390 | Chapter 17 Change Existing Objects
Change the Size and Shape of Objects
There are several methods for adjusting the lengths of existing objects rela-
tive to other objects both symmetrically and asymetrically.
Trim or Extend Objects
You can shorten or lengthen objects to meet the edges of other objects. This
means you can create an object such as a line first and then later adjust it to
fit exactly between other objects.
Objects you select as cutting edges or boundary edges are not required to
intersect the object being trimmed. You can trim or extend an object to a
projected edge or to an extrapolated intersection; that is, where the objects
would intersect if they were extended.
If you do not specify a boundary and press
ENTER at the Select Objects
prompt, all objects become potential boundaries. This is called implied
selection.
To select geometry within blocks as boundaries, you must use single,
crossing, fence, or implied boundaries.
Trim Objects
You can trim objects so that they end precisely at boundary edges defined by
other objects. Cutting edges can be lines, arcs, circles, polylines, ellipses,
splines, xlines, regions, blocks, and rays. They can also be layout viewport
objects in paper space.
You can extend objects without leaving the
TRIM command. Hold down
SHIFT and select the objects to be extended.
In this example, you clean up the intersection of two walls smoothly by
trimming.
