I am editing 3D points, next to a point cloud. The problem comes when using the move tool, to reposition the points (shapefiles) in a specific place in the point cloud. The tool is very sensitive to movement (sometimes it disappears) and only lets me move points in the X,Y plane and not in Z.
Move, rotate, or scale a feature—ArcGIS Pro | Documentation
To move a 3D feature in a scene, drag the selection along the x-, y-, or z-axis handle.
There are axis handles permitting x,y and/or z value changes
@JaimeSáezPrat check the layer properties for the Points. It sounds like you have them 'On the ground' and need them to be 'At an absolute height'
