So I've only just started mucking about with Dungeondraft, so I may have missed something obvious, but I was having an issue with doors. If I have the Open Portals mode set to anything but 'None', all portals - closed, open, free-standing, whatever - seem to be treated as a window. I fiddled with various options in Dungeondraft and editing the boolean values in the json itself, and I couldn't find any setting that would draw a door line rather than a window line when I ran !uvtt. In the end, since I don't have any windows anyway, I just turned Open Portals Mode to none, which was the behavior I needed. I figured I'd bring it up here, though, just in case this was some sort of bug and not me missing something obvious.
