How to draw flow lines in a drawing

Hello everyone,

I need to make a concept drawing of a scrubber assembly with flow lines in it and it needs to look professional. I don't need a sophisticated flow simulation, just a few lines to show what's happening to water coming out of nozzles and gases going through pipes.

Is there any way to draw these lines in the assembly and have them show up in the drawing? I'm trying to use sketches but I'm having a hard time with that because the sketches display dimensions (which are only for the construction of the flow lines anyways), and they also display differently in the drawing than they do in the model. Also, if I use a sketch/sketches, is there a way to not display the endpoints of lines?
