Assigning Textures Using Classes. If you set up your file early on to use textures for specific classes that you want to texture then you have an advantage when it is time to assign the textures. By going to the classes dialog you can then texture all the objects of a specific class.
For example, you can set up a class for all the objects that are same material. Some Vectorworks objects (like the base cabinet) use classes to control textures.
