How to convert SAT to IGS
- Add your .SAT file - drop it in the box above or click to browse.
- Convert it to .IGS in a few seconds.
- Download your new .IGS file.
What to expect
- A closed ACIS solid may become a collection of surfaces in IGES, sometimes requiring surface healing downstream.
- Both formats are plain-text geometry only; no build history or executable content is involved.
- Units and tolerances should be checked after conversion, as neutral exchange can introduce small mismatches.
Frequently asked questions
How faithful is the geometry after converting SAT to IGES?
Both are neutral CAD exchange formats, so overall shape transfers well, but IGES is surface- and wireframe-oriented and a watertight ACIS solid can come across as a set of surfaces rather than a single closed solid.
Why convert a SAT model to IGS?
IGES is a vendor-neutral ASCII standard that almost every CAD system can import, so it is a common bridge when the receiving program does not read ACIS SAT directly.
Which programs open an IGS file?
IGES is widely supported and can be viewed free in FreeCAD or Open Cascade CAD Assistant and imported by most professional CAD packages.
What is commonly lost between SAT and IGES?
Solid topology and assembly structure may not survive intact; IGES often represents a part as trimmed surfaces, which can leave small gaps that need healing before reuse.
