What command to clean up and remove unwanted curves after two objects are unioned?

Hi,
V5.
I have a rectangular hole (2 in fact) that goes part way into a cube in the wrong place, I need to move it and make it vertical, my plan is to fill it, union, then remove the joints left, and create a new hole.

Unless one can take a hole and move it, resize it etc.

I once saw ‘magician impossible’ place finger over hole in card and move it across card !

I know Spaceclaim can do so.
so how do I clean up the resulting lines I see that are in fact not an object any more ?
item attached.

DeleteHole should work to remove the rectangular holes entirely.
MoveHole should work to move them (you will need to place reference points first probably).

Great, I will try those :slight_smile:

Thanks

Steve
