Hi !

If no one has changed it the “camera” is located at 0,0,0 from the start, but you should check your clipping planes so that you are not clipping your lines.

And if you want to zoom I would suggest you keep the camera where it is and change the field of view instead, this is the “correct” way to zoom.
