Description
Trims or extends a line, arc or ellipse to another entity.
Usage
Choose the limiting entity to which you want to trim or extend one or
more other entities.
Choose the entities that you want to trim to the limiting entity. Often
there are two possibilities for the entity to be trimmed. In the example
below, you might want the top part of the line to remain in the drawing and
the lower part to be trimmed away. In that case you would have to click the
trim entity at the upper part. Always click that part of the entity which you
want to retain.
Right click twice or press Escape twice to terminate the tool.
