When you're decorating, precision in dimensions is crucial for success. To simplify your process, navigate to Settings -> Dimensions, find the setting named 'Object Distance'. By turning this feature on, you'll be able to view the exact distance between objects. This helps ensure there is ample space for comfortable living.
Measuring the distance using the ruler
Click on the Ruler icon in the menu to summon it. It’ll appear in your project. Now you can measure the distance between objects by placing a ruler between them.
Note: if you can't find the Ruler, make sure you're in 2D mode. You can only use the Ruler in 2D at the moment.
If you need to set the ruler to be of a specific length - you can also do it! Just click the ruler icon at the top bar of the editor, and then simply set the needed length! Easy as that!
