I have two the same the dwg file A and B. I create a new a single layer in A and move all entities to this single layer, then delete all layers in A reserved for the layer and 0 layer . Then open the B, insert the block A to B. Now, everthing is Ok except the color. In my mind , the color of block A in B will have the same color because I set all the entities color bylayer,but it is not.
Why is that and How can I set the color of these entities to the color of the singe layer?
