In trimming geometric objects, the program deletes a line or curve segment to its nearest point of intersection with other objects. When the object to be trimmed has no points of intersection with other objects, it is deleted entirely.
To trim a line or curve segment
NOTE: This is necessary if you want to apply the trimming only to a group of objects, but not apply it to other objects to which the object you want to trim is also connected. The trimming is applied only to the selected objects, and not to points of intersection that fall outside the area of the selected objects.
A contextual edit bar appears.
NOTE: When the Use Selected button is pressed in, Prinect highlights and trims any other objects which do not intersect the selected ones as whole objects, without breaking them down to potential segments. When no objects are selected in the graphical area, the Use Selected button is unavailable.
The segment becomes highlighted to its nearest points of intersection with other objects. For example, if the segment is part of a line, Prinect breaks the line to its smallest possible sections defined by its intersection points with other objects. If the Use Selected button is pressed in, the trimming is applied to the nearest point of intersection with the selected objects.
