MEANING = Select object to trim or shift-select to extend or [Fence / Crossing / Project / Edge / Erase / Undo]:

- Fence Option is used to select the object image by using the fenceline, each object will be selected when exposed to the trajectory fence line. Fence line can be irregularly shaped trajectory, but it is a straight line.

- Option Crossing the same as fence lines, crossing option is used to select the affected image object trajectories crossing the line and / or inside the lines crossing. In contrast to the fence, crossing the line in the form of rectangles.

- Project Option is used to working on 3D images. With this option you can cut objects that are not in one area. At the same Project option there are three sub-options, None, UCS and View.

None will make the trim option ignores objects located in different areas so that the cut only the objects in the same field.

UCS option will create an object based on a plan to cut trim UCS now and ignore the object is in the same plane or not.

View options using the fields seem to determine the line of sight cutting objects located in different areas.

- Option Edge will help you to cut objects that are not met by using a piece of pseudo-lines.

At the edge there are two sub-options option, which extend Extend and No, which is toggled or turns into default.

- Option you can use Undo to undo the last step you create the event of an error in workmanship. This command will create an object that has been cut back to its original form before being cut.

- Erase Option is used to remove objects that are not required when you run the command trim.
