Switching to Sheet Workspace
When working on a Sheet, the SheetMode command lets you toggle from Model workspace to Sheet workspace.
In Sheet workspace, you display views of the model in Viewports, create borders, insert title Blocks, or add annotations, part lists, or legends, for example.
Sheets represent the paper layout of a drawing. You can create multiple layouts on Sheet tabs.
To switch to Model workspace, use the ModelMode command.
You cannot use the SheetMode command in the Model tab.
