Hi Daniel, have no experience with structured meshes, so I cannot help you here. But maybe someone else knows more - CC of this answer goes to the gmsh mailing list.

I have a STEP part and when load it into gmsh, I'm able to mesh it directly by doing: Mesh -> 3D. However the mesh I obtain is an unstructred and I need a structured mesh. My file has only one volume and about 25 surfaces. Therefore this part contains many lines. If I got it right, in order to generate a structured mesh I have to use the "transfinite line" to define the number of nodes of each line. So my question was, Do I have to define the number of nodes of each line manually (using transfinite line) or there is a clever way to do so?
