Как конвертировать IGS в OBJ
- Добавьте ваш файл .IGS - перетащите его в поле выше или нажмите, чтобы выбрать.
- Конвертируйте его в .OBJ за несколько секунд.
- Скачайте ваш новый файл .OBJ.
Чего ожидать
- IGES stores NURBS surfaces, not polygons; OBJ export tessellates them into triangles - lower the mesh deviation setting for smoother results on curved shapes.
- If the model imports as separate surfaces rather than a solid, run Part > Sew Shape in FreeCAD before exporting to avoid holes in the
.objmesh. - IGES carries geometry only - no colors, UV maps, or textures; add materials in your destination tool after conversion.
Часто задаваемые вопросы
Why does my exported OBJ have holes?
The source
.igs file likely has surface gaps. In FreeCAD, select all shapes and run Part > Sew Shape to close them before exporting.Is OBJ or STL better for 3D printing from an IGS file?
STL is more universally accepted by slicer software such as Cura or PrusaSlicer; use OBJ when the target is a rendering or animation tool.
Will the OBJ look identical to the IGS model?
Close but not exact - NURBS curves in IGES become triangle polygons in OBJ; increase mesh quality at export to minimize visible faceting.
Are `.igs` and `.iges` the same format?
Yes -
.igs is the old three-letter DOS alias for .iges; both hold identical IGES 5.3 data and open in the same software.Программы, которые конвертируют IGS: PolyTrans|CAD+DCC · 3ds Max (3D Studio Max) · Autoconverter · TransMagic · Afanche 3D Viewer for Mac · FreeCAD · Online CAD converter · Babel3D
