I have a 30 day trial of solidworks 2008. I have inserted quite a few tool bars but all except one are greyed out and i cant use any of the tools on them.On the features tool bar i want to use the extuded,boss,base comand. When i do place the curser over it,it does tell me what it is but nothing happens when i double click on it.This is the first time i have tried to use solidworks but i have used autocad before. THANKS FOR ALL ANSWERS. David
