392 | Chapter 17 Change Existing Objects
You can trim objects to their nearest intersection with other objects. Instead
of selecting cutting edges, you press
ENTER. Then, when you select the objects
to trim, AutoCAD automatically chooses the nearest objects in the drawing
as cutting edges. In this example, the walls are trimmed so that they intersect
smoothly.
Extend Objects
Extending operates the same way as trimming. You can extend objects so
they end precisely at boundary edges defined by other objects. In this exam-
ple, you extend the lines precisely to a circle, which is the boundary edge.
You can extend objects without leaving the
TRIM command. Hold down
SHIFT and select the objects to be extended.
Trim and Extend Wide Polylines
Wide polylines trim and extend so that the centerline intersects the bound-
ary. Because the ends of wide polylines are right-angle corners, part of the
end extends past the boundary if the boundary is not perpendicular to the
extended segment.
If you trim or extend a tapered polyline segment, the width of the extended
end is corrected to continue the original taper to the new endpoint. If this
correction gives the segment a negative ending width, the ending width is
forced to 0.
