How to route pipes

This is a bit tricky.
First of all you can only route a pipe from a subgraph which has connection points.
For example the graphs under process have mainly all connection points.
Once you have placed a subgraph on the working area you can easily route a pipe either to another subgraph or just route it somewhere to the workplace (this is the frequent case).
By selecting the open end you can rotate the routing direction with the rotate button.
Note: The open end is sensitive to the direction where start with the next pipe.
If you want to make a branch you have to start with the MB2 parallel to the open node. If you want to continue in same direction you have to do the MB2 directly beside the open node.
