So I am trying to translate 3D sketches that are circular. When translated to igs cad, some of the circles go missing or partly missing. The only solution we have found is using splines, which take forever. Any ideas?
Looks like the b-slpine type 126 entities are having some issues..
You might try to export type 112.. and see if that is any better? (image attached)
Personally, I'd export only the faces which represent the edges (your scribes).. or the combo of them both faces and splines for reference...
If the surfaces from which the edges are extracted are not planar, a true arc or circle cannot be generated. Initially I thought, that might explain it.
I measured some of circles and found that they are true.
In the original SolidWorks file, if you select and convert an edge of a hole in a 3D sketch does it indicate an arc or spline?
