Process slice stacks with scripted actions rather than performing them manually one by one
In the Slice Commander, load a Lua script through
Main menu > Slices > 
Execute Lua Script, or through a selected slice's
Context menu > Extended > Execute Lua Script. This runs the script immediately.
Writing Lua scripts for slicing
Lua scripts for slicing are not written or at least managed using the Lua script library dialog.
Write Lua scripts for slicing in an external editor. Refer to the Slicing objects section in the Netfabb Lua API reference documentation in the online help. There are also example scripts in the <Netfabb>\Examples folder that can be used as reference for developing your own scripts.
