How to convert X_T to IGS
- Add your .X_T 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
- Exact surface and curve geometry is preserved; both formats store true B-rep data rather than a triangle mesh.
- Solid bodies may be exported as trimmed-surface sets, which can introduce small gaps or require stitching in the receiving CAD program.
- Parametric history, feature tree, assembly relationships and material data do not exist in IGES and are lost.
Frequently asked questions
Does the converted IGES keep the exact geometry of the Parasolid model?
The precise B-rep geometry transfers, since both
X_T and IGES describe exact surfaces rather than a mesh. However, IGES often represents a solid as a set of trimmed surfaces rather than one watertight body, so small gaps or tolerance mismatches can appear where surfaces meet.Why convert an X_T file to IGS?
X_T is the proprietary Parasolid transmit format, readable mainly by Parasolid-based systems like SolidWorks, Solid Edge and NX. IGES is a vendor-neutral ASCII standard (finalized as IGES 5.3 in 1996), so converting makes the part readable in CAD programs that cannot open Parasolid.Which programs can open the resulting IGS file?
IGES is one of the oldest and most widely supported CAD exchange formats, so nearly every 3D CAD system and many free viewers such as FreeCAD or CAD Assistant can read it. Its age means it is a safe common denominator when you do not know what software the recipient uses.
What information is lost in the conversion?
Only geometry is carried across - parametric features, feature history, assembly structure, materials and most metadata are not part of IGES and are dropped. A single Parasolid solid may also arrive as a collection of surfaces rather than a closed solid.
