create a new ItemType from Part

Thanks Chris. With regards to have 1 database hosting parts for multiple projects, each project has its own parts, and parts for a project should not been seen by anyone outside the project. what is the best way of handle this? I was thinking to link parts to a team, and team would represent a project. Team members/identities would contain users for a project. How do we default the team to the team a user belongs to when the users add a part? It gets more complicated if an user belongs to multiple teams. Also I think team is  used for other purpose in innovator, e.g. ECO. Would it have other impacts? Your thoughts on this? Frank
