Hello guys i�m very new to Zbrush i started 2 days before.
At the moment i�m making my way trough tutorials and all the Pdfs 
So i will describe my problem.
If i select curve mode like in the tutorial for making a flower (http://www.pixologic.com/zclassroom/homeroom/lesson/3d-brushes/#curve-tri-fill) then the line where u can pull, transform or distort how i would say is red and black striped.
I don�t know how to say but i can�t add more mass to the curve just dragging it.
In the Video the line is white and there are arrows if i can see it right.
Does he have some options changed in the video which he did not mention?
I got another question in the moment but this i�ll maybe find out on my own if i go on at the pdfs but i would be a help if you could tell me the solution.
I modeled a face and saved it as a document not as a tool, if i open the document i can�t change into edit mode.
This is all i want to know i�m sorry for disturbing for some noob questions and for my bad english either 
Thx alot, Gerock
i uploaded a picture of my problem.
