systems left off
- Converts IGES into 3DM, aiming to preserve what matters most: exact curved-surface precision for freeform shapes
- Fast turnaround, typically under a minute per file
- Free for files up to 50MB, 100MB for registered accounts
- Built to handle the real-world quirks of files meant for exchanging exact surface/curve geometry between legacy CAD systems, not just a textbook version of the format

Frequently Asked Questions
What software works with the converted 3DM file?
3DM (Rhino) is used by Rhinoceros. If you were working with most CAD systems (which produces IGES), this conversion is the direct bridge between the two.
Will I lose anything converting IGES to 3DM?
Converting to 3DM (Rhino) means adapting to a real constraint: tied to Rhino's own file structure, which most other 3D software can't open directly. Anything IGES carries — built as it is for exchanging exact surface/curve geometry between legacy CAD systems — that has no equivalent there won't make the trip, but the core content converts faithfully.
Can I convert the file back from 3DM to IGES afterward?
Only what 3DM (Rhino) actually carries can come back — anything specific to IGES's role in exchanging exact surface/curve geometry between legacy CAD systems that didn't survive the original conversion won't reappear.
What happens to features specific to IGES that 3DM doesn't have?
IGES's real strength — still widely supported across older and current CAD software alike — 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.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
