Hi Scott,
You have summed up what I am trying to do perfectly. I think my problem is I have used Basecamp for years and it is getting used to a new way of doing things. As you're no doubt aware in Basecamp as soon as you cut the file it splits into two files. It is just the way I have been used to these things for a few years, maybe thinking about it in 9 out of 10 cases the way Topofusion works is neater and more efficient!
I found the merge tool save as very useful. And the code idea sounds a very good one also.
My 'problem' at the moment is I have a 850 mile cycle ride and I wish to split this into first six days as separate files and then split each day into legs. But thinking about it splinting the legs may be as easy left in the same file.
And the last question. I can't seem to see a way of plotting a route to follow roads?
Excellent package by the way
