Creating route in animation



I’m new to AfterEffects and I’m not sure how to do some things, especially this one… So, I have animation like this ,imagine same thing, but camera goes through nature… and I need to draw a line that follows some route, but don’t know how… I have found only examples to do that with pen, but I’m not sure how to do that… Should I draw line for each frame? Something like this: (from 0:27)?

Thank you!


WIthout seeing the actual project and what you need to happen, from your description, it sounds like 3d stroke from Red Giant might be the solution you’re looking for.
