Hello Keith,

I hope that you are well.

To apply a door structure to a specific door:

1. Access the material styles sub-method that you need the structure applied to

2. Access the sub-method you want to apply to structure to, select the structures tab, choose the door, and add the structure.

This will always identify the selected component with the chosen structure within the sub-method.

Please let me know if this requires further clarification.

Best regards, Isaac
