I couldnt think of a better place to post this question since there seems to be many CC2/3 users about.

I'm mapping out a spacecraft, but I have found out that somewhere, all the lines for the hull have been duplicated. So instead of the hull outline being composed of 30 entities, its composed as 60.

I havent been able to find a tool to clear out entities that are duplicates so I'm posting here to see if anyone knows how to remove entities that have been duplicated.

Thanks for the help in advance.
