Anyone got an extrude algorithm? That is, given a footprint and a few params (would need to define) a means to create multiple shapes.

I like this idea, but anyway it is implemented I think it would be a good feature to have. Beyond OSM, I have run into quite a few people that are generating data sets with building outlines and some of them have height info. A lot of this data is getting generated from plot plans and tax roles where the number of floors is included which can be interpreted as height. -Steve Lime, Steve D (DNR) wrote: > Probably a bit of overkill for what amounts to a visual effect.
