Convert IGES to ABC Online
Convert IGES to ABC in seconds. IGES is an older CAD surface and curve exchange standard; Alembic (ABC)'s strength is this: reliably reproduces complex simulated motion frame-by-frame. No software installation required — everything runs in your browser.

Why Convert IGES to ABC?
The short version: IGES is optimized for exchanging exact surface/curve geometry between legacy CAD systems, Alembic (ABC) is optimized for transferring complex VFX simulations (cloth, fluids, crowds) between studios, and this converter exists for the moment those two needs don't line up.
IGES's limitation: represents a model as separate trimmed surface patches, not a unified solid. Alembic (ABC)'s strength: reliably reproduces complex simulated motion frame-by-frame — it doesn't share that constraint.
Alembic (ABC) was built around transferring complex VFX simulations (cloth, fluids, crowds) between studios, which is precisely the gap IGES leaves open, since it's designed around exchanging exact surface/curve geometry between legacy CAD systems instead.
How to Convert IGES to ABC
- Upload your IGES file.
- MiConvert converts it to ABC, aiming to preserve what makes Alembic (ABC) useful: reliably reproduces complex simulated motion frame-by-frame.
- Download the converted ABC file.
- Use it directly with Maya, Houdini, and other VFX pipelines.
Key Conversion Features
- Fast turnaround, typically under a minute per file
- Bridges the gap between IGES's focus on exchanging exact surface/curve geometry between legacy CAD systems and Alembic (ABC)'s focus on transferring complex VFX simulations (cloth, fluids, crowds) between studios
- No local software installation required for either side — not most CAD systems, not Maya, Houdini, and other VFX pipelines — everything runs in the cloud
- Produces output ready for Maya, Houdini, and other VFX pipelines, picking up right where most CAD systems left off
- Purpose-built for the shift from exchanging exact surface/curve geometry between legacy CAD systems to transferring complex VFX simulations (cloth, fluids, crowds) between studios, not a generic pass-through

Frequently Asked Questions
Can I convert the file back from ABC to IGES afterward?
Only what Alembic (ABC) 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.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Why does ABC exist as a separate format instead of everyone just using IGES?
Because they're built for different jobs — IGES is aimed at exchanging exact surface/curve geometry between legacy CAD systems, while Alembic (ABC) is aimed at transferring complex VFX simulations (cloth, fluids, crowds) between studios. Neither format is "better," they just fit different parts of a workflow.
Do I need any special settings before uploading my IGES file?
No special setup is required — upload the file as-is. IGES files meant for exchanging exact surface/curve geometry between legacy CAD systems convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
What software works with the converted ABC file?
Alembic (ABC) is used by Maya, Houdini, and other VFX pipelines. If you were working with most CAD systems (which produces IGES), this conversion is the direct bridge between the two.
