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. And select the "DWG File" tab.

Look for the option labeled "Edit DWG Layers." Click on this option to open a modal or dialog box that lists all the layers available in the .DWG file.

In the modal that opens up, you'll see a list of all the layers within the .DWG file. These layers typically represent different elements of the drawing, such as furniture, walls, fixtures, and more.

To control the visibility of a specific layer, click on the checkbox of the layer you want to manage to turn the visibility on/off.

After selecting the layer, look for an option like "Apply" and click on this option to turn off the visibility for the selected layer.

Once applied, check your drawing to confirm that the visibility of the selected layer has been turned off.
