Why, when I move polyline in AutoCAD it changes the polyline elevation? Why when moving COGO Points in Civil 3D they lose their elevations? When I copy objects in AutoCAD they change their elevations, why?

AutoCAD Elevation OSNAP
The system variable OSNAPZ was introduced back in AutoCAD 2006 version. It controls whether object snaps are automatically projected onto a plane parallel to the XY plane of the current UCS at the current elevation. According to Autodesk’s site. Or in simpler words, OSNAPZ controls whether the objects/cursor will Snap and change the Z value (elevation) of the object.
To copy or move without changing the election, type on the command line OSNAPZ and enter 0.
OSNAPZ, 0 – Osnap uses the Z-value of the specified point
OSNAPZ, 1 – Osnap substitutes the Z-value of the specified point with the elevation (ELEV) set for the current UCS
