What kind of answer! Such stupid was my question to have this kind of answer. In fact I had a course period and it was a successful one. I really learned a lot from this course which helped me a lot for the last two projects. The first lessons was how to import the point from the file csv. the second lessons until 9 lessons hot to edit the points, and then we continued with the surfaces, alignments, profiles, sections, assemblies and so on. As you see the two first classes ( Classes one"points" and Classes 2 "surfaces", which of one was divided into 9 lessons) are not in fact my job. My job begin from the classes 3, ( alignment). My question? in fact was for something that is not my duty, and my responsibility, because someone else is payed for this, and I am not a topographer.... However, thanks for the answer, even I did not? need it at all. Sincerely, madam not sir m.sotiri
