When planks are joined together, you can use Avontus Designer to infill planks, and fill any gap between the planks.
In this example, we are going to fill the highlighted gap.

To do this.
Select the required Bay

Select Bay Details
Select Sides

Check the relevant checkbox to add the infill plank

Click Apply

You will be able to see the bays have been infilled.
Note that, you can also infill planks via the Bay Level Editor.
