Hi Erik, it’s not about the .ai file. I just tried it with a blank file. To reproduce just:
1) make any Map View and draw a simple path with curvature tool
2) make a new file with Map View of different scale than the first one
3) copy the layer to a new file using Copy MAP Objects From and select add it to existing map view. It adds hundreds/thousands points when the transformation is done.
If I select “Make an unaltered copy of Map View” the path stays as the original one, but once I move the layer to the new map view, it gets transformed and adds hundreds of points.
In the same file though, when I change the scale of the unaltered copy of map view first and then move the path to the other map view via Layers palette (not via MAP Views) it doesn’t add the points.
So it must be something with MAP View transformations.
Cheers.
