Manual/Studio Overview/Interface/Explorer

The Instances Model and Part are on the same level; neither is Parent to the other. Both of them are Parented to Workspace

Part is the child of Model, and Model is the Parent of Part.

The Explorer panel in Studio shows a list containing every Instance inside of a Place. This list uses the concept of parenting to organize all of the Instances hierarchically. If an Instance has any children, it will show an arrow next to its name in the Explorer. Clicking on this arrow toggles a list of all the children of that instance.

To make an Instance the child of another, drag it in the Explorer to the instance you want to be the parent.

To open the Explorer window, click on the View tab and then click the Explorer button.
