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, the nearest displayed objects act as cutting edges. In this example,
the walls are trimmed so that they intersect smoothly.
You can extend objects without leaving the TRIM command. Press and hold
Shift and select the objects to be extended.
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 example,
you extend the lines precisely to a circle, which is the boundary edge.
NOTE You can trim objects without leaving the EXTEND command. Press and
hold Shift and select the objects to be trimmed.
Trim and Extend Wide Polylines
2D wide polylines trim and extend at their centerlines. The ends of wide
polylines are always square. Trimming a wide polyline at an angle causes
portions of the end to extend beyond the cutting edge
If you trim or extend a tapered 2D 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.
