Thank you Don.
I will give it a try tonight, but I'll probably fail. I'll let you know.
I need it for two purposes:
1. Making an overview map of Datsville from the subdivision in town.dat. (Maybe post-editing of the Y and E values by

2. Making super-simplified models for previews of animations.
Thanks again,
/Tore
