+# Function: derive()
+
+> **derive**\<`V`, `T`\>(`fn`): (`_`, `context`) => `ClassAccessorDecoratorResult`\<`GfxPrimitiveElementModel`\<`BaseElementProps`\>, `V`\>
+
+The derive decorator is used to derive other properties' update when the
+decorated property is updated through assignment in the local.
+
+Note:
+1. The first argument of the function is the new value of the decorated property
+   before the `convert` decorator is called.
+2. The decorator function will execute after the decorated property has been updated.
+3. The decorator function will not execute during model creation.
+4. The decorator function will not execute if the decorated property is updated through
+   the Y map. That is to say, if other peers update the property will not trigger this decorator
