First of all, this is a great tool and I used it a lot to to develop software mock-ups and workflow. However, I have to say that the multi-segment tool is really so bad compared to other free tools, like Dia. I'm not sure if there is a better way to draw 2-segment path between to processes (or any other elements), but these are my methods (still bad methods though):
1. Method 1:
- Add a Straight Connector and connect one of its end to the first process, remove the arrow on this connector
- Add a Multi-segment Connector and connect one of its end to the second process
- Now the important part: drag the other end of Multi-segment Connector and connect it to the other end of the Straight Connector
- (Optional) Select both Straight Connector and Multi-segment Connector, right click on them and select "Group"
2. Method 2:
- Add a Straight Connector and connect one of its end to the first process, remove the arrow on this connector
- Add a Multi-segment Connector and connect one of its end to the second process
- Add a connectPoint, the connect the remaining ends of Straight Connector and Multi-segment Connector to this connectPoint
- (Optional) Select connectPoint, Straight Connector, and Multi-segment Connector, then right click on them and select "Group"
- (Optional) You may want to hide the connectPoint by changing its color
