Hi @Arun_Prakash, thanks for sharing. Just wanted to know if we have any other method to solve the same as when ever i run this script my laptop hangs even for generating pipe on one line ---

Hi @chuongmep and @T_Pover I have tried both MEPover and OpenMEP and think that i did everything correct. No matter what i have tried i could not get the diameter ( or width/height for duct ) implementing in the script. All the other things ( location, pipe type, system type ) is correct. But both scripts creating pipes/ducts with a default size, not the size i made as input, and returns “null” instead of pipe or ducts. I tried different type of numerical inputs as diameter. Can you help me to understand what is wrong? ![OpenMEP](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/5/b5c61948af78b8f90f7c0a546f34ae5d1fa2ef54.jpeg) ---

Can give me see the current unit of the project and information of your pipe when you draw by manual ? ---

pipe size units are in “mm”, I tried the sizes from the routing preferences, Also tried different numbers like “0.04, 04, 40, 400” did not matter… ![resim_2023-12-28_144314903](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/5/f575c2559e8ff1b361f886330575ec219ddff70e.png) ---

Could it be something related to the decimal seperator, Which makes python to not get correct? ---

As i am a new user here, it does not let me upload the revit file as attachment. But if it helps I just started a new project with Revit 2023 Metric Systems template, and try to use these scripts to decide the modeling technique. ---

Also tried to select a pipe from the model get its diameter and make as input for diameter and still got the warning and null out with pipe modeled in a default diameter. ![resim_2023-12-28_153757513](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/b/ebcc6009febb937eadc20b8d4d5a4339ab81c3ea.png) ---

Hello, I’m trying to install the [OpenMEP](https://forum.dynamobim.com/t/openmep-package-feedback-thread/) package, but I download and install the package, but it doesn’t appear in dynamo. Do you know what I can do? ---

Guys, I followed the entire discussion and tried to generate pipes through these 2 nodes, I didn’t try through [OpenMEP](https://forum.dynamobim.com/t/openmep-package-feedback-thread/) because I’m having problems with its installation. But even after following the entire discussion, both nodes have the same problem, does anyone know how I can solve it? ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/2/423fc9b1442314809dce448e2fe821b22a76e1a7.png) ---

if you use mepover nodes be sure you have dynamoironpython package installed as well …if in 23-24 use 2.7 ver. 2.5 [Previous page](https://forum.dynamobim.com/t/pipes-from-lines/25450.md?page=2)
