Trim and Extend Spline-Fit Polylines
Trimming a spline-fit polyline removes the curve-fit information and changes
the spline-fit segments into ordinary polyline segments.
Extending a spline-fit polyline adds a new vertex to the control frame for the
polyline.
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. In the TRIM and EXTEND commands, use the Project and
Edge options to select one of three projections for trimming or extending:
 The XY plane of the current UCS
 The plane of the current view
 True 3D, which is not a projection

Resize or Reshape Objects
You can resize objects to make them longer or shorter in only one direction
or to make them proportionally larger or smaller.
You can also stretch certain objects by moving an endpoint, vertex, or control
point.
Lengthen Objects
With LENGTHEN, you can change the included angle of arcs and the length
of the following objects:
 Lines
 Arcs
 Open polylines
 Elliptical arcs
 Open splines.
