Hello,
I have an edges.obj file that is used for snapping in snappyHexMesh. This file is obtained from the .eMesh file of surfaceFeatureExtract, after removing unnecessary edges between patches using Blender.
After executing surfaceTransformPoints -rollPitchYaw for the geometry in .STL, the result is as expected, and displays properly in paraview. However, when I try to do the same with the edges.obj file, it's not possible to view it in paraview. Under the "Information tab" I see that both files have the same amount of points, however the rotated one has none cells.
Anyone knows how to rotate this .obj file properly, please?

You are a bit out of luck with that. As the name implies, "surfaceTransformPoints" is for surfaces and will ignore geometric entities that are not faces (eg, your lines). I guess there hasn't been much call for transforming edges only. It is probably easiest to transform the surface first *before* using surfaceFeatureExtract.
Don't know if this answers your question.
