I’m a newbie. I created a shapefile layer and in that drew a polygon, the layer is visible and at the top of the layers list.
In ORS Tools, in Batch Jobs > Points (1 Layer), I select the various options I want and also select the polygon layer I created in the “Polyons to avoid [optional]” field. I left unchecked and also checked the “iterate over this layer” option next to the field, which made no difference.
The result for me is a path that goes through the polygon that I wanted to avoid. The polygon is avoidable.
