After you've put down building blocks or other objects and made connections, you can edit what you've built. First, select the item. Once the item is selected, you can move it, size it, change its appearance, or delete it.
Note: You can select items whenever the cursor changes to a Move tool.
The item will be selected, handles will appear on it, and its properties will appear in the Properties panel.
Once you've selected the building block or object, you can move or edit it. For more information, see Working with Building Blocks and Working with Objects.
