I try to use OffsetCurveGenerator to generate one sided buffers. I have a set of oriented polylines and the offset should always be generated on the left. But some are produced on the right side instead of the left side...
I checked the source polylines first and last coordinates to check the polylines orientation and it is always correct.
Is this problem known and is there a workaround to solve it?
In advance, many thanks for your help.
Best regards,
François
