hi! I’m using ghpython to write some stuff but stuck at some silly bug…
I’m trying to make my script as simple as I can, code is as followed. my input is a simple plane list (I specified the type list and plane), and I draw a circle.
import rhinoscriptsyntax as rs
from ghpythonlib import components as ghcomp
import scriptcontext as sc
xo = x[0].Origin
xz = x[0].ZAxis
a = ghcomp.CircleCNR(xo,xz,1)
print a
this works if I use gh battery directly, but in ghpython it returns None…
hope someone can help me with this…
