OK, how do I do this one?
I have 2 roofs that I want to combine to one.
first I start with 2 surfaces, pick both and say create roof
then I went to edit roof and picked the hip that (bottom right) and tried to make a gable but only the bit over the porch gabled, the rest stayed as a hip
I have then tried to move the ridge line over but it changes the roof pitch
Im lost, what do I do please
