Hello,
I downloaded the package “Modelical” in Revit 2020 Dynamo Version 2.3.0 and its working fine as i am using this node for creating automatic wall creation from rooms. But when i downloaded the same package in Revit 2019 dynamo version 1.3.4 , the node is missing many of its nodes including the one i need. What should i do to get that worked in Revit 2019 Dynamo version 1.2.4 too. Below are the pictures of the same package with its nodes in both versions.
Revit 2019 should support 2.0.4 - I recommend upgrading and see if that fixes it.
https://dynamobuilds.com/ - the 2.0.4 install is the one to try.
