All of you,
I agree with Luiz. But the mining students have to know what buttom use to produce good diagram. On ArGis, Gemcom, and blabla, they have to choice between Schmidt and Wullf projection. Have a look ! Most of the diagram are plotted in Wullf superior with structural structures! Nobody see that...expect one day a manager!
So,some hours to explain Wullf and Schmidt diagram are quite important !

Dear all,
I am in agreement with Mike and Alex, we have exactly the same problem in Brazil. I spent 6 years as a structural geology demonstrator, and every semester I heard the classical question: why should we learn how to make plots on stereographic projections if we have a computer program to do that. Even my class mates did the same when we were all undergraduate students. And, believe you or not, are working on petroleum and mining industry here in Brazil. In fact, to get job in many of the mining and petroleum companies (and we are not talking about small companies here), the candidates have to know Vulcan, ArcGis, bla bla bla. You don´t need to know even to make a simple 3D sketch, or to plot a foliation on a Schimidt-Lambert net, but if you know which buttons you have to push in such softwares, you will be certainly hired with a very good salary. I am not saying that computer stuff are rubbish, of course they aren´t. However, we must remember who we are, which training we had and have, and show to those people that we are not simple monkeys to push buttons on a keyboard. Maybe we will hear that we came from the OLD SCHOOL (I´ve heard that when I was doing field mapping with a master student which believes that field relationships were not important if we have mass spectometer...hahahahahahah), BUT WHO CARES? I was really bad on 3D visualization when I began to study structural geology, sometimes I still have terrible fights with the equal-area net, but I believe that with patience and lot of effort, we can do good work on structure and tectonics using pencil, field notebooks and paper sheets, and a net to plot structures.
sorry for my english & all the best to all,
Luiz
