part outside the outline

Is it possible to render a part which is outside the outline but has a common edge?

Is it a bug in F4,
or the outline should be larger and include this part,
or can we correct tagging to solve this?

It’s not a bug, it’s a feature. :wink:

to make the part visible, it must be within the outline. otherwise it must be a seperate building.
