Trim or Extend in 3D
You can trim or extend an object to any other object in 3D space, regardless
of whether the objects are on the same plane or parallel to the cutting or
boundary edges. By using the
PROJMODE and EDGEMODE system variables,
you can choose one of three projections for trimming or extending: the XY
plane of the current UCS, the current view plane, or true 3D, which is not a
projection.
In true 3D trimming or extending, objects must intersect with the bound-
aries in 3D space. If the two do not intersect when you trim or extend an
object in the current UCS XY plane, the trimmed or extended object might
not end precisely at the boundary in 3D space. The following procedures
illustrate trimming and extending using the three projection options.
To extend an object
1 From the Modify menu, choose Extend.
2 Select the objects to serve as boundary edges.
To select all objects in the drawing as potential boundary edges, press
ENTER without selecting any objects.
3 Select the objects to extend.
