When creating or editing a structure where the chosen mast and foundation must be used together with an adapter plate, you can select a compatible adapter plate from the dropdown list in the 'Edit Structure' window, as seen below.
When you choose an adapter plate from the drop-down menu, the top and bottom gaps will be initially populated with default values, which you’ll be able to edit.
Alternatively, if you have selected a mast and foundation that don’t need to be used with an adapter plate, the adapter plate dropdown list and ‘Top Gap’ field will be greyed out. The ‘Bottom Gap’ field will be renamed ‘Gap', representing the gap between the mast and foundation, which you'll be able to edit.
The use of an adapter plate is recorded in the foundation details report. Find out more here.
