Need a hint on faking 3-d stroke type fx in motion

I have an idea for an fx shot in a blood donation spot that involves a red line that starts at one side of the screen, from say a small red box, screen right over white limbo, and draws across in a serpentine sort of way, branching off to terminate into numerous, let's say simple square boxes, screen left. See, I can't show needles going into arms, but I want to create a visual of the plastic tubing carrying the donated blood to multiple recipients.

What I don't have are 3-d stroke or Illustrator to make a path. I can probably hack something together in Lightwave, but was hoping to do everything in FCP and Motion for this.

The 3-d stroke needn't actually be 3-d, just serpentining, kind of like following a wandering garden hose. As the red line branches off, I'll have litle red boxes on the branches fill, and maybe pop in pictures of people's faces with them, showing how one donation helps many.

Motion is not a program I'm strong in yet, so any suggestions regarding how you would execute that in Motion are welcome.

Especially welcome before about 2PM today:-P

Can't help you immediately but try this for some tips, it's pre-3D:

This is my standard sigfile so do not take it personally: "For crying out loud, read the freakin' manual."

I think this is possible without any extra plugins. You can use the bezier or b-spline tool to make an open path set the, then in the Inspector, you can set the Shape Style to something like the airbrush or one of the light paths, and animate your spline. you may need to use masks to reveal parts of the spline over time.
