make sure that you have a solid for subtraction. 

if you have solid, please check if it has any errors. you can check it by selecting in structure tree --> right click --> check geometry. 

Also you can try creating a enclosure manually and then use 'Combine' command for subtraction. 




If this helps, please mark this post as 'Is Solution' to help others.
