Can't extrude or cut on model

[pontemt]

So I started on this project recently and was not the original modeler.  This section of pipe has some problems where I'm guessing a sweep went wrong.  I've tried everything I know to do to try to fix this section but haven't had any luck.

- This model has no tree and is shown as one soild "base"

- I tried to extrude cut the bad section

- I tried spliting the bad section

- I exported the file as an IGES and then tried to remove bad section

I'm sure there are some other round about ways I tried that I can't think of but in the end nothing has worked.

Can some one give me some ideas of how to fix this section of pipe?

Thanks,

Mike

Do you still have the original file (before any attempts to "fix")?

Hi!

You can delete some faces and reconstruct the system with some loft, sweep, patch surfaces. In the end, stitch all surfaces to have a solid.

Yes I do.  I didn't want to post it since it has information that I would rather not share.

Can you go into more detail about how to delete faces.  I have little experience with surfaces.

Ok I figured it out and yes that worked. Thanks
