To create a boundary polyline
1 Click Home tab ➤ Draw panel ➤ Boundary.
2 In the Boundary Creation dialog box, in the Object Type list, select
Polyline.
3 Under Boundary Set, do one of the following:
■ To create a boundary set from all objects visible in the current
viewport, select Current Viewport. Avoid this option for large, complex
drawings.
■ To specify which objects to include in the boundary set, click New.
Select the objects that you want to use to create the boundary. Using
this option automatically selects the Existing Set option.
4 Click Pick Points.
5 Specify points within each area that you want to form a boundary
polyline.
This area must be totally enclosed; that is, there can be no gaps between
enclosing objects. You can select more than one area. Click Island
Detection if you want internal closed areas to be included in the boundary
set.
6 Press Enter to create the boundary polyline and end the command.
The command creates a polyline in the shape of the boundary. Because
this polyline overlaps the objects used to create it, it may not be visible.
However, you can move, copy, or modify it just as you can any other
polyline.
