Working with Symbols
Symbols allow you to place multiple instances of an item in your project. This can save memory, since all instances of a symbol simply refer to the original item and it can speed up moving around complex objects, since internal properties such as segment lists and gradient positions don't need to be updated with every transformation.
To create a symbol from an item, just pass the item to the new Symbol(item) constructor. When you create a symbol using an item, that item is automatically removed from the document.
To place instances of the symbol in your project, you can call symbol.place(position) on it, with the position where you want to place it.
For example, lets create a circle shaped path and place a few instances of it:
Selecting Placed Symbols
When you create a symbol from an item, that item becomes the definition of the symbol. Editing the definition of a symbol is reflected in all its PlacedSymbol instances.
