This article shows you how to move and rotate an asset or a group in the editor
To move or rotate an asset or a group, start by selecting the asset/group you'd like to move or rotate by clicking it on the canvas. Once selected, a 2D manipulator will appear.
To move the selected asset/group, simply click and drag the center point to move it around. For more precision, click one of the arrows to move it in the side-by-side or top-to-bottom direction. You can also do so by changing the X or Z input fields in the Position section of the inspector panel.
To rotate the selected asset/group, click and drag the outer circle to rotate it, or change the Rotation input field in the Position section of the inspector panel.
Changes are autosaved in the Editor but don't forget to publish your model when you are ready to make the changes public.
