Rebar option not found


I am using Dynamo 0.91 version. Can someone please tell me how to get rebar options in that?

Please elaborate, what do you mean by Rebar options?

I can’t use any of rebar commands… Importing packages also not working…

Time to upgrade… that Dynamo build is over 5 years old. Head to and get Dynamo 2.0.4 the latest supported version for Revit 2018 and 2019 and you should be good to go. If you’re in 2017 go for 2.0.3, and if you’re in 2016 it’s time to upgrade your Revit model as you’re missing years of updates (including some important security ones).
