You need to draw big room around your external walls, which is your future roof projection. Then select this room and use plugin
sooo... i'm just selecting the interior room when i shouldn't be? if i then make a room that extends outside the building, it should work?
i'll upload a picture of what i have so far, so you can see if you can spot any glaring problems, aside from the obvious need for an external sized room
not sure how to upload photos here exactly so ill link to it, as well as try to use the image linker system used here, so sorry if theres more than 1 copy
