Srry for this N00B question but when i open one of my documents It dosent give me the brush i was working with and i dont find it 
like when u open a sample sphere It gives u a brush that u edit with where is it? 
Don’t save the document. That saves a pixol snapshot of your canvas. It does not save your model. Document>Save As is used when you’re creating a scene in ZBrush.
Instead, use Tool>Save As. This saves your model so that you can edit it later by using Tool>Load.
I strongly recommend www.pixologic.com/zclassroom and www.pixologic.com/docs These sites will answer your noob questions. 
Holy sh 
ok great thats just great Well btw Thanks
