Does Ladybug + work with Rhino 6?


I just uploaded an image, left showing Ladybug Sunpath and right is Ladybug+ Sunpath. Is this a compatibility issue?



The answer is yes. Please refer to these websites.


I forgot to add this is a screen print from Rhino 6, I have uninstalled independent installations of Ironpython. Still no luck with Ladybug+ though.


@taylor_zhou Rhino 6 need Ironpython 2.7.5 or 2.7.7. You shound reinstall the Ironpython. Then restart the Rhino 6 and Ladybug, It should works.


Hi @taylor_zhou,
Can you please check if you have a file named at

C:\Users\Your User Name\AppData\Roaming\McNeel\Rhinoceros\6.0\scripts\ladybug


@minggangyin tried that already with no luck.

Hi @devang, the folder you mentioned does not exist, the scripts folder is empty. Should I create that and where should I locate the python file?

The default folder for LB is C:\Users\Your User Name\AppData\Roaming\Ladybug currently. Has that changed?



DId you use the grasshopper file to install Honeybee[+] that you get when you download it from food4rhino website? Does it install everything successfully?
I would suggest trying to create the folder and placing the whole ladybug folder at the location I mentioned. Make sure it has the file named Let us know if it doesn’t work.


Thanks @devang that seems to do the trick!
