Only flat and gabled roof types

[Acknar]

Hi,
The addon page mentions having support for a variety of roof types and there seem to be files for them but they do not appear in the default roof type dropdown. Is this normal and how do we access these rooftypes?

Those roof shapes will be created if they are contained in your OpenStreetMap extract.

So I need to put in different coordinates for them to appear? I looked at several locations and can't find a place that offers another roofing option. I tried major European cities as well as capitals and smaller towns in countries around the world

The default area in the base version of the addon contains multiple roof shapes. You try it out:
12.36902,51.33,12.37983,51.33721

The default area has various defined rooftypes but the option for default rooftypes when none are defined remains only flat or gabled

The default roof shapes were limited to only 2 of them intentionally. It's very unlikely that all buildings have a dome or onion roof shape.

For these particular shapes I agree, but hipped, half-hipped, gambrel and mansard roofs are shape types that make up the majority of many European towns and cities. I am focused on Paris right now which has a very homogenous urbanism with mansard roof as the default. This roof type isn't listed in the supported roof types but at least being able to select gambrel roof as default roof type would get me closer to the intended result.

in line 843 of the __init__.py of the gui directory of the plugin there is a tuple of tuples that exposes the default roof types to the GUI of the plugin.

items = (("flat", "flat", "flat shape"),("gabled", "gabled", "gabled shape"))

If you append a tuple for gambrel roof shapes like so

items = (("flat", "flat", "flat shape"),("gabled", "gabled", "gabled shape"), ("gambrel", "gambrel", "gambrel shape"))

you'll be able to select gambrel as a default roof type through the GUI. If you'd like to fork the repository or have that feature for yourself locally it's a fairly easy change to make.

Keep in mind that if you decide to expose the hipped or mansard type roofs to the GUI and select them as the default the majority of the buildings in your map will likely have flat roofs as those roof types are only supported for quadrangle building outlines.
