Sculpture tools greyed out

As a complete newbie to Zbrush I must post the question. The Sculpture tools are greyed out whenever I create a ‘tool’ but become active when I import an obj file. Am I missing something?
Any help will be much appreciated. Thanks in advance.

Which version are you using?

Is your model in Edit mode? If not, press T after drawing the model on the canvas.
