How Can I create multiple rebar coupler in revit using dynamo

Is it possible to create multiple rebar couplers in revit using dynamo?

Possibly, see if this helps.

I tried that one but got error. And It cannot be selected more than two bars.

Great, appreciate that level of information being in first post as always.

Rebar is beyond my knowledge, hopefully someone else can assist.

Thanks a lot @GavinNicholls

Hi nahV5PBA, Gavin’s reaction is perfectly understandable for the amount of no context posts he/we see every day.

This isn’t a troubleshoot my script, or please write my graph for me kind of forum. It’s to help new users overcome obstacles on their Dynamo learning journey. We can’t possibly know what kind of errors you are running into like this, and you wont find anyone who will be willing to open the post linked by Gavin and figure out what error you are getting.

We are here to help newcomers and experts advance their Dynamo skill, not to do work for someone. It’s how i learned Dynamo up until this point.

Try to post images of your graph and where you are running into errors, instead of just telling us you’re running into an error.

I tried to insert couplers between two bars by using the dynamo script which is found in this forum.
But I encounter the error message as shown pic below. Sometimes it can be placed only between two bars. hopefully someone help to fix this issue. attached dynamo script too. Thanks

I assume this script is trying to place a coupler on all those bars as if they were all in lign, you’d need to create a filter to group bars that are on the same line into seperate lists (i assume, haven’t checked the python script)

@Garbage_Collector We cannot make group rebars and insert couplers. Thanks

Uhh ok that’s unfortunate!

Yes, it’s possible using the Revit API with Dynamo or Python, but native Dynamo nodes don’t currently support batch creation of rebar couplers. A custom Python node or API-based workflow is typically required to automate coupler placement for multiple rebars.
