Build Dynamo Button
If you are creating a Dynamo from an object with no animations, the Build Dynamo Wizard dialog box appears. By default, the Build Dynamo Wizard assigns the object a sequential Dynamo name. In the Build Dynamo Wizard you can rename the Dynamo, as well as enter text describing the Dynamo and the object itself.
If you are creating a Dynamo object with animations, the Build Dynamo with User Prompts dialog box appears. For more information on how to use this dialog box to create your Dynamo object, refer to the Creating Dynamo Objects with Animations section.
