Convert IGS to PLY Online
Convert IGS to PLY in seconds. IGS (IGES) is the 3-letter extension for the IGES CAD standard; PLY's strength is this: can store per-vertex color and custom properties directly on the mesh. No software installation required — everything runs in your browser.

Why Convert IGS to PLY?
IGS (IGES) is the 3-letter extension for the IGES CAD standard, commonly used for exchanging exact surface/curve geometry between legacy CAD systems. That focus comes with a real limitation: represents a model as separate trimmed surface patches, not a unified solid. PLY doesn't share that problem — its strength: can store per-vertex color and custom properties directly on the mesh.
IGS (IGES)'s limitation: represents a model as separate trimmed surface patches, not a unified solid. PLY's strength: can store per-vertex color and custom properties directly on the mesh — it doesn't share that constraint.
PLY was built around 3D scanning output, carrying per-vertex color alongside geometry, which is precisely the gap IGS (IGES) leaves open, since it's designed around exchanging exact surface/curve geometry between legacy CAD systems instead.
How to Convert IGS to PLY
- Upload your IGS file.
- MiConvert converts it to PLY, aiming to preserve what makes PLY useful: can store per-vertex color and custom properties directly on the mesh.
- Download the converted PLY file.
- Use it directly with 3D scanners and scan-processing software.
Key Conversion Features
- Converts IGS into PLY, aiming to preserve what matters most: can store per-vertex color and custom properties directly on the mesh
- Fast turnaround, typically under a minute per file
- Bridges the gap between IGS (IGES)'s focus on exchanging exact surface/curve geometry between legacy CAD systems and PLY's focus on 3D scanning output, carrying per-vertex color alongside geometry
- 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
- Keeps the parts of your file that matter for 3D scanning output, carrying per-vertex color alongside geometry intact, even though the source was built for exchanging exact surface/curve geometry between legacy CAD systems

Frequently Asked Questions
Do I need any special settings before uploading my IGS file?
No special setup is required — upload the file as-is. IGS (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.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Why would I need PLY instead of just keeping IGS?
Mainly when your workflow specifically calls for 3D scanning output, carrying per-vertex color alongside geometry — that's PLY's whole reason for existing, and IGS (IGES) isn't built to provide it, since it's focused on exchanging exact surface/curve geometry between legacy CAD systems instead.
What software works with the converted PLY file?
PLY is used by 3D scanners and scan-processing software. If you were working with most CAD systems (which produces IGS (IGES)), this conversion is the direct bridge between the two.
Do I need most CAD systems installed to convert my file?
No — the conversion happens entirely on our servers. You don't need most CAD systems, and you don't need 3D scanners and scan-processing software either unless you plan to open or edit the PLY result afterward.
