Creating Roof with Python

1

I have been receiving this error when running my python script to generate a roof form:

rvt error

Any ideas why?

I am running Dynamo 1.3 on Revit 2016 on a Windows 10 machine. It’d be great to at least see if it runs on someone else’s machine.

Attached is my DYN file & Python script, as well as screenshots of both.

Thanks

pydyn node

py node

test_create_ceiling_py.dyn (4.1 KB)
pycode.txt (1.4 KB)

I’ve also attempted this route using dynamo nodes to receive the same error:
dyn nodetest_create_ceiling.dyn (14.3 KB)

I would prefer a solution in python, but something using nodes could suffice.

Thanks

Hi, I just started using Python and I am still confused, but I’ve tried this script and didn’t give any error. If might be of help for you…
