Workshops for ArchiCAD?

You could start by looking at the Graphisoft website where they have many resources that can point you in the correct direction regarding education and training for ArchiCAD. The tutorials that they have are step by step with accompanying videos that teach as you go and are excellent. Beyond that if you want more, Eric Bobrow is an excellent instructor and has a AC Best Practices course the teaches the software and the most appropriate way to use it. Just jump in with these and you will be in very good hands.
