Autodesk Revit Architecture

[#1]

Hi,
I am beginner in using Revit Architecture.
When I use ( Paint icon) to add a material , I can't find some materials. For instance (Ceramic Tile 4 Blue). How can I find such materials?
thanks

When you say "I can't find some materials", this prompts the questions where did the material go. Assuming you had it before and assuming you will find it in a new file if you open one, I would Transfer Project Standards to get it back into your project again.

See this link for detail on Transfer Project Standards:

If however you never had this material go here for detail on Materials:

Thanks for posting.
