When you are ready to save one of your sculptures that you've created in ZBrush, you want to make sure that you use the controls in the Tool palette. Now I have my oldMan_v01 model drawn the canvas here and I'm in Edit mode. Let's say I have finished sculpting for the day and I'm ready to move on with something else. To save this, I make sure that I open the Tool palette and I choose Save As. When I do this, a dialog box opens and I could save it to my local disk in the ZTL format, which saves all the information about the 3D sculpture. Next time I start with the ZBrush I can use the Load tool button to open this model and continue sculpting from where I left off.
It's important to understand this because you maybe tempted to save your model using the controls in the document palette. But if I try and save a digital sculpture in Edit mode using the document palette, I'm going to get a warning. I will do Save As. ZBrush is going to ask me if I want to save the document or do I want to save the tool. If I save the document, the 3D tool is going to be dropped to the canvas. It's going to be converted to pixels and I'm no longer going to be able to edit it as a 3D sculpture or a 3D model. It's just going to be frozen there, so I want to make sure to save it as a tool.
Once again, if I choose that I get the ZTL format and I'm good to go. If you save a 3D model as a document you are going to lose a lot of the work that you have put into the model.
