Trim Object > Length / Radius to Point (Trim Menu)

This command can be used to modify an existing object. If the object is a line, then its length can be changed. If, however, it is a circle or circle part, then its radius can be altered. The size of the alteration is determined by entering a point.

Any standard object can be identified and trimmed. In this case, standard objects are lines, circles and circle parts. The objects are always treated as a whole, sectors and segments are treated like arcs.

The identified object is referred to as the "trim object"

The point at which the line was identified (the ID point) affects the rest of the command. It determines which end of the line should be moved. Refer to the graphics at the end of this section.

If the trim object is a line, a straight line appears, extending the line. It is called the "reference line", and can be used to snap to its intersections with other objects.

The point to which the length or radius should be altered, can be entered using the mouse, by clicking anywhere in the drawing. In most cases, it makes sense to use the intersection of the trim object or reference straight line with other objects as a snapping point. To do this, the SHIFT key is kept held down during point entry.

After entering the point, the trim object is trimmed. If the trim object is a line, the end point of the line nearest to the ID point is moved (see graphic).

Note this basic rule for trimming: the object is always changed where it is clicked on.

If a non-standard object (e.g. a curve or surface) is to be trimmed, then the command Trim Object > Resolve Completely must be used to break it into its constituent parts. These can then be trimmed.
