To create a plan that is split into "Areas" like Area "A" and Area "B", right click on the view and select "Duplicate View"--- >"Duplicate as Dependent". Do this for as many "Areas" that you will have (If you have an area "A" and area "B" you will need 2 dependent views. The dependent views are now showing "outlined" underneath the main view, which will still show everything. Remember that dependent views carry annotation over from their parent view, so you can do all of your work in the parent view and use the dependent views to drag onto sheets.
In order to define the area that the dependent view will display, go to the "Drafting" tab--->"Scope Box" and define as many scope boxes as you have areas. Once you define the size of the scope box, you can then edit it's properties and give it a name for identification purposes (like" Area A"). After you have define each scope box by the area it will define, right click on one of the dependent views, go to "Properties." Under "Extents" the last option allows you to define a scope box for the extents.
*Note: When you create the dependent view, it will automatically check the boxes for "Crop view," "Crop Region Visible," and "Annotation Crop." If you are using a scope box, the only box you would need to check is "Annotation Crop." You can not uncheck these boxes unless you set your scope box to "none," uncheck them, and set it back.
