A symbol set is a group of symbol instances that you create with the Symbol Sprayer tool. You can create mixed sets of symbol instances by using the Symbol Sprayer tool with one symbol and then using it again with another symbol.

Artwork created with the symbolism tools

As you work with symbol sets, keep in mind that the symbolism tools affect only the symbol or symbols selected in the Symbols panel. For example, if you create a mixed symbol instance set that represents a meadow with grass and flowers, you can change the orientation of just the grass by selecting the grass symbol in the Symbols panel and then using the Symbol Spinner tool. To change the size of both the grass and the flowers, select both symbols in the Symbols panel and then use the Symbol Sizer tool.
