Using ArcGIS Pro, I have a 2D layer in California. The feature is a line-split-at-vertices w/ Z points.

I exported the feature to a .MAPX file and then imported into the Mt. Egmont (New Zealand) 3D tutorial.

How do I copy the feature from the imported California layer over to some location on Mt. Egmont?

I've been trying using copy/paste but keep getting "Paste Features failed".
