Just another great tool to save you time, and control your layers in an easier manner.
Bring back any 'turned off' layers to the current drawing, even if they are off on Xref level. You can easily manage layers in the following states: (see screenshots)
1) Off Layers
2) Frozen Layers
3) Locked Layers
4) UnPlottable Layers
5) Xref Layers
This app supports Autodesk® AutoCAD® 2014-2018 releases.
