You can open an item with a non-Solid Edge dataset or one that has no dataset and create a new document.
In Open File dialog box, set the Files of Type to Items with No Solid Edge Documents.
Select the item from the list and click Open.
Choose a Solid Edge template from the list displayed.
In the Upload document dialog box, add a description, assign a project, or set other attributes, and then click OK.
The new file opens in Solid Edge and if it has structure in Teamcenter, that structure is reflected in PathFinder.
