Hello. I checked out your file. Its not clear to me where you were having issues. It would be better to include annotations and more clear indications of where/what is the problem exactly. For something like this a simple screen shot can sometimes be quicker and easier to let people on the forums get a quick look. Uploading a file with a big model and a bunch of geometry is not going to help anyone to help you.
I’m guessing you figured out the fix for this by now though.
