copy materials list and assign layers of multiple files

[roberto sacchetti]

hello;
I have three files (two buildings and a townhouse) that have the same materials.
I uploaded the materials and then applied to the first file, but how do I export the materials and layers to which they are associated, on the other two files?

1. Use design centre (ctrl + 2) to add the layers in the assigned file to the unassigned.
2. Copy and paste the unassigned file into the assigned on and rename.
3. In both this will work if your material assignment is by layers.

thank you;
I solved by making a copy and paste, and I have pasted the relevant materials of the layers !!!!!!
