Deleting Holes
To create a domain inside the enclosure we need the imported objects to form a watertight structure. A first step in achieving this is to apply the Delete Holes operation that can find and delete cylindrical holes in solid objects.
Note: A geometry object that contains more than one domain is a nonmanifold object for which defeaturing operations, such as deleting holes, are not supported. Thus it is recommended to use the defeaturing tools before computing the union of the imported objects.
1
In the Geometry toolbar, click  Defeaturing and Repair and choose  Delete Holes.
2
In the Tools window all objects already appear in the Input objects list, and you can enter 6[mm] in the Maximum hole radius text field.
3
Click Find Holes.
The tool found 36 holes, which appear in the Hole selection list, and they are also highlighted on the geometry.

Click Delete All to remove all holes.
The holes are now deleted, and a Delete Holes 1 (dho1) node is inserted into the geometry sequence.
