Is there anyway to have one pipe go over or under another, so as to avoid having to make long round-a-bout journeys?

Pipes can cross at right angles, just drag the path of one over others. They cannot turn while crossing over others though, so there must be a free space after the crossing.

In the below exaggerated mess, the bottom end, for example, cannot go to where the cursor is without some ripping up of the existing pipes.

Not sure why this wasn't working for me before. I must have been trying to cross over a stair case shaped pipe. I'm too tired for this. Thanks. – Kevin Jan 8 '12 at 5:28
Don't forget, a track cannot cross itself, regardless of what angle they meet at. – Ronan Jan 8 '12 at 11:09
