Would anyone mind telling me what is some of the possible errors I have in my model?
the attached are my grasshopper and rhino file.
Appreciated,
Willy
Did you accidentally open and older file with an older version of Honeybee? The latest version of Honeybee is not backwards compatible. Insert the honeybee_honeybee component in canvas and then re-calculate the file (press F5) and it should work fine.
