Dear Dan,
Please, find attached image about the process.
The layers (polygon to be simplified and line as barrier) are in the same projected dataset. We used the default gdb tolerance (0,001).
We want to block external vertices of the polygon layer, so I used the barrier. But the output shows overshoot and undershoot.
As far as I understand, that should not happen.
Thanks in advance.
Regards.
Fran
