I'm working on a project for a landscape nursery that likes to run drip line (actually soaker hose) above ground through their in-ground tree stock.  I created a drip line that is somewhat close to the estimated flow of soaker hose and drew each individual drip line which are about 20 feet apart (which is why I have to draw individual drip lines versus a hatched area).  I then connected a lateral (PVC) line to these individual runs of drip line.

Yesterday I needed to make some changes and add some more of these drip line runs and connect them to lateral piping, but I cannot get the two to connect which means I cannot size the zones.  So my question is how can I connect the two products together?

An example of this setup would be an electric valve, PVC lateral leaving the valve and then an above ground stand pipe every 20 feet with a hose connection that runs to the row of trees.  This is where the soaker hose begins.  I tried using a "transition" point within the drip equipment, but I cannot snap to that either with the drip line, only the lateral line can snap to it.

Let me know if I'm doing something wrong or if there was a change recently that is now preventing me from doing this since it worked before.

Thank you
