Layer & Layer Set maintenance.

[ACADuser]

I have 30+ layers that I use on details.
Over time they need some cleaning up.
So in one layer set I made them the correct color and line weight.
I did not have the "Modify All layer Sets" checked. So how do I update all 32 layers in all layer sets?

Also I have a layer miss named but both are in use somewhere in the plan CAD Details.
I want "_Light 1" and "_Light_1" combined into "_Light 1"
Deleting "_Light_1" is not allowed because it is in use. There should be a way to combine the layers.
In Autocad when you attempt to delete a layer in use you have the option to delete the objects on that layer or change objects to an existing layer.
How can I manage that situation?

Thanks in advance.

Thanks for the link but no Joy.

I think I will have to update all the line weights again with the "Modify All layer Sets" checked.

Learn the hard way.

The way I did it was to go thru all the line items in one std floor plan layer set.

Check "modify all layer sets" at the top of the LDO DBX "before" changing anything.

Change each line colour, line weight, and line style as required and then "OK" it.

Also just re-selecting each colour, line weight, and line style but not changing them will change them in the other layer sets.
