Need the ability to add a main to a construction drawing as a parallel continuous line, as opposed to segmented/sectioned line with offset given

How to Join - break lines as single continuous parallel to main lines? Tried that functionality with below keyin's. This functionality was existing in V8i now intension is to implement same in MicroStation Connect edition.

For making parallel lines used InteropUtility.SetCopyParallel(Convert.ToInt32(content), ref message); functionality then break main lines were joined with below keyin but 

"choose last; drop curve; selview 1;selview 1;choose none"

"create chain automatic;%d;%d;selview 1"

Please suggest any affective way of implementing both copy parallel along with join if it has break lines as single continuous line.
