If I have a sanitary tee in a run, and I click on the + to make it a double sanitary tee, it never works.I get this error: "The converted fitting was not defined in the routing preference. Please assign one on the connected curve types."

I can insert a doulbe sanitary tee in the main manually, and then reconnect the other branch lines.

Anyone know an answer as to how to make it work in the first place?

The double-sanitary fitting needs to be defined as a cross in the routing preferences of the pipe type.

I think it was already?

Go to the "Type" Properties of the pipe type you are using.  under the "Fitting" parameters, you can select what type of "Cross" to use.  select your double sanitary tee next to the Cross type.  You might have to delete the tee and re-create the connection for it to recognize the change.
