given a number of lines and arcs that have been "joined". imagine some arbitrary number of operations later (ie: "undo" isn't an option) the operator would like to "unjoin" the joined collection into its constituent parts. does the union of SharkCAD Pro and PowerPack Pro have the functionality required and if so how is it done??

Hello Art

Maybe its better to use the group tool for combining objects if you want to later have the individual pieces. The join tool changes the object usually to splines and is unrecoverable after undo stack is lost.

I believe that most would like a composite curve tool like the polyline in AutoCAD, the ability to combine lines and curves into a single enitity but be able to explode it back to the original pieces if it was not modified or changed.

I'm not sure that it can be sustained in PunchCAD. You can script a polyline with .spl text import, but once it's in the UI, it's line segments all the way, no grouping. I've used TurboCAD since it was an AutoCAD analogue, and it used to be that profiles had to be closed to make a solid, so joining polylines was compulsory, but doing that exploded (deprecated) arcs and curves into line segments, as AutoCAD used to do in R12 and R13. Since then, TC has a compound profile option that automatically recognises closed profiles without insisting that they be joined or grouped, (or the user can stipulate what objects make up open profiles), arynd it also enables part history. Since that's been available, polylines are really only useful for editing AutoCAD .dwg files, although I think I read that the most recent version doesn't explode curves, don't know if .dwg accommdates them now as well.
