5.5 Retopology Groups (Layers)
From 3D-Coat Wiki
Let’s take a look at the “Retopo Layer” tab now.
-Layers. As you can see in the screenshot, you can now have more then one layer to retopologize if you wish. They can be reordered by drag and drop, they can also dragged to the trash if you no longer need one. Double clicking a layer will allow you to rename it.
-Visibility. Each layer has it’s own visibility icon, allowing you to toggle them on or off.
There are icons along the bottom of the tab as well, from left to right they are:
Subdivide. Allows to subdivide the whole selected layer.
Symmetry copy. Copies an entire layer symmetrically. Symmetry must be active for this to work.
Select all faces. Selects all polygon faces of the current layer.
Move selected faces to current layer.
Delete layer. This will delete your current active layer.
