I couldn't find anything doing a google search, so I thought I would ask here. I am new to mapping, in fact I have only made a floor with some walls. I would like to have something I can log into steam and walk around with to get a sense of size, not to mention I might learn better if I have something to go off of. Are there any framework / templates out there? Not necessarily a whole huge working map, but something I can download a few samples of "not quite finished" but not compiled maps, and then alter and change them?
