Great question for autosprink, I haven’t used it before so I can’t tell you what it does never mind how. ---

Because you are using pipe types it will be a Tap ore a Tee not a mix. This has to do with the way Revit handels the pipe types. Tee makes form 2 pipes mainly 4 parts 3 pipes and 1 Tee. Well a Tap would make 3 Part, 2 Pipes and a outlet. You could change the behaver if the taps where different CAD layer types and assigning this to a other Pipe Type. > [@martinm](#): > > Hi @SPARTAN I used parts of your code to make this script Assuming you used those parts of my script. 😉 ---

Hello Sir… Good day to you… I want to use your dynamo script, but it shows some error in 1. List.GetitematIndex-“Warning: List.GetItemAtIndex operation failed. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index” 2. PipeBy Lines-“Warning: List.GetItemAtIndex operation failed. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index” How to solve this one sir… Please help me… ---

> [@jacob.small](#): > > Further the uses of AutoCAD are infinitely more elaborate than anyone realizes as it doesn’t force any significant standard on the users. Programmability with AutoLISP was a big reason for AutoCAD’s popularity. We could get our own customization done without having to wait for the app’s developers like the competition (E.G. ComCode). Nowadays, that brilliance has trickled down to Dynamo with a similar effect. You may try this logic for joining each element to the next one: ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/6/26c6e5fe3e24df8c8ef6ca6857ddd610ddacbed8.png) [Previous page](https://forum.dynamobim.com/t/cad-to-revit-piping-with-fittings/78123.md?page=1)
