One way to edit an existing layout title block and border is to select all of the CAD and Text objects and resize them to fit the newly selected sheet size.
3D views such as elevation views cannot be rotated on a layout page. If you would like an elevation view to be rotated, send it to layout in a different format.
An elevation view can display in color on the layout page if you send it to layout twice: once as a scaled, dynamic view, and once as a static, un-scaled image.
When views are sent to layout you can specify a scale, or you can direct the program to select the scale that best fills the printed page.
