Begin by opening the Floor View, which can be found in the Level Navigation tab located at the top right.

After you have entered the Floor View, proceed to the Global Settings and Preferences section on the left bottom of your screen.

Within the Global Settings and Preferences, you'll find an option called "Floor Settings."

In the Floor Settings, you'll notice a parameter called "Tracing Background." Click on the drop-down menu located next to it.

To superimpose a tracing background, check the box against 'Show on Top'.

To change the opacity of the tracing background, navigate to the Opacity toggle, and either drag it or enter the desired opacity percentage into the Opacity field.

To hide the tracing background without deleting it, drag the Opacity toggle to 0 or enter 0 into the Opacity field.
