I don’t like when I receive AutoCAD drawings with the properties overridden to other than ByLayer. It’s a bit hard to distinguish between layers when people do that. There are many ways to change them back to ByLayer. We can select all objects and set the properties to ByLayer or using Match Properties.
But it will be a problem when it has blocks that also have it’s property overridden. AutoCAD actually has a very handy tool for this purpose: SETBYLAYER. You can type it in command line/ dynamic input or accessing menu modify>change by layer. Don’t ask me where is it in AutoCAD 2010, haven’t found it yet.
You can see that this tool will change Color, Linetype, Lineweight, and Material back to ByLayer. You can change this, of course. For example, you want to change the color and lineweight to bylayer, but don’t want to change the others.
You can also see that this tool can change ByBlock to ByLayer. And you can also change objects inside blocks!
Command: SETBYLAYER
Current active settings: Color Linetype Lineweight Material
