Trim Object > Angle to Object (Trim Menu)

This command can be used to modify an existing object. If it is a line, the line direction is changed. If however it is a circle or ellipse part, then the start or end angle is changed. The size of the change is given by the intersection or tangent point with a given object.

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.

Any part object in an existing object can be identified as a reference object. This may be an edge of a rectangle, the arc of an ellipse segment or a circle arc within a surface.

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

The position at which the (part) object was identified (the "ID point"), affects the rest of the command. If the trim object has several possible intersections or tangent points with the reference object, the point closer to the ID point is chosen.

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 arc end angle closer to the ID point is changed (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.
