Using ArcGIS Pro 2.0 I've made a scene using a contour feature class. In ArcGIS Pro the contours look like this:
![](/legacyfs/online/364859_pastedImage_1.png)
Sharing the scene to ArcGIS Online the rendering is poor and the same contours look like this:
![](/legacyfs/online/364860_pastedImage_2.png)
Is there a way to increasing the resolution when sharing to AGOL?
UPDATE
I found this article on line aliasing. It hasn't helped.
