Specifying the Floor Finish for a Deck

When I try to add a floor finish layer to a Deck room, the following Information message displays:

"The deck floor structure typically has two layers: a deck planking layer and a joist layer with a framing material. Planking should not be in the floor finish."

What does this mean?


This message appears because, unlike other room types that use a finish material that spans the entire floor, deck planking is part of the structure and does not require a finish layer.

A finish layer can still be added, but this would be some other type of covering laid over the deck planking, such as astro-turf, deck carpet, etc.

How to add a floor finish layer to a Deck room

  1. Click inside the Deck room to select it.

  2. Click the Open Object edit button to open the deck's Room Specification dialog.

  3. In the Structure panel of the Room Specification dialog, click the Edit button to the right of Floor Finish to open the Floor Finish Definition dialog.

  4. Click the Insert button to add a new layer to the floor finish. 

    • Click in the Thickness text field to enter a thickness for the new layer.

    • Click the Select Material button to open the Select Material dialog.

    • Select the desired material for the new layer from the Select Material dialog, and then click OK.

  5. When this floor finish is set up correctly, click OK to close the Floor Finish Definition dialog. You will receive the information message listed at the beginning of this article. Click OK on this information message, and then click OK to close the Room Specification dialog.

  6. Select 3D> Create Perspective View> Full Camera , and then click and drag in the plan view to create a 3D camera view to see the deck's new floor finish.
