Hello, 

 

Try following these steps:

Go to 'Create' > 'Body Operations' > Set 'create solids' and merge bodies' (optional) to 'yes' > Select all the surfaces and execute the task. 

 

Otherwise, I would recommend you to use Repair > 'Stitch' option in Ansys Discovery/SpaceClaim. 

 

Thanks!

Nikhil
