With the Boundary command, you can designate a specific area of a drawing for operations such as hatching and dimensioning. You create a boundary polyline by selecting an area inside a closed loop. The area you select can be bounded by a single closed entity or by multiple entities that intersect.


NOTE You cannot use a spline or an ellipse entity to create a boundary polyline.


In cases where entities intersect, IntelliCAD® 2001 interprets the boundary as the closed loop closest to the point specifying the area. In the following figure, for example, the area point selected in the rectangle results in a boundary consisting of the closed loop nearest the point selection, as opposed to the closed loop formed by the rectangle itself.

 

 

Specified point (A) in area contained in rectangular polyline.

Resulting boundary (B).

To make boundaries more specific, you can create a boundary set. A boundary set specifies which entities are considered in determining the boundary path. In the following figure, the circle and triangle are the selected entities. If you select an area anywhere inside the circle or the triangle, the result is a polyline that bounds the shaded area.

 

 

Triangle (A) and circle (B) selected as boundary set.

Point specified in the selected area (C), which results in a new boundary around the shaded area.
