Hi I just realised that in the default polygon style construction, whether its residential or industrial , is always defined as industrial 0x0c. I understand the' logic' , in that there are many 'mobile' industries constructing residential or industrial buildings. In my city there are numerous large construction sites, all of them constructing residential housing. If I were unknown to the city and plan a route through an industrial area I would expect to find the following : a) industrial blocks / units / working businesses b) roads entering and crossing industrial areas safe from barriers,fencing,cones,mud-sweepers,grumpiness or foremen etc Personally I would provide a separate polygon , ie 0x27 perhaps Just a thought.
