Choose the Update Views command
Tip:
To update a single view, select a drawing view and choose the Update View command from the shortcut menu.
When a part view is out of date with the part or assembly it describes, the border of the part view is displayed in the disabled color.
The Update Views command updates all part views in a document.
(Force Drawing Views to Update) If you hold Ctrl+Shift when you click Update Views, Solid Edge performs a full update, just as it would on initial view creation. That is, it rereads all of the model data to regenerate the views, rather than only the model data thought to have changed.
You can increase update performance for views of assemblies for which you do not need hidden edge information. On the Options dialog box, on the Edge Display tab, clear the Show Hidden Edges and Show Edges of Hidden Parts check boxes.
