Defining a boundary

When you create a boundary, you select an existing entity or multiple entities to define the boundary.

To define boundaries from enclosed areas

Advanced experience level

   1   Do one of the following to choose Boundary ():

    On the ribbon, choose Home > Boundary (in Draw) or choose Draw > Boundary (in Draw).

    On the menu, choose Draw > Hatch > Boundary.

    On the Draw toolbar, click the Boundary tool.

    Type boundary and then press Enter.

   2   In Boundary Set, optionally specify a subset of entities to consider when creating the boundary:

    Click Select Boundary Set.

    In the drawing, select the entities to consider when creating the boundary, and press Enter when finished.

The Boundary Creation dialog box displays again and the Current Selection Set option becomes selected automatically, which indicates that the entities you selected will be considered when creating the boundary.

You dont have to select entities again using Select Boundary Set.
The Current Selection Set option uses the last set of entities you selected with Select Boundary Set.

   3   Mark Island Detection if you want to consider all internal, closed boundaries, called islands, for defining a boundary.

   4   In Entity Type, choose whether to create the resulting boundaries as polylines or regions. Regions are available only for program versions that support working with regions.

   5   Click Pick Internal Points.

   6   In the drawing, click inside the area whose closed perimeter forms the boundary, not on the entity itself. If desired, continue clicking inside additional closed perimeters.

    7    To complete the selection and create the boundaries, press Enter.

To define a boundary around a hatch

   1   Type hatchgenerateboundary and then press Enter.

   2   Select the hatch entities around which you want to create boundaries, then press Enter.

The boundaries are created as polylines and are not associated with the hatch entities.
