Hugin usually does a great job, with minimal/no effort.
Once in a while, nothing will get it to do what I want...
The enclosed pics and .pto files are my effort to join two parts of a German bus station sign, the left side with the schedule and part of the right, the right with a map and some of the right end of the schedule. I should have overlapped more, of course, but there SHOULD be enough to connect them. (There are 13 CPs, plus the line, between them)
I even indicated several lines CPs in the base of the sign, to help line things up, but as the resultant pic shows, they don't line up, and are not a line.
Am I doing something wrong, or is this a bug (and if so, how to describe?)
