Command: EXTENDTO

This function extends the picked end of an object (or last segment) to the picked destination point in the direction parallel to the object.
The program provides an easy way to shorten or lengthen the linear object by a specified length (like STRETCH  but no need to make a rectangular selection over the desired end and specifying the direction of stretching). Works with the following object types of Autodesk® AutoCAD® and Autodesk® AutoCAD® MEP:
Line, LW_polyline, 2D_polyline, 3D_polyline, multiline,
Duct, Pipe, Wall, CableTray, Conduit, Structural Brace, structural Beam, Schematic line, Schematic pipe, DbMember.
The function works in 2D, 3D, and in any UCS.
