Type EXTRIM or ET at the command line
EXTRIM allows you to select a Polyline, Line, Circle, Arc, Ellipse, Image, or Text as the trim edge.
Sample of how the command works.
Draw a rectangle with a series of lines and or polylines crossing over it.
Now type EXTRIM and select the rectangle.
Now specify the side to trim on. (The side you pick is where the objects will be deleted.)
If you pick outside the rectangle, it
trims everything crossing the rectangle around the outside, leaving
everything on the inside.
If you select inside the rectangle, it trims all the lines inside the rectangle and leaves the lines on the outside.
Give it a try – It is a huge time saver for trimming large files. You will be shocked at how fast it gets rid of the extra lines.
