Hi: The only plugin that does NOT work is GenerateRoof v.3.0.
I installed and re-installed it several times, re-launching the software every time, with te same result:
--I always get the message: "Plug-in was successfully imported. Its features will be available in Sweet Home 3D at its next launch."
--After re-launch, it is always in the Tools menu, but it is grayed out!
--All the other plugins work just fine.
--And I should be ready with a house next Monday, but I can't without a roof.
Please, help.
