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.

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
