User would like the ability to control the length of a sweep along a curve. For example, if the user would like to stop the sweep short of the end of the path, the user is required to either shorten the path or perform an operation to cut off the unneeded geometry. Alternatively, the user would also like to be able to control the start point of the sweep. In general, once a path and a profile exists, the user would like to be able to control the start and end, regardless of the length of the path.
