It is easy to do copy design on CAD files and get new items and BOM, but some of our customers use vault to manage their design with no CAD models or with non-structured CAD files, so it is impossible to use copy design function on their files and promote new items and BOMs.
The only feasible way we found is to export items to a csv file, change the file manually in excel, and then import items with the modified csv file. But I don't think this is a good idea because it is very easy to make some mistake and it is not easy work.
We think a copy design function for items is needed here, it should just like the copy design function on files, we can choose the new item number for the copied item, choose which items to be reused, replaced, or copied as well, together with their attachments.
We also think a SaveCopyAs function for item is very useful in such situation, a new item will be created immediately with the same BOM stucture and same properties, then we can modify the new item as needed.
