Implement the desire model manually through the user interface. When you are happy with it, use RevitLookup to analyse the result and find out:

1- let the user select the pipe whose the desired cross family type is defined in its routing preferences prior to hitting the tool button. 

2- extract the desired cross family type. 

3- do the NewCrossFitting()

4- use FamilyInstance.ChangeTypeId(desiredFamilyType.Id) method to change the created cross to the desired cross family. 

Hope this helps!

Hi,I mean i need to make sure the  pipe fittings to be generated is the type i want,when the  four pipes in different pipeType ,Instead of i don't know how to use LookUp to check what fittingType it generated.When i use NewCrossFitting,i find that what fittingType it generated seems to be uncontrolled,Maybe it has something to do with the order of parameters?

I believe you can simply place the desired fittings first and then connect their connectors to automatically generate the types between them. Read the series of experiments to implement a rolling pipe offset:
