splitting surface geometry

[Landau17]

Hi,
In CATIA V5 I've created surface model of a boiler for CFD simulation. Since the geometry is symmetrical in one plane in order to save time and computer power I would like to consider only one side of the geometry (left or right) in my simulation.
However, I haven't taken it into account earlier and I had mirrored some surfaces from left to right and vice versa.
But when I use option split option in generative shape design some of the surfaces that aren't directly cut through are left on the side I'd like to remove. I can't delete them either because in doing so I would delete on the side I'd like to keep intact.
What can I do to remove one side of the geometry completely without damaging the other one?

Any help is greatly appreciated.

Nasty problem, i suggest to first decide teh master side for one time on
then use serch command and check for mirror feature. Name and study each of them and then replace mirror with just rotation to the right side. It's a pain job but that's the way to get out.

Other solution faster but dirty is to copy the final model, paste as result with link, and perform a final cut.

Hi,
Try disassembling everything and delete/keep the required feature.

From your description, it sounds as though you could create a Join feature from the collection of surfaces you have created (provided they have been designed to have overlapping edges) and then utilize the Split command on the resultant Join feature.

I ran into this issue countless times when I was learning Catia. I wish I had known Dougsnell's solution a while ago, would've saved me some headaches.

What I do now to avoid this is "isolate" (or disassemble as sudhakarn suggested) my mirrored components after I am sure they are good. This is a bit tedious, but saves a lot of time when updating. The designs I make at work are quite complex and full of many components. If I don't isolate surfaces and features, updating after a revision is a nightmare.

I know that this issue didn't occur to you until much later, but take the time to plan out your course. An organized design (with proper Geometrical sets, bodies, products, etc), will make it tenfold easier to make revisions for you and anyone else.

Cheers,
