Hi Dave, so what kind of ghost objects are you seeing with the line, is it an extra point object?

Are you possibly calling update() at some time before you call calculate() ?

If so then you probably should leave out the call to update() because that's meant to be used for an interactive command, so things like UI objects are created during that call, in the case of Line there is a point object created to mark the beginning point.

If you do call update(), then you could call cancel() to erase the interactive stuff like the UI geometry though.

But if you call calculate() only and avoid calling update() the UI geometry should be suppressed.


But it sounds like you may be currently getting the regular "interactive mode" stuff created by a call to update() - if you just want to generate output objects directly and have them returned to your script then call calculate() _instead_ of calling update().
