You will find the *.geo file as well as the *.stl file in the compressed folder. Your remark seems to imply I need to get the id number of the faces I want to extrude directly from my *.stl file. Are the faces consecutively numbered? I guess not, because gmsh doesn’t accept identification numbers like 0, 1, 2 or 3.
