Hello @yousrakadcha78 Sorry that you found these nodes and that they aren’t working for you! The node called
Model.FromElements is intended for use with Hypar Elements, which you can create using the other nodes in that package. A script that looks like the one below should work and create a model that you can then import into Hypar. (The yellow warning is saying that some conversion has failed, not that all walls failed to convert)
I’m very curious, what are you trying to accomplish with Hypar? If you need any other assistance please don’t hesitate to reach out to us here at Hypar with the email email@example.com
You should also know that we have mostly discontinued development of our Dynamo Package in favor of our Revit addin. You can read more about using the addin here.
Note, if you use our addin, it may interfer with the Dynamo package.
