Use DesignCenter. A solution faster and versatile.

Works fine if the complete layerset is non existing in the target drawing.
But if one of the layernames already exist, and the properties of that layer (color, lineweigth,..) are different, the new definition of that layer will not be inserted into the drawing.

As an additional tip to Ignacio’s suggestion of using Design Center – One advantage of using DC to import layers [instead of inserting a block] is that you can control which layers you want to import (i.e. using the Ctrl and/or Shift keys). In other words, you may only need to import 1/2 dozen layers whereas you might end up importing over 100 layers you don’t need if you insert the block (and then have to take the time and effort to Purge the unwanted layers)

I try it in acad 2007 , but it didn’t work, any idea why?
