Layout View Box (2D)
Insert 
Geometry Rectangle
(Drawing Sheet Level)
Use this command to create bounding box geometry
around one or more 3D layout views. This can be helpful if you want to
see a view's extents or "foot print." The required inputs include
the view and a direction to orient the box. Optionally, you can enlarge
the box and specify a step size increment. You can also place the box
on a unique layer so that it can be turned off before printing.
View - Select layout view (or views) to enclose. Its x and y bounding box values will be displayed in the Optional Inputs section below.
Direction - Specify a direction vector. This direction determines the default x length. The view's positive x direction is selected by default.
Length (X), Width (Y) - If only one view is selected, these values will show the default x and y lengths of the view's bounding box. You can enter a buffer distance to enlarge the box by entering a positive value in the field below each length.
Step Size - Defines the step size that the lengths of the box will snap to. Leave this blank to use the actual values of the view's bounding box.
Layer - By default, the box geometry will be placed on the active layer. You can enter a different layer or pick the folder icon to select a layer.
