For buildings that are semi-detached or terraces, the terracer plugin seems to pay attention to the order the nodes were created/numbered, and thus on which side to split the building up (I suppose if it's fairly square-shaped). I don't see that a colour-reading auto-tracer could decide on which side to start drawing the building. For this reason I think it is quicker to use the building plugin to trace and then be ready to split up for numbering. But don't let me discourage your work and anyone who would find it useful. It is probably that this case is based on my current mapping of lots of square-ish buildings that are often semi-detached. Actually, we haven't thought if this would be helpful in any areas if altered for use on ponds/lakes (not really rivers broken by many bridges) and/or green woods/parks. -- Gregory o...@livingwithdragons.com http://www.livingwithdragons.com
