Trim Object > Angle to Point (Trim Menu)

This command can be used to modify an existing object. If the object is a line, the line direction is changed. If on the other hand it is a circle part, the start or end angle is changed. The size of the alteration is determined by entering a point.

Any standard object can be identified and trimmed. Standard objects are in this case lines, circle parts and ellipse 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 position at which the object is identified (the "ID point"), affects the rest of the command. It determines which end point of the line or which arc angle should be altered.

After identification, a circle or ellipse (the "reference object") appears. This indicates the possible new end point positions.

The point to which the angle should be changed, can be entered using the mouse, by clicking anywhere in the drawing. A perpendicular is dropped from this point to the reference object. In most cases it makes sense to use the intersection of the reference object with another object as a snapping reference. 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).

If the trim object is a circle or ellipse part, then the angle at the end of the arc closer to the ID point is altered (see graphic).

Note a basic rule for trimming: The object changes, wherever 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.
